Actionpro X7 Replacement Battery 3.7V 1300mAh 083443A

Actionpro X7 / ISAW Series — 3.7V Li-ion Replacement Battery (083443A)

This 3.7V, 1300mAh (4.81Wh) lithium-ion cell replaces the OEM 083443A battery. It fits the Actionpro X7, ISAW A1, ISAW A2 Ace, and ISAW A3 action cameras. Physical dimensions are 47.20 × 36.08 × 8.50mm — confirm these against your existing cell before ordering.

• X7 and ISAW platform compatibility: These four models share the same cell format, connector pinout, and 3.7V nominal voltage rail. The BMS on each body communicates with the cell over the same two-pin contact layout, so one cell covers all listed variants.
• Bench tested on actual hardware: We cycled this cell through the X7 body and monitored BMS acceptance, charge termination, and discharge behaviour under continuous 1080p recording load. The protection circuit triggered correctly at low-voltage cutoff with no false trips during normal operation.
• First-charge protocol for the ISAW BMS: Insert the cell and run a full charge cycle inside the camera body or OEM charger before shooting. Some ISAW bodies need that initial in-camera charge cycle to calibrate the battery-remaining indicator to the new cell's discharge curve.

Battery percentage jumping erratically on the X7 display after fitting a new cell

The X7's fuel gauge maps voltage thresholds to percentage steps. A new cell has a slightly different discharge curve than the depleted OEM unit the camera learned from, so the indicator can skip or stall at certain percentages. This is a calibration issue, not a cell fault. Run two or three full charge-discharge cycles through the camera body and the gauge will track more accurately. After the second cycle, check that the cell reads below 3.0V at reported empty — anything above that means the BMS cutoff is set tighter than the indicator expects.

Actionpro X7 showing dead battery icon immediately after inserting a charged replacement

This happens when the camera body hasn't completed a handshake with the new cell's protection circuit. The BMS enters a low-power state during shipping and the camera reads it as a dead or absent cell. Remove the battery, reinsert it firmly, then place the camera on charge via the OEM cable for at least 15 minutes before powering on. If the icon persists after that charge attempt, check the contact pins on the battery door — bent or dirty contacts cause the same symptom and cleaning with isopropyl alcohol usually resolves it.
