Solar lights are powered by rechargeable batteries.
They charge during the day through solar panels on fixtures.
These batteries are designed to withstand a discharge of at least 1000 deep and light for at least 1000 Nights.
They are readily available and easy to replace.
You just have to open the compartments and put them in.
The preferred battery for Solar lamps is nickel batteries (NiCd)
Or nickel (niMH).
They prefer because they are easy to charge and do not fully drain on a typical night.
The NiCd battery is very durable and reliable.
Fast charging with a typical battery charger to quickly restore power.
They can also be charged slowly, making it an ideal candidate for charging with solar panels on solar lights.
The NiCd battery should not be used for a short period of time and then charged.
This leads to the formation of crystals inside the battery, thus reducing the performance of the battery.
This is the so-called \"memory effect \".
The NiHM battery is the next level product of the NiCd battery.
They cost a little bit more but provide up to 40% of the running time.
NiMH\'s biggest advantage over NiCd is their ability to accept charging at any time without suffering from the \"memory effect.
These can also be charged quickly or slowly, making them a good candidate power supply for solar lights.
It is said that when you get the battery for the first time, you need to run the battery at least 3 full charge/discharge cycles before putting it into normal service.
This will help to get the maximum capacity of the battery.
For the solar lights, you can turn them off in the morning in the sunny place, and by the end of the night they will serve.
