MadSci Network: Chemistry |
Drew,
According to Energizer, they recommend using rechargable batteries "if a device either moves or makes noise and has a high drain rate".
As to which battery lasts longer, it would depend on how it was being used. It also would depend on how long the battery sat on the shelf before you bought it.
