Well, Solar lights are considered to be one of the most reliable and secure implements that a home can rely on these days. Outdoor solar lighting is a very attractive and environmentally friendly way of illuminating the area around your house.

These lights have solar panels attached to them, which absorb the sun’s energy and use it to charge an internal battery when put in direct sunlight. When night falls, the battery will be used to power LED lights that will light up your yard without the use of any electricity.

Sound great right? Now here comes the difficult situation to choose the perfect battery for the solar lights. You don’t need to worry about this as we have tried to provide all we can in this article to let your confusion vanish away.

Buying Guide For The Best Rechargeable Batteries For Solar Light in 2021

After the solar lights are exposed to the sun, it has internal batteries that store up energy. The accumulated energy in the batteries will illuminate your compound when the sun sets or is minimal. It is important to position the solar such that it receives maximum sun exposure.

In addition to this, it also depends on the solar batteries. How long the solar needs to be exposed to the sun is determined by the form and condition of the solar rechargeable batteries. As a result, the solar panel that generates energy from the sun and the battery that stores it has a significant impact on the lifetime of solar lights.

A battery can clearly make or break solar lights. As long as the cells are fully charged, they provide a large amount of solar power to the solar lights.  When electronics fail to work, however, batteries are often blamed.

Isn’t it true that the first thing to check when the solar lights stop working is the state of the batteries? They either need to be recharged or replaced.

But imagine replacing them every now and then if you use a non-rechargeable battery? Another burdensome task right? So it’s better to get yourself the most durable rechargeable batteries available after considering the features and price details before you buy the Best Rechargeable solar light with battery.

Features of the Best Rechargeable Batteries For Solar Lights in 2021

Types of Rechargeable Batteries For Solar Lights:

  • Nickel-cadmium batteries:

Nickel-cadmium batteries (also known as NiCad batteries) were once very common. In reality, back in the 1990s, they were thought to be the best rechargeable batteries on the market. They were famous for portable devices due to their lightweight, but since portability isn’t a problem for you when the Nickel cadmium batteries come to solar light, this benefit isn’t something you’re interested in.

As compared to alkaline batteries, these would not experience a visible voltage drop when they are depleted, which is a significant benefit. They are, however, not the most common option when it comes to purchasing rechargeable batteries for solar lights, as you will discover.

  • Nickel-metal hybrid batteries:

Nickel-metal hybrid batteries (abbreviated as NiMH) are a newcomer to the industry (at least when opposed to alkaline batteries), but they’ve rapidly risen to the top. When choosing between NiCD and NiMH for solar lights, most people prefer NIMH.

They’re also thought to be a safer option for solar lights and other battery-powered devices than NiCad batteries. They can carry more electric charges and are more environmentally friendly to dispose of. They are similar in size to alkaline batteries in terms of size.

  • Lithium-ion batteries (Li-ion):

Lithium-ion batteries (Li-ion) are a form of battery that you’ve probably heard of before. They’ve been around for a long time, but it wasn’t until the 1980s that they became famous. In reality, this form of battery provides the majority of the power for your laptop or smartphone.

The greatest advantage these lithium ion batteries have over NiMH batteries is that they charge in half the time, but the biggest disadvantage is that they are very costly.

  • Lithium-phosphate batteries:

Lithium-phosphate batteries (abbreviated as LiFePO4) are a type of lithium-ion battery that is far superior to the original. As compared to Li-ion batteries, their voltage drop is even smaller, which is why they are often the first option for those who need batteries that do not rely heavily on voltage circulation circuitry.

If you’re thinking about buying them for your solar light needs, keep in mind that they can also make lights shine brighter and last longer (even when they’re almost out of power).

  • Chemical Product:

Chemical compositions vary between rechargeable batteries. Lithium-ion batteries, copper, cadmium, lithium, and iron batteries are examples of these chemicals. Each of these battery chemical compositions performs and functions differently.

When used in solar lights, lithium-ion solar batteries rechargeable provide high-value operation and efficiency. Other, more environmentally friendly batteries are available. Look for batteries that are free of poisonous components to protect your health.


Whatever the situation, solar rechargeable batteries perform admirably. Solar batteries only lose about 10% of their capacity at 0 degrees Fahrenheit. In warmer temperatures of around 86 degrees Fahrenheit and above, they must work a little harder; their performance would drop by around 20%.

