Why does a rechargeable NiMH battery lose charge in a digital camera?
Ni-MH batteries lose charge, or self-discharge, at a rate of one to two percent per day, whether they are installed in the camera or not. This means that if a battery is fully charged, after several weeks, the battery will be low or dead even if it was not installed in the camera or if it was installed in the camera but no pictures were taken. Ni-MH batteries are best for those who use the camera frequently and recharge often.
