Archos 43 Internet Tablet 3.7V Li-Polymer Replacement Battery

Archos 43 Internet Tablet — 3.7V Li-Polymer Replacement Battery (L04041200625)

This is a 3.7V, 1600mAh Li-Polymer replacement battery for the Archos 43 Internet Tablet (A43IT), including the 8GB and 16GB variants. It matches OEM part number L04041200625 and fits the same physical footprint at 65.06 × 49.72 × 4.56mm. If your Archos 43 no longer holds a charge through a full media session, this cell replaces the degraded original.

• A43IT model family: The 8GB and 16GB variants of the A43IT share an identical battery bay, connector, and BMS handshake. One cell covers all of them — no variant-specific wiring differences to account for.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the A43IT platform. The BMS accepted charge current normally, held the 3.7V nominal rail steady during video playback, and triggered the low-voltage cutoff at the correct threshold without false trips.
• Post-installation charge cycle: After fitting a new cell, connect the Archos 43 to its charger before powering on. Media players frequently enter deep-discharge protection after extended storage — a slow trickle charge for 20–30 minutes primes the BMS to accept full charge current before the device will boot reliably.

Battery percentage jumping after a cell swap on the Archos 43

The A43IT reads state of charge through a voltage-threshold lookup table calibrated to the original cell's discharge curve. A fresh Li-Polymer cell has a slightly different open-circuit voltage profile at partial charge, so the indicator can jump — reporting 80% one moment and 55% the next. This settles after one or two full charge-to-discharge cycles, which recalibrates the lookup against the new cell's actual curve. Run the device down to auto-shutoff, then charge uninterrupted to 100% twice.

The audio amplifier in the A43IT draws a short current spike when driving the speaker at higher volumes. Near the end of a degraded cell's discharge curve, that spike pulls voltage below the BMS protection threshold and triggers a cutoff — even though the display still shows remaining charge. A fresh 1600mAh cell restores the voltage headroom the amplifier needs at end-of-discharge. If cutouts persist after fitting the new cell, check that the connector is fully seated — a loose contact creates the same resistive voltage drop.
