Use this guide to replace an aging or faulty battery cell. MNT Reform uses eight 18650 3.2V LiFePO4 batteries in series, which can be replaced individually.

When fully charged, the battery cells combine to a voltage of almost 29 volts, and can easily deliver multiple amperes of current. Do not touch the metal pins of the battery holders with metal tools.

When replacing the batteries, pay attention to the polarity! Inserting a cell the wrong way in will damage your device.
The circuit board indicates the + and - orientation for each cell.
