Direct replacement for Tecra S1 models

This Cameron & Co CMOS battery matches part number V000010510 and fits Tecra S1 PT831L TE2000 TE2100 TE2200 TE2300 laptops. It restores the real-time clock and BIOS settings when the original cell is exhausted. The lithium chemistry delivers 3.0V and 40mAh capacity in a green package.

Fits the motherboard coin-cell socket

The cell measures 19.43 x 12.88 x 3.10 mm and slots into the existing holder without soldering or adapters. No external cables or chargers are required because the battery is non-rechargeable and powered solely by the board. Installation frees the system from date resets and CMOS checksum errors.

Holds settings for typical service intervals

Rated at 0.04 Ah and 0.12 Wh, the cell maintains configuration data for years under normal standby current. It cannot power the main system or drive any peripherals. Builders needing a rechargeable pack or higher capacity for other roles must choose a different product type.