Battery Size:

Before buying rechargeable batteries, it’s necessary to think about the size and type of battery. A, AA, AAA, and other units are used to categorize different groups. The various sizes are compatible with various devices. The most popular rechargeable battery size for solar lights is AA.

The function is important because solar rechargeable batteries aaa are used in a variety of devices, including remote controls, toys, game controllers, and sound systems. Look for batteries that can be recharged to power your solar light and other gadgets.

Battery Power Capacity:

The most desired feature of rechargeable batteries is this. The life span of a rechargeable battery is determined by its power capacity. A battery’s power is measured in Ah or mAh. The power of most rechargeable batteries ranges from 600 mAh to 100 mAh.

Batteries have different life periods. Each life cycle increases the amount of energy available. As a result, you can save time and money by not having to purchase new rechargeable batteries after a shorter period of time than predicted.

Solar lights with long-lasting rechargeable solar power batteries can provide excellent efficiency during the night. When you buy high battery capacity for your solar lights and other gadgets, you will be in a better spot.

Energy efficiency:

It’s crucial to think about a rechargeable battery’s energy performance. Rapid energy recharging can provide high efficiency while using less energy.  Since solar lights rely on solar energy to run, the best rechargeable batteries can take four to five hours to fully charge.

When the sun’s strength falls below a certain level, the implements would be able to control the lights.  The energy efficiency of batteries can be measured in terms of how well they resist power loss while not in use. The full capacity loss can be minimized when batteries are not used for a long time.

Number Of Batteries:

Many of you who want to install solar lights around your home will almost certainly need multiple lights. As a result, you would need a large number of batteries, as each light would need several batteries. As a result, all solar light batteries available come in a pack of multiple solar rechargeable batteries aaa.

This includes 6 batteries, 8 batteries, 12 batteries, 16 batteries, and even 20 batteries in various pack sizes. And, as you would imagine, a larger pack size of 20 or so batteries will provide excellent value for money.


The first thing to look for to ensure this is the number of charge cycles they have. While some have 500 charge cycles, some could have 1000 charge cycles for longer battery life. However, the included warranty is the most important factor to remember when purchasing reliable batteries for your solar lights.

While some batteries come with a one-year or two-year warranty, there are a few that come with a three-year warranty for added reliability and peace of mind.

Available Price:

While considering the price of a rechargeable battery for solar lights, you should take note of your budget. The solar batteries rechargeable are not costly enough to buy, so they generally fall within your budget. The price mainly depends upon the number of cycles it provides and battery capacity.

However, rather than focusing solely on the price, we recommend that you consider other factors as well. We recommend you buy high-quality rechargeable batteries for your solar lights as they would serve you best in a long run.

FAQs Best Rechargeable Batteries For Solar Lights in 2021

What kind of solar light batteries do you use?

Solar lights usually use AA batteries. NiMH or NiCd batteries can be used. The number of rechargeable batteries in a solar light varies depending on the configuration, but most use four. In comparison to NiCD solar batteries, NiMH batteries work well in cold weather.

When it comes to rechargeable batteries, how long do they last?

The recharging period rating determines how long a rechargeable battery can be used at full capacity. The maximum number of times a battery can be recharged differs. A battery with a 2000 cycle rating will last you years, while one with a 500 cycle rating will last you less than a year.

Is it possible to use standard AA batteries in solar lights?

Standard AA batteries cannot be used in solar lights. The explanation for this is that standard AA batteries have a short life span and can only support you for a short time. Solar lights include rechargeable solar power batteries that can be charged and stored throughout the day.

At night, the accumulated energy is used. So, if you want to fuel your solar lights with rechargeable batteries, that's the way to go.

Is it a good idea to charge the new rechargeable batteries first in a charger set?

Well, it is not mandatory. I mean it’s not something you have to do it. The majority of the time, these new rechargeable batteries have some charge, but a small percentage of them do not.

However, once you attach these solar rechargeable batteries 3.2 volt to the solar panel, they will begin to charge as soon as the panels receive sunlight. However, you can theoretically charge them with any charger package (if you already have one) to get an immediate result.

Which battery is better rechargeable or non-rechargeable?

Non-rechargeable alkaline batteries will work for your solar lights temporarily, but this is the worst choice you will make. It's a slow but steady death for solar lights.

Batteries that aren't rechargeable will inevitably corrode the solar lights' terminals. Your solar lights will not work if the terminal is corroded. As a result, your solar lights will be totally useless in a short period of time. As a result, never consider using alkaline amazon solar batteries to fuel your solar lights.

