regardless if it is fully empty or still with some residual power.
If storing battery for a long time, the power level becomes very low caused by
self-discharging and the battery may be degraded. Be sure to recharge the battery at
least every 2 months even when not in use.
It is possible that the battery could not be fully charged, if moving the battery from a
cold place (<5°C) to a warm place (around 20°C) and then immediately charging it. In
this case, make sure battery is in the new environment for a short while to equalize the
temperature, then charge the battery.
When charging battery, the room temperature must be in the range of 5 - 40°C.
For recharging the Battery, insert the Battery pack squarely into the slot of the
recharger. If the battery pack sits in the recharger at an angle, the battery may not

replace into the recharger taking care to seat it correctly.
