four Characters You Would possibly Want To Change Your Solar Batteries – – E / The Environmental Journal

Solar lights require a battery, solar system, controller, and LED lamp to function properly. Solar batteries store solar energy – a solar system or a small photovoltaic cell is responsible for capturing the sunlight during the daylight hours, and then the solar energy is converted into electrical energy. A “charge controller” ensures that the batteries are not overcharged, monitors the amount of light and switches the LED light on and off.

How do you know if you need to replace your solar batteries? Check the signs below that would ask you to replace your solar batteries.

  1. Solar lights are switched on with normal batteries

Red earth Energie explains how important good solar batteries are for the continuous lighting of your solar lights, even on cloudy days. This is why you need to regularly check the condition of your solar batteries. You can easily check if the solar rechargeable batteries are faulty by replacing them with regular or regular batteries.

If your solar light does not turn on as intended at night, but turns on when you put regular batteries in, the problem is not with the lightbulb or any other component of the light, but with the sun Batteries are defective or worn out.

Note: Pay close attention to the location of the solar light, as solar batteries will not charge properly in the shady area as they rely on solar energy to charge.

  1. The lighting does not return to normal after charging

After charging the solar batteries, the lighting of the solar lights should return to normal. If not, you will need to replace the solar batteries.

How to test the solar batteries:

  • Put the solar lights under the sun for a day or two. Remember that solar lights must be exposed to direct sunlight for at least four hours a day to effectively charge the solar batteries.
  • Check if the lighting of the solar lights is back to normal.
  • When the light is back to normal, it means that your solar panels did not receive enough sunlight and that there was no problem with the batteries.
  1. You did not take out the solar batteries

If you store solar lights during the winter months, you will need to remove the solar batteries to maintain their lifespan. Otherwise the batteries will die. If you've tried testing the solar lights with the old batteries and they don't work all day even after charging, you'll need to replace the old batteries.

How to replace old solar batteries with a new set:

  • Remove the defective batteries from the solar lights.
  • You need to take apart the solar light if you can't find a battery cover. You will usually see screws at the top or bottom of the lights that hold the batteries.
  • Once you have accessed the solar batteries, you can remove them and replace them with new ones.
  1. You tried using the batteries in other solar lights but they still don't work

If you don't have regular batteries, you can test the solar batteries by building them into working solar lights if you have two or more of them. Make sure the solar batteries are fully charged in the other solar light for several hours before testing. If the other solar light works with the newly charged old solar batteries, the initial solar light may be faulty. There are other problems related to that solar power and lighting that solar lights create so the batteries aren't always the culprits.

Choose the best rechargeable solar batteries

How many batteries do you need for your solar garden lights to work? Typically, solar lights need one to four batteries to work. The two types of solar batteries commonly used in solar garden lights include: AA 1.2V / 1000 to 2000 mA nickel metal hydride (NiMH); and AA-size nickel cadmium (NiCad) 1.2 V / 500 to 900 mA.

Find out about the following benefits of various rechargeable solar batteries:

  • Nickel-Metal Hydride (NiMH) batteries: They have up to three times more charge capacity than nickel-cadmium (NiCd) batteries. That means they last longer and are more reliable. Also, NiMH batteries are better than NiCad because they are more environmentally friendly and can withstand higher temperatures. Even on cloudy days, NiMH continues to charge and its performance is not affected even with partial charges without the sun.
  • Nickel-Cadmium (NiCad) batteries: They are cheaper than NiMH batteries.


The performance of solar batteries can be affected by the charging time of the solar batteries, the amount of sunlight available, and the life of the batteries. Tests are required to determine whether the solar batteries are actually faulty or just improperly charged.
