Frequently asked questions
Why won't my new solar Christmas lights turn on?
Check the switch and pull out any plastic tab between the battery and its contact, then cover the panel with your hand. Covering the sensor mimics night, so the lights should come on if the sensor works.
How often do solar light batteries need replacing?
A Gama Sonic maintenance article suggests replacing solar light batteries every 2.5 to 3 years, and Energizer gives NiMH cells a typical life of 2 to 5 years. A set that fades early even after sunny days often has a worn battery.
How do I get rid of old rechargeable batteries?
The EPA says rechargeable batteries should not go in household trash or municipal recycling bins. Tape the terminals and take them to a battery recycler, a retailer take-back program or household hazardous waste collection.
