Battery won’t charge

Most "won’t charge" problems are the charger, the socket or the plug, not the battery.

Likely causes

Charger faultyHow to tell: No light at all, or the light never changes. The commonest cause.

Dirty or wet charging portHow to tell: Look in the port: dirt, water, burnt marks.

Battery protection has switched offHow to tell: After being fully drained or stored flat for a long time.

Check this first

Plug the charger into the wall without the scooter. Does its light come on?

Step by step

Tap a step when it’s done to keep your place.

Try another wall socket
Simple, and sometimes the answer.
Look at the charger
Light on with nothing connected? Cable damaged near either end? A charger that is dead or damaged: replace it with one made for this scooter (60 V pack, same plug).
Check the charger output (optional)
Set a multimeter to DC volts (a range above 100 V). With the charger in the wall and not connected to the scooter, touch the probes carefully to the plug’s contacts, never letting them touch each other. A charger for a 60 V pack usually reads well above 60 V (the label on the charger says its output). Some chargers only switch on when they sense a battery, so a zero reading is a hint, not proof: try a friend’s identical charger if you can.
Clean and dry the scooter’s port
Scooter off. Look inside with a torch. Remove dirt with a dry brush; let a damp port dry fully. Do not poke metal into it.
Leave it on charge longer
A fully drained pack can take a while to show anything. Stay nearby and check the charger and deck do not get hot.

Stay safe

Never charge unattended or overnight, and never near things that burn.
Only use the original charger or an exact replacement.
Do not charge below 0 °C or right after a hard ride while the pack is warm.
Anything inside the battery pack, or a pack that is swollen, hot, smells or has been dropped hard. Stop using it and take it to a shop that works on e-scooter batteries.
