Estry standard battery 3.0V 200mAh for DELL Latitude E4200 E4300 GC02000KG00

Replacement battery for Latitude E4200 and E4300

This 3.0 V lithium coin cell replaces the original GC02000KG00 part in Dell Latitude E4200 and E4300 systems. It supplies 200 mAh capacity and 0.6 Wh energy for CMOS memory and real-time clock backup. The pack is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Critical specification: 3.0 V and 200 mAh

The cell must deliver exactly 3.0 volts and 200 milliampere-hours; any deviation will prevent the laptop from retaining BIOS settings and system time when main power is removed. Matching both figures guarantees the motherboard recognises the battery and charges it correctly.

Sustained load behaviour

Under the continuous microampere draw of the CMOS circuit the voltage remains stable for the rated service life. Overcharge, over-discharge, over-voltage and short-circuit protection circuits prevent degradation during years of trickle-charge operation. The chemistry is not suited for high-current pulse loads or primary power roles.

Not for primary power or high-drain devices

Buyers who need a main system battery, a higher-capacity coin cell, or a rechargeable pack for portable equipment cannot use this part. It is designed solely as a low-current CMOS backup for the listed Latitude models.
