This Cameron & Co DS-CS-DEM133BU is a non-rechargeable lithium CMOS battery rated at 3.0V and 200mAh. It replaces Dell part numbers 23.22056.001 and CB28.

Fits Inspiron, Vostro and XPS Models

The battery fits Dell Inspiron 1270, 1271, 1318, 1520, 1521, 1720 and 1721 chassis as well as Vostro 1400, 1500 and XPS M1330, M1340 and 1318 systems. Installation requires access to the motherboard header; no soldering or additional cabling is needed. Once seated, it frees the main battery from keeping the real-time clock alive.
