Replace Batteries In Outdoor Solar Lights How and When

Outdoor solar lights and solar garden lights use rechargeable batteries to keep the lights lit at night. Each solar light has a solar panel that charges the rechargeable batteries by the sun during the day.Then at night when there is no sun the light turns on automatically and lights all night until dawn when the sun comes up again.It then turns itself off to restart the process all over again to charge during the day and light at night.

Most solar garden and outdoor solar lights use AA or AAA 1.2 V/600 mAh Ni-Cad (nickel cadmium) rechargeable batteries and some solar lights now come with AA 1.2V/1000 mAh NiMH (nickel metal hydride) rechargeable batteries.

The recommendations are to replace the batteries with the size and type that they original come with for the solar lights to work properly. Meaning that if its a AA you use a AA, if it is a 1.2V you use a 1.2V, if it is a Ni-Cd, use a Ni-Cd, if it is a NiMh use a NiMh.

As far as the mAh (MilliAmp Hours) factor is concerned, the difference here is about how much "juice" or power it will hold and how long it takes to charge it. A 600mAh to a 700mAh is a difference of 100mAh meaning it will have 100 more mAh of charge before it will run out of "juice" or power. The difference in charging length with your solar light will be a 600mAh will take approx. 7.2 hrs to charge and a 700mAh will take about 8.4 to charge. This is important to know when figuring how much direct sun will the solar panel get to recharge the batteries fully.

The rechargeable batteries for solar lights can last up to two years.When you begin to notice that the lights are weaker in brightness, begin to flicker or will not stay on for very long, then it becomes necessary to replace the batteries.

Lamp styles of solar lights vary but most allow for easy battery replacement. The batteries are normally located right under the solar panel.

Below are instructions for 4 different lamp styles of solar lights with pictures.
