Bell & Howell DNV900HD Compatible Battery 3.7V 1100mAh

Bell & Howell DNV900HD — 3.7V Li-ion Replacement Battery

This 3.7V 1100mAh Li-ion cell replaces the original battery in the Bell & Howell DNV900HD digital camcorder. It fits the DNV900HD body directly and restores power for recording and playback. Capacity is 1100mAh (4.07Wh) — matching the original specification.

• DNV900HD compatibility: The DNV900HD uses a compact 3.7V single-cell Li-ion pack with a low-current draw profile typical of entry-level digital camcorders. This replacement matches that voltage rail and form factor — 38.25 × 38.15 × 9.50mm — so it seats and latches correctly in the battery compartment.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a 3.7V Li-ion platform and confirmed the BMS holds the cutoff voltage at the expected low-end threshold without premature shutoff under normal camcorder load.
• First charge cycle on the DNV900HD: Insert the battery and charge it fully inside the camera body before your first recording session. Some compact camcorder BMS implementations need one complete in-body charge cycle to map the new cell's discharge curve accurately — skipping this can cause the battery indicator to read incorrectly from the start.

Why the DNV900HD battery indicator reads incorrectly after fitting a new cell

The DNV900HD maps its battery-remaining display against a stored discharge curve from the previous cell. A new cell has a slightly different voltage-to-capacity profile, so the indicator can show full bars and then drop suddenly, or report low charge when usable capacity remains. Running one full charge-to-discharge cycle inside the camera body lets the firmware recalibrate against the new cell's actual curve. After that cycle, the indicator tracks remaining charge accurately.

If the camera shows a dead battery icon or won't start with a freshly installed replacement, the cell voltage may have dropped below the camera's minimum startup threshold during storage. Charge the battery in the camera body for at least 15 minutes before attempting to power on. If the camera body won't initiate charging from a deeply discharged cell, an external 3.7V Li-ion charger can bring the cell above 3.0V, at which point the camera body will accept it for a full charge cycle.
