Why does the battery not last as long as advertised?
If you are using the vehicle on a surface such as grass or wet tarmac (we don’t recommend this) then it is only normal that the battery does not last as long. Going uphill or exceeding the maximum user weight also has a big impact on battery longevity.
In the cases where the car/bike feels more sluggish than usual, then the battery is most likely undercharged. A full charge should bring things back to normal, however, if you feel the battery is beyond saving, we do stock a full range of batteries so please contact our customer support team for help! :).
