To attain maximum battery life, procedures to maintain batteries must be followed.

The following changes are now available for the products within the listed serial numbers.

The reference below details the correct procedure for maintaining battery life and specifies the correct charging voltages.

Refer to Special Instruction, SEHS7633, "Battery Test Procedure".

Note: Failure to follow this recommendation can result in less than optimum product performance and reduced service life of the battery.
