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.

If the battery is brand new, follow these steps: 

  1. Charge the battery for up to 4 hours past when the charger turns green 

  1. Check voltage of charger to make sure it is putting out the correct amount to charge the battery 

  1. Inspect the fuse on the battery, if it is damaged, then replace it 

  1. Consult charging section recommendations on this assistance page 

  1. If out of warranty consult an eBike/battery shop for diagnostic or replace the battery through a MATE authorised dealer