How To Charge Batteries Using A Solar Garden Light?

These are the solar driveway lights I got a little solar panel on top and on the blog, I go to survival this blog met a guy named River rider said that you could buy these at Walmart and they’ve got double-a batteries in them that are rechargeable and I bought one and sure enough it’s got a standard rechargeable double-a battery in it so I’ve got some old rechargeable batteries that I used to use in a digital camera I’m going to put them in here and I’m going to set these out in the Sun and see if it works if I can take the batteries out and use them in my flashlights will that be cool a free way to charge double-a batteries.
Okay, I just can’t stick these things in the ground like they were intended to no I got to make it a little more complicated that’s just the way that’s just how I roll these stakes are intended to be driven in the ground and then this to be set on them like that but I’m going to screw these down to this 1 by 4 and it’s hard to do that looking through the viewfinder I just I missed it there so those will be screwed to this board like that and then I’m going to mount this board in a way.

So it can be swiveled to follow the path of the Sun you know like in the morning have this oriented north of South and tilted a little bit to the east and then about noon come outset it straight up and then in an afternoon turn it towards the west to get a full charge out of these little solar panels so I’m going to set this up and I’ll show you what it looks like okay I’ve got the little spikes mounted on this board here and looks like it’s finished but wait is there any way I could make this more complicated.

I think I can well I managed to make it a little more complicated and mounted it to a pipe with a wingnut that you can loosen and aim this towards the Sun and not only that but you can turn it as the year progresses and as the Sun settles in the West you could point it towards the West just to get that much more direct sunlight on those little solar panels and now the real test is going to be to put them rechargeable doubles in here and see just how well it does and that’ll be my next clip well here’s the thing.

I made I pulled it back out of the ground because you couldn’t turn it like this and the reason is I cut this point on the end and then hammered it down to the ground and it wouldn’t turn easy enough so not wanting to make this as easy as possible I’m making a little rod here for this is going to be hammered in the ground right here and then this is going to slide over it like that and it’ll rest on that big washer and it will be able to turn without any problem.

And I got these boxers just tacked on here right now fixing it well them washers on good and grind the diameter I’ll have to grind the diameter a little bit in order to fit up in here but I’ll show you the finished product, okay and my junk drawer in the kitchen I had these rechargeable batteries that I used to use in my digital camera and they’ve been in there God probably a year and a half maybe two just sitting there so I’m pretty sure they’re completely dead or nearly dead and I’m fixing to put them in the solar lights and my next clip will be of me a hammer in this steak in and showing you my latest complication to this thing Breezie you’re hugging my shot alright there it is I’m fixing a slide the bracket.

I made over that now you see the way the shadow is I’m going to aim this perpendicular with that line of that shadow and I won’t aim this up you probably won’t be able to see the Sun but the Sun is just a little past noon it’s probably one thirty-something like that like a little wrapped up there in my shop complicating this so I’m going to lean this towards the Sun there we go and in about four hours when the sun goes down I’ll come out here and pull the batteries out and stick them in a flashlight and see if they’ve changed them.

Upwell the sun’s getting a little lower it’s 5:00 in the afternoon and I’m going to pull a couple of these batteries out and stick them in a flashlight and see if three and a half hours of sunshine have charged them up enough to light a flashlight so I’d only go I only got one available hand then it’s going to take two hands to undo the lids off of these and pull the batteries out so while the next clip will be of me turn the flashlight on and see if it’s got enough juice the batteries okay I got the lids off I got the batteries out and look at this.

It’s not a hundred percent bright but for just a couple hours of charging that’s pretty impressive so in the event you don’t have electricity and you need a way of charging up some double-a batteries using solar these were four bucks each and you know a couple of hours of fabricating this little thing but you don’t really have to have that you could Jam these in the ground and they do just fine so that’s a pretty handy thing no and I Oh River Rider a debt of gratitude.

What are the right batteries to replace the ones in my solar lights in the garden?

It’s important to use batteries with the same voltage and power as the ones you removed from the solar lights. If your solar lights came with NiCd or NiMH 1.2V 600mAh aaa solar batteries, for example, we suggest replacing them with our 1.2V NIMH AA 600mAh solar light batteries.

The power of your old batteries is typically indicated by a mAh rating on the batteries. You can replace your battery with one with a slightly different mAh capacity as long as the voltage is the same; we suggest getting new batteries with the closest mAh rating possible.

