Who It's For

This battery is best for owners of Microsoft Surface Pro 5 (2017) and Surface Pro 6 (2018) tablets whose original battery has degraded or failed and who want a direct replacement without modifying the device. It suits students, professionals, and casual users who need a straightforward swap to restore their device to portable use.

It is less appropriate for users who require extended all-day runtimes beyond the rated 45Wh capacity or those who prefer certified OEM parts from the original manufacturer. If maximum factory-verified run time or manufacturer service is required, consider an official service replacement instead.
