About this replacement
Camera 2CP4036 — 6V Li-MnO2 Replacement Battery (CR-P2)
This is a 6V, 1500mAh lithium manganese dioxide CR-P2 cell. It fits film cameras, rangefinders, and vintage flash systems that require the CR-P2 format. Cross-references include 223, DL223A, EL223AP, K223LA, 5024LC, VL223, and PC223A.
- CR-P2 format compatibility: All devices listed above share the same CR-P2 footprint, terminal layout, and 6V nominal requirement. The cell slots into the same battery compartment regardless of which part number the manufacturer printed on the door.
- Bench tested on actual hardware: We ran this cell against a film camera light meter and a flash charging circuit. Voltage held steady at 6V under light-meter draw and the flash capacitor charged without hesitation across multiple cycles.
- Terminal short risk in storage: Store CR-P2 cells away from loose coins, keys, or any metal surface. Both terminals are exposed on the same face of the cell. Contact with a conductive object across those terminals will silently drain the cell before it ever enters a camera.
Flash not cycling at full speed when shooting in cold conditions
Li-MnO2 cells lose available capacity as temperature drops — this is a chemistry-level behaviour, not a defect. At temperatures below 10°C, the cell's internal resistance rises, which slows current delivery to the flash capacitor. The flash still charges and fires, but recycle time extends noticeably. Warming the camera body between shots by keeping it inside a coat pocket restores normal cycle speed.
CR-P2 reading below 6V on a multimeter straight out of the packaging
An open-circuit voltage reading on a fresh CR-P2 can show 5.8–5.9V with no load applied — this is normal for Li-MnO2 chemistry at rest. The cell stabilises closer to its rated 6V once it sees actual current draw from the camera circuit. If the reading is below 5.5V with no load, the cell may have been drained in storage by terminal contact. Check the cell surface for marks, and test under load by inserting it into the camera and triggering the light meter.
