Direct Replacement Battery

The Beisite SP307 is a new lithium-ion battery built for the Siemens Simatic Programmer CNC System models 31CP8, 49 and 64-2. It restores mobile power to industrial programming units that have lost runtime through age or heavy field use. The pack ships ready to install with no configuration required.

Fixed Voltage And Capacity Limits

The cell chemistry delivers 11.55V at 90Wh and 7800mAh, so runtime is bounded by those ratings and cannot be extended without a larger pack. The unit only fits the listed Simatic systems; it will not power other laptops or CNC controllers. Charge cycles follow standard lithium-ion behaviour and degrade with time.

Replaces SP307 And 31CP8/49/64-2 Packs

This battery directly substitutes the original SP307 and 31CP8/49/64-2 part numbers when the original no longer holds a usable charge. The upgrade is worth it when downtime on the shop floor costs more than a single replacement. It does not add new features or increase capacity beyond the factory specification.
