Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been
used for an extended period is not activated, the electric discharge might be low when
using them the first and second time. This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
