Our lithium ion batteries do not ship fully charged and thus, if not charged or used shortly after arrival, it may enter a "deep sleep" mode to conserve its overall lifespan. If your PowerShift battery isn't charging up or functioning properly, please attempt the following steps to troubleshoot the battery from its "deep sleep" mode:
1. Hold down LED indication light on the battery.
2. Attach battery to charger, disconnect and repeat (3-4 times if necessary).
3. The charger will light up with a single green light while it begins to charge.
4. Once the green lights on the charger begin cycling, the battery is charging normally.
With any further questions or persistent issues, please contact our support team via chat or email (firstname.lastname@example.org).
