When an electric scooter or e-bike won't turn on or won't charge, the battery is the part riders fear, but it's often something smaller: the charger, the charging port, a connector or the power button. Our technicians test in order, from the cheapest part to the most expensive, so you don't pay for a new battery you don't need. Looking it over and telling you what we find is always free, and a "won't turn on" repair starts from $35, parts and labor included, on any brand.
If the battery is swollen, has been in water, smells or gets unusually hot, stop using it and don't charge it. Bring it straight in. Our swollen or wet battery safety check starts from $70.

Every price is a starting price that includes parts and labor; the final price depends on the model and the part. Electric scooter battery pack and BMS replacement are done at our shops in cities where electric scooters are legal to ride, so call (516) 300-0944 first and we'll tell you which shop to go to.
What our technicians check when it won't turn on
A ride that's completely dead, or that powers up and cuts out, gets checked in this order:
- The battery's charge and voltage. We measure the pack directly. A pack that reads well below its rated voltage points to the battery or its BMS; a healthy reading means the fault is further along.
- The power button, key switch or ignition. Switches wear out and fail, especially after rain.
- Fuses, connectors and the wiring harness. A loose or corroded connector between the battery and the controller is one of the most common faults we find, and one of the cheapest to fix.
- The display. On many models the display is part of the power circuit, so a failed display can leave the whole electric scooter dead.
- The controller. If power reaches the controller but nothing happens, we test it, and we read any error code on the display. If your Segway or Ninebot shows a number on the dashboard, see Segway Ninebot error codes. If it powers on but the motor won't drive, see electric scooter motor repair.
- The BMS. The battery management system can shut the pack off to protect it. We test whether it's done that for a reason, or failed.
What our technicians check when it won't charge
- The charger. We test its output. A charger whose light comes on can still deliver too little, and a replacement starts from $35.
- The charging port. Bent pins, corrosion and loose wiring behind the port are common, especially after wet rides; port repair starts from $35.
- The battery under load. If the charger and port are fine, we run a load, capacity and discharge test (from $50, waived if your repair quote is over $100) to see how much of the pack's capacity is left.
- The BMS. A pack that won't accept charge at all is often a BMS fault rather than dead cells.
We give you the results and a price before any repair, and you decide. If the battery does need replacing, see electric scooter battery replacement or e-bike battery replacement in NYC.
Batteries and the law in New York City
Since September 16, 2023, NYC's Local Law 39 has banned the sale of e-bike batteries that aren't certified to UL 2271, and Local Law 42 bans batteries rebuilt from cells taken out of other batteries. So when a pack does need replacing, it has to be a certified one, not a cheap rebuild. Our NYC battery law guide covers the details.

Frequently asked questions
Why won't my electric scooter turn on?
The most common causes we find are a flat or protected battery, a worn power button or key switch, a loose or corroded connector, and a failed display or controller. We find out which with a free simple inspection, and a "won't turn on" repair starts from $35.
Why won't my electric scooter charge?
Usually the charger, the charging port or the battery's BMS rather than the cells themselves. A charger or port repair starts from $35; a battery test from $50, waived if your repair quote is over $100.
Do I need a new battery?
Not always. We test the charger, the port and the BMS before we quote a battery, because those are much cheaper to fix. A battery pack replacement starts from $500.
Is it safe to keep charging a battery that's swollen or got wet?
No. Stop using it, don't charge it and bring it straight in. Our swollen or wet battery safety check starts from $70.
Do you fix brands you didn't sell?
Yes. Any brand, any issue, wherever you bought it.
