There's no electric scooter sections... Hmm... Oh well here's my question:
Just got an electric scooter for free. Batteries are dead. Can I charge them with a regular scooter battery charger? I tried to hook mine up to them but the lights just blinked which only happens when I cross the charging cables by accident. So I'm thinking either these batteries are completely shot or my charger doesn't charge them? They are 12v 7a batteries, just like my regular scooter batteries but instead of screw in terminals they have spade terminals.

So I'm thinking either these batteries are completely shot or my charger doesn't charge them? They are 12v 7a batteries, just like my regular scooter batteries but instead of screw in terminals they have spade terminals. I wouldn't know but it's an interesting question because I think Lithiums are 3.7v per cell, but acid batteries are around 2.something volts, and then there's the question of whether they are hooked up in parallel or series, and what the charging system was set up for, i.e. for 36v. If you separate them, assuming they are in groups that make two terminals higher than 12v, then maybe you could charge them one at a time, but lithiums are going to want a different voltage, plus they have a rating for how fast they can be charged. I'm looking forward to seeing the answer as I have never worked on an electric scooter. I see now that you said yours are 12v, so if you separate them, or otherwise make sure they only need 12v when wired together, then you can probably charge them with your charger. |

I charge my 12v/10ah lead acid batteries for my electric bike on a small charger that came with the kit. I have never tried to charge them with my car battery charger. I suspect the amperage is far lower on the charger that came with my ebike kit.
-There is a section on endless-sphere.com for electric motorcycles and sit-down scoots. However, here are very few motor scooter styled electric scooters posted on that site. The stand-up electric scooters are very popular on that site.

I second endless-sphere.com A really helpful and fun site. I got a small 300W scooter on craigslist that had two 12v batteries wired together, and I just took off the jumper wire connecting them and charged them both separately with my battery tender jr. and it worked fine until I got an actual charger made for the scoot.

That is what I tried to do. I seperated them and tried to connect each of them one at a time to the charger but the charger which is one of those automatic chargers with 1.5a it just blinked the red and yellow, normally it is supposed to be steady yellow to charge and green when full. |