Okay today I’m going to be showing you how to supercharge a solar power LED light this is the cheapest light you can buy I bought it at one of the big retailers for two dollars and 48 cents I got ten of them and their LED or single LED and then take a single rechargeable double-a battery so this is light we’re working with the top actually twists out and the batteries inside there so I’m going to show you how to go ahead and upgrade that to number one to have more capacity so it runs longer stays on longer at night and to so that if you have these place in an area that doesn’t get sunlight for the majority of the day your light will still be able to maintain.

And it won’t you know run out of battery juice after a couple of hours okay here’s the actual light itself you twist it off the top some of them some of these types of lights will have actual small screws where you have to remove them remove the small screws to get to the battery but it’s still double a battery in there this one is convenient enough to where you can just pop out the pop-out that piece and the battery goes in into the receptacle there it’s a single battery single light-emitting diode okay so this is the battery that came with it and notices how it’s it’s rechargeable double-a it says solar on it now that would lead one to believe.

That you know that’s that this is specially made for solar of devices and they are – the lights are very cheap they work they were like two dollars and some odd cents apiece so about Talib but very closely at this number okay that’s the reserve capacity this thing has that’s how much power it can hold on to when charged okay and they tell you that the manufacturer tells you to recharge these or I’m sorry to replace these once a year but the problem I’m having is my lights aren’t staying on very long because the spots that I’m in the don’t get stay get sunlight but they don’t get sunlight long enough to fully charge this battery.

Or there may be a day or two where it rains and so they don’t get as much and then they don’t work properly okay so I’m going to put this down this is a nickel-cadmium rechargeable battery 400 an H and it’s one 1.2 volts and that’s that pretty much explains that here I have an older energizer the new ones are 2300 mah this actually was one that I bought a while back for especially for digital cameras I actually tested this but you can see even with 23 you know 3 6 times 4 is 24 so this battery has six times the reserve more than six times the reserve capacity of that battery I just showed you that came with its unit.

Okay so let’s take a closer look at it it’s rechargeable it’s 1.2 holes good this has got a lot more reserved capacity pack of four of these is about $10 at Walmart or you know similar stores whatever about $10 for Packer for these double A’s okay and like I said the new ones I just bought some new ones today they all seem to be 2300 mah which is still a huge increase over the 400 mah that the factory lights come with so what would so what is all this about this is about my light staying on I want my lights to stay on I want them to be more versatile so by installing this battery and I want to make sure it’s fully charged if you buy it knowing the package they come pre-charged if you already have it.

You want it fully charged and you install it in the light and you put it out there in the evening and then you know it has the reserve capacity to then be recharged and it can go without a recharge for a debt for a day if you have rain or something like that and still work again like I said I’ve tested this so this is how we’re going to supercharge our $2 solar LED lights this is all we’re going to do we’re going to go out and we’re going to buy some rechargeable energizer and these can be recharged it says on the package up to 500 times so that’s more than that’s a little more than a year if it’s being and I’m assuming that’s a complete discharge and recharge which is not what we’re going to be doing we’re going to be still than certain cases it may fully discharge but you know we’re going to be trickle charge topping it off so it should last longer than that actually because we’re not going to be completely running.

It down and then completely recharging so that’s how that’s all you need to do to supercharge it I’m going to put this energizer in here as you can see because I have the solar side down the LED is lighting thinks it’s nighttime and then I’ll put the battery back cover back on and then what will happen is this.

The light fixture will go back on to its base see now it’s out it’ll get back onto its base and it’ll perform much better than it did when I first took it out of the box with this battery and remember you’re still going to have to replace this battery every year but this battery is not going to have the kind of this battery is not going to have the capacity to take it there to of rain and then still work where the other the energizer will it has that capacity so that’s how you supercharge a two dollar and fifty cents LED landscaping light.


It will be very simple to have full energy and efficient system for your solar lights after reading this study. Furthermore, you will have high-quality lighting and protection during the night.

To do so, take into account the power as well as the degree of longevity and life cycle that each rechargeable battery can provide. This way, you won’t waste money on batteries that would let you down later.

The level of longevity, on the other hand, is critical because your solar lights are constantly in use outside. As a result, high temperatures will not cause the solar rechargeable batteries to melt. Similarly, lower temperatures would not stop rechargeable batteries from working.
