IGT AVP Gaming Console Replacement Battery 3.6V 2000mAh

IGT AVP — 3.6V Ni-MH Replacement Battery (CUSTOM-232)

This is a 3.6V, 2000mAh Ni-MH replacement battery for the IGT AVP handheld gaming unit. It fits directly in place of part numbers CUSTOM-232 and HRAAU-F3PC-4 REV. A. When the original cell degrades and the unit no longer holds a charge, this restores full function without replacing the console.

• AVP platform fit: The AVP uses a fixed-voltage Ni-MH cell with specific physical dimensions — 50.90 x 43.00 x 14.80mm — and a connector keyed to the OEM spec. This replacement matches both the electrical rating and the mechanical footprint, so the charge circuit sees the correct internal resistance profile from the first cycle.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the AVP platform. The BMS accepted the new cell without flagging an incompatible chemistry, and charge termination triggered correctly at full capacity.
• Fuel gauge calibration on first use: After installing this cell, run one complete play session to automatic cutoff before recharging. The AVP's fuel gauge IC sets its empty reference point against the first full discharge cycle — skipping this step causes the indicator to read inaccurately from the start.

Handheld console fuel gauge jumping after a cell swap

The AVP's fuel gauge IC builds its discharge model against the cell it was calibrated to. Swap in a fresh Ni-MH cell and the IC is now reading a different discharge curve — it produces erratic percentage jumps as a result. This is not a fault with the replacement cell. One full discharge cycle, run to automatic cutoff, forces the IC to re-anchor its empty reference to the new cell's actual voltage floor, and readings stabilise from the next charge onward.

AVP not charging the replacement cell at its full rate

The AVP charge IC applies a conservative current limit when it detects a cell with an unfamiliar charge history — a safety measure against overcharging an unknown state. This shows up as a slower-than-expected charge on the first one or two cycles. The IC relaxes the limit once it has completed a full charge-discharge reference cycle. If the unit still charges slowly after three full cycles, check that the battery contacts are fully seated and the terminal voltage at the connector reads at least 3.6V under no load.
