ASI AMATA EL80N Replacement Battery 11.1V 4400mAh

ASI AMATA EL80N / S96 Series — 11.1V Li-ion Replacement Battery

This is an 11.1V, 4400mAh (48.84Wh) lithium-ion battery for ASI AMATA notebooks across the EL80N, S96E, S96J, and S96S lines. It slots into the same bay as the factory cell and connects through the original multi-pin harness. Voltage and connector pinout match OEM spec across all four models.

• EL80N and S96 platform fit: These four models share the same 11.1V battery rail, physical form factor, and BMS communication protocol — which is why one cell covers all of them. The connector latch and tab spacing are identical across the EL80N and S96 variants.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the S96 platform and monitored BMS handshake across charge stages. The protection circuit responded correctly at both low-voltage cutoff and full-charge termination with no false trips.
• First cycle after install: After fitting this cell, run the laptop down to hibernate cutoff from a full charge — do not interrupt the discharge. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health or "unknown battery" warning that appears after swapping any cell in this platform.

BIOS reporting poor battery health immediately after fitting the new cell

The BIOS on ASI AMATA notebooks stores learned capacity data from the previous cell in EEPROM. When a new cell goes in, that stored data no longer matches the actual chemistry, so the firmware flags the battery as degraded or unhealthy. This is a firmware calibration gap — not a fault in the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% lets the BIOS re-learn the cell's actual capacity curve. After two to three cycles, the health indicator should settle at a normal reading.

This happens when the fuel gauge IC has not yet calibrated against the new cell — it miscalculates the remaining capacity and the system hits a hard shutoff before the display figure reaches zero. The root cause is a voltage cliff: under combined CPU and display load, the cell voltage drops faster than the uncalibrated gauge predicts. Force a full discharge to hibernate cutoff, then charge to 100% without interruption — repeat this two to three times. After calibration, the gauge will track the cell's actual voltage curve and the premature shutdowns will stop.
