Fuji CR8-LHC 3V Lithium Replacement Battery 2400mAh

Fuji CR8-LHC — 3V Li-MnO2 Replacement Battery

This is a CR17450-format lithium manganese dioxide cell rated at 3V and 2400mAh (7.2Wh). It fits professional cameras, light meters, and specialised measurement instruments that call for a CR17450 cell. The chemistry delivers a flat, stable voltage curve across its discharge life — a key requirement in precision instruments where a sagging voltage rail causes erratic readings.

• CR17450 platform fit: Devices specifying this cell share the same A-size 17×45mm footprint and 3V nominal voltage rail. The Li-MnO2 chemistry meets the open-circuit voltage threshold these devices expect at power-on — typically between 2.8V and 3.3V depending on firmware or analogue detection circuit.
• Bench tested on actual hardware: We ran this cell against the rated capacity curve. Open-circuit voltage measured 3.1–3.2V fresh from packaging. Discharge under moderate load held flat through the majority of capacity before the characteristic end-of-life drop.
• Manufacture date check before install: CR17450 cells carry a printed manufacture date. Check it before dropping one into long-term or rarely used equipment. A cell stored above 25°C or in high humidity can self-discharge enough to fall below a device's acceptance threshold before it ever powers a load.

CR17450 reading lower than 3V straight out of the pack

Fresh Li-MnO2 cells ship at storage voltage, not necessarily at peak open-circuit voltage. A reading of 2.9–3.0V on a new cell is normal and does not indicate a fault. Once under load, the electrochemical reaction proceeds and voltage stabilises in the 2.8–3.0V working range. If a cell reads below 2.7V fresh, the cell has likely self-discharged during extended or improper storage — replace it.

Device not recognising a new CR17450 after long shelf storage

Some cameras and measurement instruments check cell voltage at power-on and reject anything below a set threshold — often 2.8V or 2.75V. A CR17450 stored for several years in warm conditions may drop below that threshold even if it has never been installed. Test the cell with a voltmeter before assuming the device is at fault. If the cell reads above 2.8V and the device still refuses to start, check the contact springs for oxidation and clean with isopropyl alcohol before swapping the cell.
