About this replacement
VeriFone Sapphire Console — 7.2V Ni-MH Replacement Battery (22024-01)
This 7.2V 3000mAh Ni-MH battery replaces part number 22024-01 in the VeriFone Sapphire point-of-sale console. The Sapphire is a merchant payment terminal used to process credit and debit card transactions. When the original cell degrades, the terminal loses the ability to sustain power through a full business day.
- Sapphire console fitment: The Sapphire uses a 7.2V Ni-MH pack with a specific connector and BMS handshake tied to the terminal's charge management IC. This replacement matches that voltage rail and connector pinout so the terminal's charge controller recognises the pack correctly on first boot.
- Bench tested on actual hardware: We cycled this pack through the Sapphire's charge and discharge sequence. The BMS accepted the handshake without error flags, and the charge IC moved through conditioning, bulk, and top-off phases as expected on a fresh Ni-MH cell.
- First-cycle calibration on the Sapphire: Complete one full transaction cycle before deploying in a live environment. The terminal maps battery capacity during normal operation and requires at least one complete power cycle to calibrate the charge indicator correctly.
Terminal not completing PCI boot sequence after battery swap
The Sapphire runs a PCI security boot check during startup. On a fresh Ni-MH cell, the BMS handshake may not be fully accepted until the pack completes one charge cycle. If the terminal stalls or loops during the boot sequence immediately after installation, this is the most likely cause. Allow the terminal to complete a full charge from mains power before attempting to boot on battery alone.
Sapphire battery indicator stuck at 99% after first charge
New Ni-MH cells arrive partially charged from storage. The Sapphire's charge IC enters top-off mode when it detects a cell already above a low threshold, which can cause the indicator to sit at 99% for an extended period. This is normal behaviour — the IC is topping off the cell, not stalled. Once the pack reaches full charge and the IC exits top-off mode, the indicator updates. If it remains static past four hours on mains, check that the terminal is not in a warm environment above 35°C, as thermal limits will pause the top-off phase.
