Stop buying batteries! Throw these in a drawer and never be frustrated that the remote doesn't work, child's toy needs batteries etc. These batteries charge in a few hours! I use them in an Xbox controller. They last for weeks on a single charge. Also good for wireless mouse or keyboard, battery operated clocks or kitchen scales, bike lights, camping lights, camera or flash etc. Better than Nimh types as these are good for 3000 charges and they are rated at 1.5 volts not 1.2 Volts.
