There are generally two types of devices that take AA batteries:
1. Devices that use up power quickly (e.g. Cams, GameBoys, MLFBs)
2. Devices that use up small amounts of power (e.g. remote controls)
These batteries are for devices that use up power quickly. And they are excellent batteries: regarded as the best in a number of camps.
If you need batteries for low-power devices like remote controls, these are not the batteries you should be using. You want batteries that are designed to hold onto their charge (e.g. Sanyo Eneloop
) rather than batteries designed to be able to supply high-power.
Be sure to pick the right type of battery for your device. Batteries designed to supply high-power will typically not hold on to their charge as long as batteries designed for low-power devices.
