ReplacementBatteryfortheMaxellER6#4AX-3.6V2600mAhLithium

This is a 3.6 V 2600 mAh lithium thionyl chloride (Li-SOCl2) direct-replacement backup battery for the Maxell ER6#4AX. It protects stored programs, RAM contents, and real-time clock data in industrial control systems, and is built as a form-fit-function replacement for the original memory-backup cell, so it installs without rewiring, reprogramming, or controller reconfiguration.

This battery cross-references to Maxell 5088286, Maxell ER6#4AX, Saft LS14500 AX, Saft LS14500CNA, and generic ER14505-AX. Match your existing battery by part number or by the equipment it powers to confirm fit. The cell offers high energy density, very low self-discharge, a long shelf life, and a stable 3.6 V output over its service life, so memory and clock data stay protected during power outages and extended shutdowns. Replace memory-backup batteries on a preventive schedule, and follow the equipment manufacturer's procedure so backed-up data is not lost during the swap.
