Replacement Battery for Ascom Handsets

This Cameron Sino IP73 cell phone battery replaces the original Ascom 490933A and 660497 packs used in D63, DECT 3735, DH7 and i63 cordless phones. It delivers 800mAh capacity at 3.7V for 2.96Wh of energy. The fully decoded chip communicates with the handset exactly like the factory unit.

Sustained Talk and Standby Time

Under continuous use the lithium-ion cell maintains stable voltage throughout the discharge curve, avoiding the sudden drops seen with aged packs. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuit during long charging cycles. Performance settles after 2 or 3 complete charge and discharge cycles.

Compatibility Check Before Ordering

Verify the model number on your handset and the part number printed on your existing battery match the Ascom models listed above. Confirm the connector orientation lines up with the socket before fitting. Avoid low-quality third-party chargers as they can reduce the service life of the new cell.

Questions about this item

How much heat does the 3.7 V lithium-ion cell produce during a full day of DECT handset use?

The 800 mAh cell is designed for cordless phones and generates only modest warmth during typical talk and standby cycles; the built-in protection circuit prevents excessive temperature rise.

Which original Ascom part numbers must match for this IP73 pack to fit my handset?

Verify that your current battery carries Ascom 490933A or 660497; the replacement is built to those exact specifications.

Will the 79.72 × 47.16 × 10.30 mm dimensions and connector align with an older Ascom D63 or DECT 3735 handset?

Yes — the pack mirrors the original footprint and connector layout for D63, DECT 3735, DH7 and i63 models, so it slots in without modification.
