Replacement battery for Grandstream cordless phones

This Cameron Sino DP730 battery replaces the original GS-01 pack in Grandstream DP730 and WP820 handsets. It delivers 1200mAh capacity at 3.7V for 4.44Wh total energy. A fully decoded chip ensures the handset recognises the cell exactly like the factory unit. The pack weighs 25.0g and measures 56.80 x 35.94 x 5.43mm.

Capacity and practical runtime

The 1200mAh rating supports typical daily talk and standby cycles on a single charge. Heavy users who keep the handset off-hook for many hours may need a mid-day top-up. The lithium-ion chemistry maintains stable voltage until the protection circuit cuts off at the safe lower limit. Expect full performance after two or three complete charge and discharge cycles.

Compatibility decided by part number GS-01

The sole specification that determines fit is the Grandstream GS-01 part number printed on your original battery. If your handset uses a different part number this pack will not connect or lock into the compartment. Verify the model label on the device and the sticker on the old cell before ordering.
