IGT S2000 Handheld Console Replacement Battery 3.6V 160mAh

IGT S2000 — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 160mAh Ni-MH rechargeable battery for the IGT S2000 gaming device. It replaces the original cell when the console fails to hold a charge or powers off unexpectedly. Dimensions are 24.60 × 18.20 × 18.80mm — match these against your existing cell before fitting.

• S2000 platform fit: The S2000 runs a single Ni-MH cell at 3.6V to power its onboard logic and memory retention. This cell matches that voltage rail and physical footprint, so the charge circuit sees the correct cell chemistry from the first cycle.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The charge IC accepted the cell without fault flags, and the BMS held the cutoff voltage at the expected threshold across repeated cycles.
• First-cycle calibration on the S2000: After fitting, run the console through one complete session to automatic low-power cutoff before recharging. The S2000's fuel gauge IC sets its empty reference point against the first full discharge — skipping this leaves the capacity readout poorly anchored to the new cell's actual curve.

S2000 fuel gauge jumping or reading full after a cell swap

The S2000 stores its discharge curve reference in memory tied to the original cell. When a new cell goes in, the fuel gauge IC is still reading against the old cell's profile. This causes the indicator to jump, read incorrectly, or sit at full even when the cell is part-discharged. One complete discharge-to-cutoff cycle forces the IC to reset its reference to the new cell's actual voltage curve. After that cycle, the gauge tracks accurately.

Console showing shorter play sessions than expected after replacement

Fresh Ni-MH cells do not deliver full rated capacity on the first charge. The cell's active material needs several charge-discharge cycles to reach its full electrochemical capacity — typically three to five cycles. During that break-in period, available capacity sits noticeably below the 160mAh rating. Run three full cycles without partial top-ups and measure session length again before assuming a fault with the cell.
