My 50cc scooter's battery is dead. I recently bought a transferable car battery charger for when my car's battery is dead. What I want to know is if I can go ahead and use that car battery charger to charge my 12v 7ah battery for my scooter.

Yes you can. A 12v charger can charge any 12v battery. The difference is your scooter battery is 7ah (amp hours, for those reading who may not know) and a car battery is hundreds of amp hours, so it isn't going to take very long to charge the scooter battery compared to a automobile battery. If the charger is an old analog style where you turn a knob to set the number of hours to charge, put it at the lowest setting. If it's a new digital charger, it should know when the battery is charged and will stop charging. Over charging makes the electrolyte liquid in the batteries boil and it just kills the life of them, then they lose their ability to hold a charge. If it's charging and you hear fizzing like soda pop, the electrolyte is boiling, so stop charging.

One more note, is the age of the battery in question. If this scooter battery is 5 or more years old, and it's a lead acid battery, it may just be time for a new one. There are interesting techniques I've seen on youtube of revitalizing old lead acid batteries by dumping the electrolyte, then filling with a epsom salt solution, and getting many more years of life out of them. I have yet to try this myself, but the information is out there.

My best gift to myself ever, the Lightning Pack.

Had to have my scooter hauled into my local Yamaha dealer because I let it sit for over a year (bad scooter mom).

One of the first things he did was whip out this little rectangle thing and start the scooter with it. I was in total amazement as I had never seen one before. He said he starts his hunting buddies truck with it all of the time.

I had to have one immediately. It is part of my emergency kit. Starts cars, scooters, charges cell phones, computers. Has flashlight and beacon. Every kind of charging cord comes with it. I bought mine from my local yamaha dealer but this link is to Home Depot.

On a modern charger most of the time you can even select that you're charging a motorcycle battery and it will tune down the amps a bit. Most modern chargers also have a desulphating option, it takes some time to do it but you can rejuvenate older lead-acid batteries with it and squeeze an extra year or so out of them.

Take a peak over at this thread: https://permies.com/t/84240/Maintaining-Maintenance-Free-Sealed-Lead

Near the bottom, I talk about the SKYRC iMAX B6 Mini charger. I can't say enough good about this little guy. It charges ANYTHING- for $16 US.

And you can charge one battery from another battery. I use it with a 18Ah 12 Volt battery to charge my drone lithium batteries in the field.
