Battery Life Solar Battery Chargers do not require any maintenance. Do not attempt to open or repair the battery charger as it will invalidate the limited warranty. A damp cloth may be used to clean dust, dirt, or other debris off of the battery charger. Anything that would inhibit sunlight from reaching the solar cells should be removed.
