From one of the most renowned battery brands, it has an extremely long duration life with more than four years in your solar lights. With large capacity for hours of continuous lighting, it’s greener and made with 4% recycled batteries.

POWEROWL AA Rechargeable Batteries at 2800 mAh

This has the largest-rated capacity of our review combined with an extremely long service life of four years. They are the best to keep your lights on even after a rainy day.

Why Do You Need Solar Light Batteries?

Your solar lights are very simple electronic devices. They are made of basic components, but each of them are essential:

  • LED lights
  • Mini solar panel
  • Solar light batteries
  • Electronic controller

Our sun is intermittent by nature; therefore, it will not shine the same all the time. Consequently your mini solar panel will not produce the same amount of energy daily. However, you will need light every day after sunset.

Solar light batteries will store the energy produced by the mini solar panel for your solar light to shine bright during most of the night, usually 6 to 10 hours.

What Are Solar Light Batteries?

Solar light batteries are rechargeable batteries. They are found in the standard size AA with a nominal voltage of 1.2V. They can be recharged directly in your solar light.

On their packaging, you will often see an indication like this one: AA 1.2v 600mah NiMH rechargeable solar light batteries.

  • AA is the standard type of rechargeable battery.
  • 1.2 V is the nominal voltage of the battery.
  • 600 mAh is the battery capacity.
  • NiMH is the battery technology.

Currently, there are two main solar light battery technologies: NiMH and NiCd.

What Is NiCd?

NiCd stands for nickel–cadmium. This type of battery has one nickel oxide electrode and one cadmium electrode. They are the oldest types of portable rechargeable batteries. They were the most dominant technology in the 90s but lost their market share to the NiMH battery.

Check out our NiMH vs NiCd comparison chart to see their main technological advantages.

What is NiMH?

This stands for Nickel Metal Hydride. This type of rechargeable battery developed in the late 60’s offers several advantages compared to NiCd and is now the leading technology in solar light batteries.

NiCd vs NiMH for solar light batteries

For a better understanding of both technologies, we have summarized in the chart below their main features.

Type AA batteryAA battery
Nominal voltage1.2 V1.2 V
Life cycle duration Up to 1000 cyclesUp to 2000 cycles
Self-discharge rateHigh (10% per month)Very low (less than 1% per month)
Support high discharge rateYesPartially
Temperature behaviorVery good at low and high temperaturesGood
Memory effectStrongVery limited
SafetyContain highly toxic materialRecyclable

In the end, we see that NiMH batteries, although not as robust as the NiCd batteries in hot and cold weather, offer more advantages.

However, aside from the material technology, what would be the main criteria to choose the best solar light battery?

Five Main Criteria to Choose the Best Solar Light Battery

When choosing a solar light battery, you are protecting the environment and saving money. Solar light batteries are rechargeable and will save you hundreds of regular alkaline (non-rechargeable) AA type batteries.

Have a look below at the main criteria that we have considered for our 10 best solar light batteries of 2021.

Battery Capacity

The main criteria when choosing your solar light batteries.

It is rated in mAh.

It ranges from 800 mAh to 2800 mAh.

The more storage capacity you have the longer your light will shine during the night. You can also store more energy to cope with rainy days when the sun cannot fully recharge your battery.

Number of Recharge Cycles

This is the life duration of your solar light batteries.

It ranges from 400 cycles to 2000 cycles.

Your rechargeable battery will last between 1 and 5 years. The main advantage of solar lights: they are maintenance-free. When choosing the most durable battery you can keep your solar light untouched for years.

Self-discharge Rate

This is the storage capacity loss of your battery when stocked.

Most of the manufacturers sell their batteries by pack, from 4 pieces to 24 or more. Therefore, you might not use all your batteries at once. In that case, the self-discharge rate is very important.

It can vary between 10% (for NiCd) and less than 1% (for NiMH) per month. The most efficient batteries can be stored for years without damaging their storage capacity.

Temperature Tolerance

Your solar lights will be exposed to the outdoors with steep variation of temperature during the day and depending on the season. Some batteries will malfunction when exposed to low temperature. In general, NiCd technology is the best.


Last but not least, we have selected solar light batteries offering the best ratio durability vs price, from less than $1 to $4 per unit. Manufacturers often offer huge rebates when batteries are bought in packs.

Now that you know how to choose your solar light batteries, let’s have a closer look at how they fit in your solar light.

How to Replace Your Solar Light Batteries in Eight Steps

You now have in hand your new solar light batteries. The replacement process is very important as you don’t want to ruin the water and dustproof properties of your solar light.

We have summarized below the replacement process in eight easy steps.

Step 1– Charge Your Solar Light Batteries

To avail the full capacity of your solar light batteries, they must be fully charged before installation.

Step 2 – Bring Your Solar Light Indoors

Your solar lights are made to work outdoors. Most of them are certified IP67, which means they have protection against dust and rain. Therefore, before removing the battery protection cap, you have to be in a dry environment. Thus, having them inside your house is best.

Step 3 – Remove the Battery Cap

You might need to unscrew the battery cap which is usually located on top of your solar light. Consult your user manual for the location of the battery compartment. Likewise, be sure to keep all the screws and joints in a safe place to put them back after the process.

Step 4 – Switch Off Your Solar Light

Turn off your solar light to avoid any electrical damage when changing the rechargeable batteries. Usually the switch is inside the battery compartment.

Step 5 – Install the New Solar Light Batteries

Remove the old batteries, and replace them by your new solar light batteries (fully charged).

Step 6 – Put Back the Battery Cap

Be sure that the battery cap is well screwed to avoid humidity to enter the compartment.

Step 7 – Turn On the Light for Testing

Test your solar light in a dark room. That will trigger the light sensor, and the LED light will shine.

Step 8 – Properly Dispose Your Used Solar Light Batteries

Do not throw your old batteries in the regular trash because they contain highly toxic material. You will find specific bins for used batteries. They will be sorted and dismantled, and some parts will be recycled. Protect the environment with this simple gesture.
