Installation is a direct swap: open the battery compartment, disconnect the old pack and connect the new one using the existing connector. The physical dimensions are 50.79 x 42.4 x 14.23mm and the weight is 114.3g, so it seats in the same space without modification. Common issues arise only when the model number or part number does not match the device, leading to a connector or voltage mismatch. Verify the exact code before fitting.

Check Your Handset First

Before ordering, confirm that your device lists one of the compatible model numbers such as EXT1865, SPPA1071, EZI996, SPP-933, TRU348, SPP-SS960, BT800, FF950, CDU5160, EXT1760, FF5500, EXT1160 or SPPSS960. Also verify the battery part number BP-T18 or BP-T24 printed on the original pack. This battery is not for devices requiring a different voltage, chemistry or form factor.
