Fits listed CTP models; not for other devices

Direct replacement for handsets using part numbers CTP9200, CTP8225, CTP8310, CTP8325, CTP8212 and CTP8210. Buyers whose equipment uses a different battery code or chemistry should look elsewhere. Confirm the exact model and part number before ordering to avoid mismatched voltage or connector layout.

3.6 V 600 mAh Ni-MH chemistry decides compatibility

Voltage and capacity must match the original specification exactly; a higher or lower rating will cause charging errors or reduced talk time. The Ni-MH chemistry also dictates the charge algorithm used by the handset base station. Verify that the device requires a 3.6 V 600 mAh nickel-metal-hydride pack before purchasing.
