About this replacement
Acer Aspire 1700 / 1710 — 14.4V Li-ion Replacement Battery (916-2350)
This is a 14.4V, 4400mAh (63.36Wh) Li-ion replacement battery for the Acer Aspire 1700 and Aspire 1710 notebooks. It replaces OEM part numbers 916-2350, BT.A0807.002, and SQU-207. When the original cell degrades and no longer sustains a charge, this unit restores full unplugged operation.
- Aspire 1700 and 1710 compatibility: Both models run the same 14.4V battery rail and use an identical connector and BMS handshake protocol, so one cell covers the full platform without modification.
- Bench tested on actual hardware: We cycled this cell through full charge and load discharge on the Aspire 1700 platform. The BMS communicated correctly with the BIOS, reported state-of-charge accurately, and held voltage without sagging under combined CPU and display load.
- Post-install calibration for the Aspire 1700: After fitting, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after fitting the new cell
The Aspire 1700 BIOS stores charge history and health data from the previous cell in its battery learn table. When a new cell goes in, that stale data makes the system flag poor health before it has any real readings. This is not a fault with the replacement cell. One complete discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rebuild its learn table against the new cell's actual chemistry and clear the warning.
Aspire 1700 shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The IC is still using parameters from the old degraded cell, so it misreads remaining capacity and the laptop cuts out before the gauge reaches zero. It is not a hardware fault — it corrects itself over two or three full charge and discharge cycles as the IC maps the new cell's actual voltage profile. If shutdowns persist after three cycles, check that the BIOS is not capping the charge threshold, which should read 100% under Power Management settings.
