Note: This is a non-rechargeable primary battery (unless specifically marked as rechargeable by the manufacturer). It is intended for low-current electronic devices. Do not attempt to recharge a standard zinc-carbon or alkaline 9V battery. Store the battery in a cool, dry place and remove it from devices during long periods of non-use to help prevent leakage.
