How to use the battery of the camera?

Lithium batteries are common now, but Ni-MH and Ni-Cd are rare. At present, it is not necessary to charge all batteries, and the charging time should not be too long. Otherwise, it is easy to damage the battery chip. It is best to charge it when it shows that the battery is low. If it is a new battery, you really need to discharge the remaining power in the first few times. Otherwise, although there will be no memory effect, your battery can only work normally if it is charged and discharged more times.
