Description
The Autel Replacement Battery for MD909 Pro is a genuine internal battery pack designed specifically for the Autel MaxiDiag MD909 Pro handheld diagnostic scanner.
This battery serves as a perfect replacement when the original internal battery has aged, lost capacity, or no longer holds a sufficient charge — restoring reliable operation and extending the life of your scanner. MD909 Pro devices are powered by a built-in lithium-ion polymer battery (nominally rated at 3.8 V/5000 mAh), which delivers long runtime for full system diagnostics, live data viewing, and service functions.
Replacing this battery helps maintain consistent power delivery during extended diagnostic sessions, preventing unexpected shutdowns and ensuring your tool remains ready for workshop-level use. Ideal for technicians and DIY enthusiasts alike, this replacement pack is a practical maintenance accessory when the internal cells degrade over time.
