All products by Allsop Home & Garden contain one or more rechargeable batteries located inside the solar housing compartment. To change the batteries, locate the screws on the underside of the solar housing compartment. Unscrew the screws and separate the two halves of the solar housing compartment. Remove the old battery and replace it with a new rechargeable battery. Insert the screws back into their holes and screw the two halves of the solar housing compartment back to together securely.
