Siemens Simatic S5 Batteries

To protect your applications, backup batteries should be maintained to ensure that they are working. Classic Automation provides new batteries for many Siemens S5 and S7 systems.

In some cases the older Siemens Simatic S5 battery part number has been replaced with an equivalent Siemens Simatic S7 battery. In cases were Siemens no longer sells an equivalent, Classic Automation provides a replacement battery that is 100% backward compatible and uses the latest battery technology. Using these modern replacements is a better solution than using batteries with old date codes. 

Please contact us to purchase your Siemens Simatic S5 batteries.
