Premier DS8330 3.7V Compatible Battery 1250mAh Li-ion

Premier DS8330 — 3.7V Li-ion Replacement Battery

This 3.7V, 1250mAh lithium-ion cell is a direct replacement for the Premier DS8330 digital camera battery. It restores full shooting capability when the original cell no longer holds a useful charge. Capacity figure is sourced from product data: 1250mAh (4.63Wh).

• DS8330 fit: The DS8330 uses a compact Li-ion cell on a single 3.7V rail. This replacement matches the original cell's voltage, physical footprint (41.95 × 36.05 × 9.80mm), and connector orientation — the camera's BMS reads it on the same charge and discharge thresholds as the factory cell.
• Bench tested on actual hardware: We cycled this cell through the DS8330 body using an OEM-compatible charger. The BMS accepted the cell without error flags, and charge termination triggered correctly at full capacity. Discharge tracking remained consistent across multiple cycles.
• First-cycle acceptance on the DS8330: Run the first full charge cycle inside the camera body or with an OEM-compatible charger. Some compact camera BMS systems will not calibrate the battery-remaining indicator accurately until they complete one supervised charge cycle from within the body itself.

Battery percentage jumping on the DS8330 display after fitting a new cell

The DS8330's charge indicator maps voltage thresholds to percentage steps. A new Li-ion cell has a slightly different discharge curve shape at the start of its life compared to a worn original cell — the camera's indicator was calibrated against the aged curve. This causes the percentage to jump or stall at certain points, typically between 80% and 60%. After two or three full charge-discharge cycles, the indicator stabilises and tracks the new cell's curve correctly.

This happens when the BMS has not completed an initial handshake with the new cell. Remove the battery, wait ten seconds, and reinsert it. If the dead battery icon persists, place the cell back into the charger until the charge LED confirms full charge — typically ending at 4.2V on a standard Li-ion charge cycle. Reinsert into the camera body; in most cases the indicator clears on the next power-on.
