Cameron & Co DS-CS-DEM660BU CMOS battery 3.0V 200mAh green

DELL Latitude CMOS replacement

This 3.0 V 200 mAh lithium cell replaces the original CMOS battery in several Latitude and Precision notebooks. It matches part numbers 077-A00, 0MR652, 313-020, 313-032, GC02001DR0, MR652 and VLT151-1BH. The green pack measures 25.20 x 20.32 x 4.80 mm and supplies 0.60 Wh. It is a non-rechargeable primary cell intended for real-time clock backup.

Non-rechargeable lithium limitation

Because the chemistry is primary lithium, the cell cannot be recharged by the laptop and must be swapped once depleted. It delivers a fixed 3.0 V output with 0.2 Ah capacity, so runtime depends entirely on the motherboard's standby current draw. No charging circuit or smart-fuel gauge is present, and the battery will not report health data to the operating system.

Solder-lead mounting and colour code

The unit ships with pre-attached leads for direct board connection, eliminating the need for a separate holder. Its green casing provides instant visual identification inside a crowded chassis. The compact 25.20 x 20.32 mm footprint fits the original battery cavity in the listed Latitude E6320, E6420, E6430, E6520, E7240, X1, Precision M4600 and M6600 models. Buyers needing a rechargeable CMOS solution or a different voltage should look elsewhere.
