Battery not charging (to full capacity)

Troubleshooting Steps:

  • Inspect the charger for any cable damage, check if the charger indicator light is working properly.
  • Inspect the charger tip for damage. Look out for any bends, breakage, damage to the metal sheath.
  • Perform a voltage test on the charger
    • If charger voltage output is lower than 54V or the voltage is not stable, please make a short video and send to MATE
    • If the charger voltage reading is OK, continue troubleshooting the charger.
  • Inspect the fuse for any sign of damage.
    • Remove the fuse from the battery head.
    • If there is a visible gap in the wire or a dark or metallic smear inside the glass, then the fuse is blown.
  • Charge the battery for at least 4 hours and perform a voltage test on the battery to make sure it is within range of 54.6V when full; at least 41.6V when discharged.
    • If it is below that range and the charger is OK, then the battery will need to be “jump-started” by leaving it on the charger for 5-8 hours regardless of the light being green on the charger.
  • If using a “Rapid or Speed charger” the cells will only get roughly an 85%+/- charge, also batteries degrade over time, so it’s normal and expected for the battery to lose initial capacity over time.
