Factors to Consider:

solar lights batteries

It is important to consider several factors before purchasing rechargeable solar light batteries. Here are some of them:


There are three main types of rechargeable batteries: Nickel Metal Hydride (NiMH), Lithium Ion (Li-ion), and Nickel Cadmium (NiCd). Each type has its benefits and drawbacks.

NiMH batteries are very popular rechargeable battery options, because they can retain up to 70% of their charge after one month. They are also inexpensive to operate, maintain good voltage performance over the lifespan of the battery, and can handle high discharge rates without significant voltage loss. 

NiMH batteries can be recycled without harm to the environment and are safe for disposal in landfills.

NiCd batteries are durable and can be discharged down to 20% of their capacity without damage. They also offer good load capabilities, maintain consistent voltage levels during discharge, and have a longer lifespan than NiMH batteries. 

However, they are not as environmentally-friendly as NiMH and require special disposal.

Li-ion batteries can provide a high voltage output, good load capabilities, and have a long lifespan. They are also very safe for disposal in landfills and can be recycled without fear of environmental harm. 

Despite this, they are much more expensive than NiMH and NiCd batteries to purchase, require a larger circuit board to handle high loads, and have a shorter lifespan than NiMH.

Battery Life:

The life of the battery also depends on how often it is used. If you want your lights to last for a few hours, then you should only use them for short periods at time. The more often they are used, the less battery life they have left. 

Alternatively, you should choose a battery that has more battery capacity than others to get long periods of uninterrupted charge.  


The best batteries are built in such a way that they possess the ability to recharge themselves at any time of the day, even during overcast days. It should have an efficient design that ensures that it is always ready to go when you are. Also, the quality of the materials used to build it is important.

Voltage Rating:

Energizer Rechargeable Batteries

The quality of the solar batteries and lights can vary greatly depending on the manufacturer brand. Keep in mind that the better but expensive solar lights will last longer, but the less expensive ones will work just fine.


The price of the batteries can vary greatly, which is why it doesn’t always make sense to buy the cheapest product. It is important to compare all of your options before you make your purchase.


Be sure to check which type of battery is needed before you buy your lights. Some need regular alkaline batteries (a.k.a. disposable), while others require chemical or lead-acid ones (a.k.a. rechargeable).


Before you buy, check if the unit is weather-resistant. It needs to be able to withstand rain and snow, as well as the strong winds that might come through your area.


Check to make sure the batteries are compatible with your lights. Some brands might use a different size or type of battery than others, which can cause problems.
