SOURCE: On an E 100 Razor scooter, the battery charger shows charged

We had the same problem that I found to have a very simple fix. It seems all that needed to be done was hold in the reset button a few seconds while the battery charger was plugged in and the light on the charger turned to red and the battery charged again. Seems like too easy of a fix but it worked for my kids scooter.

The batteries are dead. The battery in these scooter need to be kept charged or if not in use for a long time charged every 3months. Otherwise, like what to you, they will go dead. The chemicals in the battery have deteriorated to the point where it won't hold a charge. Replacement batteies are available at:

I have this same problem? What do you do? I bought a new charger thinking it was that and the light stays green on it too.

It is possible the new controller is defective, however just because the voltage is showing 24v it may not be outputting the correct amount of amps so don not rule out batteries before checking the following:
To test a battery you need to 'load test' so (with help) connect the battery directly to the motor when weight is on the scooter to see if it will still pull.
Please also remember that you do have to push the e100 to 3mph before starting (many users do not know or forget this step)
