Archos 101 Core 3G Replacement Battery 3.7V 5000mAh

Archos 101 Core 3G — 3.7V Li-Polymer Replacement Battery (AHB3097140)

This is a 3.7V, 5000mAh Li-Polymer battery that fits the Archos 101 Core 3G tablet and its AC101ASWFV2, AC101CR3GV2, and AC101CR3GV4 variants. It replaces the original AHB3097140 cell when the existing battery no longer holds a usable charge. Dimensions are 132.80 x 93.50 x 3.70mm — verify against your existing cell before installation.

• 101 Core 3G variant coverage: The AC101ASWFV2, AC101CR3GV2, and AC101CR3GV4 all share the same connector pinout, cell footprint, and BMS handshake protocol — that is why one cell covers all three board revisions without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the 101 Core 3G platform. The BMS accepted the cell without fault flags, voltage regulation held steady across display-on and WiFi-active load states, and charge termination triggered cleanly at 4.2V.
• Fuel gauge recalibration after swap: After installing this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This recalibrates the fuel gauge IC against the new cell's actual capacity curve and corrects the inaccurate percentage readings that commonly appear following a battery swap.

Archos 101 Core 3G shutting down at 15–25% remaining

This happens because the fuel gauge IC was calibrated to the old, degraded cell. Its voltage-to-capacity curve no longer maps correctly to the new cell, so the OS triggers a shutdown well before the battery is actually empty. The combined load of the display and active WiFi creates a brief voltage sag that the miscalibrated gauge reads as a critically low state. Run one full discharge to automatic shutoff and one uninterrupted charge to 100% — this resets the calibration reference and the premature shutdowns stop.

Fast charging not available after battery replacement on the 101 Core 3G

The charge IC on this tablet negotiates charging parameters during the first accepted charge cycle after a new cell is installed. Until that cycle completes, the device may fall back to standard 5V charging and not engage higher-rate input. This is not a fault with the replacement cell. Charge the tablet from 0% to 100% in a single uninterrupted session using the original Archos charger — after that cycle completes, fast charge negotiation resumes normally at the correct voltage.
