Common to lead acid batteries, your PowerTank‘s charge needs to be kept topped up. It is important to recharge your PowerTank after each period of use. Allowing the battery to discharge power over several periods of use, and not re-charging regularly can lead to the condition where the battery can not be charged with the supplied charger. The battery must also be charged before, and regularly during, periods of storage. In many cases, the battery can be rescued by the use of a deep charger, however, if the battery is allowed to discharge completely, and then not charged for a lengthy period, it may become impossible to re-charge at all.
If in doubt, always recharge your Powertank after each period of use. Please refer to the PowerTank instructions for instructions on maintaining your PowerTank.
