GE B9651T Lithium Battery – 3V Memory Backup Power Source

This lithium battery preserves user programs and critical system parameters. It serves as a direct replacement for GE CPU modules and motion controllers. You need this cell to prevent data loss during main power interruptions.

Key Technical Specifications

Physical Dimensions and Connector

This battery measures 14.5 mm in diameter and 5.0 mm in height. The cell weighs only 3.2 grams, adding negligible mass to your system. A pre-attached JST connector uses two pins with 150 mm flying leads. Consequently, you can plug this battery directly into compatible GE modules without soldering.

Chemical Composition and Energy Storage

The lithium metal chemistry delivers a stable 3.0V output across its entire life. A 950 mAh capacity stores enough energy for years of continuous backup duty. This cell will maintain CPU memory for approximately 24 months without external power. Therefore, your programs remain safe during extended plant shutdowns or maintenance periods.

Compatibility and Replacement Intervals

This battery fits IC200CPU001-DH, IC693CPU series, and many motion control modules. You should replace the cell every 24 months for guaranteed data retention. The module will trigger a low-battery alarm when voltage drops below 2.7V. Always dispose of used lithium cells according to local hazardous waste regulations.

Installation and Handling Precautions

Insert the JST connector firmly until you hear a positive click. Do not attempt to recharge this battery as it may leak or rupture. Store spare cells in a cool, dry place away from metal objects. Furthermore, keep the connector contacts clean to ensure reliable voltage delivery.
