Direct replacement for Siemens Simatic CNC

This new lithium-ion battery matches the SP307 and 31CP8/49/64-2 part numbers for Siemens Simatic programmer CNC systems. It delivers 11.55 volts and a 90Wh, 7800mAh capacity in a black housing. The pack is built to restore mobile power to the original industrial controller. It is not for users who need a different voltage or connector layout.

Swaps out the original SP307 pack when runtime drops

The unit replaces the factory battery carrying part numbers SP307 and 31CP8/49/64-2. The change is worth it when the existing cell no longer holds enough charge for a full shift or shows swelling. No other part numbers or chemistries are supported by this model. It is not for technicians servicing non-Simatic hardware or newer controller revisions with different pinouts.

Steady 11.55 V output through the full discharge

Lithium-ion chemistry maintains the rated voltage across the 90Wh capacity without the sharp sag seen in aged packs. The 7800mAh rating reflects sustained delivery rather than a brief peak. Performance stays consistent until the protection circuit cuts off at the safe lower limit. It is not for applications that demand hot-swap capability or redundant cell arrays.
