Replacement Battery for Snom

The Cameron & Co DS-CS-SMN390CL is a 3.7V 0.9 Ah lithium-ion battery designed for Snom M3, M9 and M9R series DECT handsets. It also fits Grandstream DP720 and DP750 models as well as Swisstone BBM 320, 320C and 620 units. The pack replaces original part numbers including 00001595 and 60020438.

Slim Black Pack with Standard Connector

The cell measures 53.13 x 33.96 x 4.77 mm and uses a black lithium-ion construction rated at 3.33 Wh. Its thin profile matches the original battery compartment so the handset sits flush in its charging cradle. The connector aligns with the factory socket for a secure fit without adapters.

Check Handset Model and Part Number Before Ordering

Verify that your device appears in the supported list such as Snom 1271, 2758 or Grandstream DP720. Confirm the original battery label shows a compatible part number like 02-109457 or CS-SMN390CL. This pack is not suitable for handsets outside the listed series or for devices requiring a different voltage or capacity.
