Remote controls function for months if not years on practically dead batteries
1WARNING - I will NOT be held responsible for any damages the methods shown and described in this video may cause to yourself or someone else, including (but not limited to) material, moral, and/or corporeal damages. Any information you choose to put into use from this video is done AT YOUR OWN RISK. Battery acid can be very corrosive and can cause immediate harm to yourself and others around you, as well as damage to items and surfaces that come into contact with battery acid. NEVER leave a battery that is leaking or developing corrosion in an electronic device when said device is not in use, as the emitting battery acid can cause irreparable damage to your electronic device. If you or someone else comes into contact with battery acid, wash hands and the affected area immediately and dispose of the leaking batteries promptly.
Here is a simple money saving tip: when batteries become too weak to function in high-drain devices (such as MP3 players, digital cameras, video game controllers, etc.) chances are the 'drained' batteries still have plenty of power to power low-drain devices such as remote controllers (remote controls for such devices as televisions, DVD players, Blu-Ray disc players, VCRs, PVRs, home entertainment systems, sound systems, etc) giving them a lifespan of months if not years.
