Grundig LC-280 Replacement Battery 7.4V 2000mAh

Grundig LC-280 Series — 7.4V Li-ion Replacement Battery

This 7.4V 2000mAh Li-ion battery replaces the original cell in Grundig digital cameras including the LC-280, LC-380HE, LC-835E, and LC-855HE. It slots into the same battery compartment and connects to the same BMS contacts as the factory cell. Voltage and capacity match the OEM spec — 7.4V, 2000mAh (14.8Wh).

• LC-280 to LC-855HE compatibility: These Grundig camera models share the same battery form factor, voltage rail, and BMS contact layout. A single cell services the full range because the power delivery circuit is identical across this lineup — no adapter or modification needed.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles and confirmed BMS handshake with the camera body. The protection circuit responded correctly to end-of-discharge cutoff and charge termination without tripping prematurely.
• First-install charge cycle on Grundig bodies: On first use, charge the new cell fully through the camera body or OEM charger before shooting. Grundig BMS logic maps the battery-remaining display against a known charge curve — one complete charge cycle from inside the camera anchors that calibration and gives you accurate indicator readings from the first session onward.

Battery percentage jumping erratically on the LC-280 display

Grundig cameras map fuel-gauge readings against the OEM cell's discharge curve. A new third-party cell has a slightly different voltage-to-capacity slope, so the camera's indicator can jump — 80% to 55% in one shot, or stall at 20% for an extended session. This is a calibration issue, not a cell fault. Run two full charge-discharge cycles through the camera body and the indicator stabilises as the BMS learns the new cell's curve. After two cycles, the display should read within a few percent of actual remaining charge.

Flash not fully recycling between shots on a new cell

Flash recharge draws a sharp current spike from the battery to refill the capacitor bank. If the cell voltage has sagged — even on a replacement that reads as "full" — the capacitor takes longer to reach peak charge voltage, and consecutive flash shots come out underexposed. Check the cell's resting voltage with a multimeter: it should sit at or above 8.2V after a full charge on a 7.4V Li-ion cell. If it reads below 7.8V at rest post-charge, the cell is not reaching full capacity and needs to be replaced or re-cycled once more through a full OEM charger cycle.
