* If you happen to leave your battery pack to go through an extended period of self-discharge, say more
than three months, the battery voltage level will become too low and needs to be Pre-Charged (to bring the
battery voltage level high enough) before it automatically resumes its normal Fast Charge. Pre-Charge may
take 30 minutes. Fast Charge usually takes 2~3 hours.
