Kyocera BP-1100 MICROELITE 3300 Replacement Battery 3.7V 2400mAh

Kyocera MICROELITE 3300 — 3.7V Li-ion Replacement Battery (BP-1100)

This is a 3.7V Li-ion replacement battery for the Kyocera MICROELITE 3300 compact point-and-shoot camera. It carries a 2400mAh (8.88Wh) capacity and uses the OEM part number BP-1100. If the original cell no longer holds a charge or the camera shuts down mid-use, this is the direct swap.

• MICROELITE 3300 fit: The BP-1100 cell format is matched to the MICROELITE 3300's battery compartment — same voltage rail, same connector orientation, same BMS communication spec. No modifications needed to seat and secure the cell.
• Bench tested on actual hardware: We cycled this battery through charge and discharge passes on compatible hardware. The BMS accepted the cell without rejection flags, held voltage across the discharge curve, and triggered cutoff at the correct low-voltage threshold.
• First-cycle initialisation on the MICROELITE 3300: Run the first full charge through the camera body or the OEM charger before heavy shooting. The MICROELITE 3300's battery gauge uses a full charge cycle to map the new cell's discharge curve — skipping this step causes the battery indicator to read inaccurately from the start.

Flash recycling slowing down before the battery indicator drops

The MICROELITE 3300's flash capacitor draws a concentrated burst of current each time it recharges between shots. Near the end of a cell's discharge cycle, internal resistance rises and the capacitor takes longer to reach full charge — even when the battery indicator still shows charge remaining. This is a cell-level voltage sag issue, not a flash unit fault. If recycle time noticeably increases but the battery icon still reads above half, the cell is closer to depletion than the indicator suggests. Return to charge before the next shooting session.

Battery percentage jumping erratically on the MICROELITE 3300 display

The camera maps its battery indicator to fixed voltage thresholds calibrated for the original cell's discharge curve. A new replacement cell discharges along a slightly different curve until the BMS has logged at least one full cycle. This mismatch causes the percentage readout to skip levels — jumping from 80% to 50%, or stalling at one level then dropping suddenly. The fix is straightforward: complete one full charge-to-depletion cycle, then recharge to 100% at 3.7V nominal. After that single calibration cycle, the indicator tracks accurately.
