Aiptek mini PocketDV M1 3.7V 1050mAh Compatible Battery

Aiptek mini PocketDV M1 / 8900 / VideoSharier VS1 — 3.7V Li-ion Replacement Battery

This is a 3.7V 1050mAh Li-ion cell for the Aiptek mini PocketDV M1, mini PocketDV 8900, VideoSharier VS1, and PocketDV T290. It fits the slim chassis of these pocket camcorders and replaces the original cell when it no longer holds a charge. Capacity is sourced from product specification — 1050mAh (3.89Wh).

• Shared fit across the PocketDV line: These Aiptek models share the same 3.7V single-cell architecture, connector pinout, and physical form factor — 52.92 x 33.78 x 5.48mm. One cell spec covers the entire compact camcorder range listed.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS holds the cutoff voltage cleanly and does not trip on the low current draw typical of these pocket camcorders during video capture.
• First-install charge cycle on the PocketDV: Before shooting, run one full charge through the camera body itself rather than a standalone charger. Some Aiptek BMS firmware maps the battery-remaining indicator to a charge profile established during that first in-body cycle — skipping it can cause inaccurate level readouts throughout the cell's life.

Battery percentage jumping erratically on the PocketDV display

The PocketDV's fuel gauge maps voltage thresholds to percentage steps. A new Li-ion cell has a slightly different discharge curve at the beginning of its life compared to a aged OEM cell the firmware was calibrated against. This mismatch causes the indicator to skip levels or drop suddenly at certain voltage points. The fix is to complete two or three full discharge-and-charge cycles through the camera body. After conditioning, the indicator tracks against the cell's actual curve and stabilises — you should see steady, step-by-step drops rather than jumps.

Camera body getting warm under sustained video recording

The PocketDV M1 and related models run the image sensor, compression processor, and storage write simultaneously during video capture — all drawing from a single 3.7V cell. That combined load generates heat in the battery and the body housing together. This is normal operating behaviour, not a cell fault. If the body becomes hot enough to trigger an automatic shutdown, let the unit cool for several minutes before resuming recording, and check that the battery contacts are clean and seated fully — a high-resistance connection amplifies heat at the terminal.
