Canon LP-E10 EOS 1100D Replacement Battery 7.4V 1100mAh

Canon EOS 1100D / REBEL T3 / KISS X50 — 7.4V Li-ion Replacement Battery (LP-E10)

This is a 7.4V, 1100mAh Li-ion cell built to the LP-E10 spec, fitting the Canon EOS 1100D, EOS 1200D, REBEL T3, KISS X50, and compatible models in that lineup. It slots into the battery compartment in place of the original Canon LP-E10 and communicates with the camera's BMS over the same three-contact interface. Capacity is 1100mAh (8.14Wh), matching the original rated cell.

• EOS entry-level platform fit: The 1100D, 1200D, REBEL T3, and KISS X50 all share the LP-E10 form factor and three-pin BMS contact layout. The camera body reads cell authentication data through the centre contact — any cell that passes that handshake correctly will display charge state on the LCD.
• Bench tested on actual hardware: We cycled this cell in an EOS 1100D body and through a Canon LC-E10 charger. The BMS accepted the cell on first insertion, charge termination triggered correctly at 8.4V, and the battery indicator displayed remaining charge without error codes.
• First charge cycle on the 1100D: Run the first full charge through the LC-E10 charger or directly in the camera body via USB where supported — not a third-party charger. The 1100D's BMS maps its battery-remaining percentage against the cell's discharge curve during the first charge cycle, which sets accurate indicator readings for subsequent use.

Battery percentage jumping around on the EOS 1100D display

The 1100D uses a voltage-threshold system to estimate remaining capacity — it maps specific voltage points to percentage brackets on the LCD. A new third-party cell may have a slightly different discharge curve than the original Canon cell the camera was calibrated against. This causes the indicator to skip levels or read higher than actual early in a shoot, then drop quickly at the end. Running two to three full charge-discharge cycles through the OEM charger recalibrates the indicator mapping. After conditioning, the reading should stabilise within a few percentage points of actual remaining capacity.

Flash not fully recycling between shots on a new LP-E10 cell

The built-in flash on the 1100D draws a short high-current pulse to recharge its capacitor after each firing. Near the end of a cell's charge, internal resistance rises and the capacitor recharge slows — the camera may lag before allowing the next flash-assisted shot. This is not a fault with the cell; it is a predictable effect of voltage sag under capacitor recharge current at low state of charge. If recycling lag starts appearing consistently mid-shoot, check cell voltage with a meter — below 7.0V under load, swap to a fresh cell rather than continuing to stress the capacitor circuit.
