RESET TYPE/LEVEL (AFTER OR DURING RECHARGE)
CTR = Charge Tracking Reset: If the gage is connected to the battery during recharge, the gage will
track the battery charge level.
OCR = Open Circuit Reset: If the gage is disconnected from the battery during recharge, the gage will
retain the last indication. It willadvance to full when reconnected only if the battery voltage is above the
OCR level. For standard (“B”) reset, OCR = 2.09 VPC (VPC = volts per cell.)
