Replacement battery for Grandstream cordless phones

This Cameron & Co DS-CS-GWP820CL lithium-ion pack is built for the Grandstream DP730 and WP820 handsets. It replaces the original GS-01 cell and arrives in new condition with full OEM compatibility. The black unit ships as a single piece.

Voltage and capacity define the runtime envelope

The cell delivers 3.7 V and 1200 mAh for a total of 4.44 Wh. Talk time and standby duration follow the limits set by that energy figure and the handset's own power draw. No higher-capacity alternative is offered in this form factor.

Fits the DP730 and WP820.

The 56.80 x 35.94 x 5.43 mm footprint matches the factory battery compartment exactly. Phones outside the listed compatibility list will not accept this pack. Buyers who need a second spare or a different voltage should look elsewhere.

Questions about this item

Should I choose the 1200 mAh version or a different capacity for my Grandstream DP730?

This model supplies 1200 mAh at 3.7 V, matching the original GS-01 specification for the DP730 and WP820 handsets.

What does the 1200 mAh rating mean for daily talk time on the WP820?

The 1.2 Ah capacity delivers the same energy as the factory pack, so standby and talk times match the original battery performance.

Does the battery use a proprietary connector or a standard interface for the DP730?

It fits the DP730 and WP820 directly with the same connector layout as the GS-01 part, requiring no adapter or modification.
