Note: Connection other than indicated may result in permanent damage to the unit.

Recalibration:
SMBus Smart Batteries contain a microchip that monitors battery usage and tracks how much capacity is available from the pack. It is possible for this process to accumulate errors, however, due to temperature fluctuations, aging, self-discharge and other factors.

To keep the internal information as accurate as possible, it is occasionally necessary to run the pack through the calibration cycle. This involves fully charging the pack, completely discharging it, and then recharging it again. The charger performs these steps automatically when a re-calibration is initiated.

To re-calibrate a pack, place it in the left bay and push the red arrow located between the bays. This process can take 16 hours. Some packs do not have the capability to be recalibrated. The charger automatically senses this, and simply drops back into the normal charge mode.
