The car battery was a good idea, eh?  |

Looking for batteries online right now. Dimensions are:
Product Width 3.54"
Product Length 5.12"
Product Height 4.49"
Are the ones that must be filled by the customer any good?

My questionable scooter battery is an 8-amp Bike Master TruGel MG7C-A non-spillable. There is this number stamped on it: M0107DA6. Is that a date stamp?

I figure buying a new battery is never a bad idea anyway since they only last a few years, and the one I have is probably pretty old. JR, make sure you reread my prior post which I edited to say that my scooter battery has only 11.1 volts now.

Already done. Hooked up car battery without scooter battery in scooter. Scooter lights work great. Scooter started easily. Turned off scooter engine. Started scooter again easily. Repeated 5 times. Scooter started easily 5 times, so it must be either bad scooter battery or bad battery terminal connection, right?
Now I inserted the questionable scooter battery back into scooter. There was no snapping sound that usually happens when connecting a battery. Scooter lights did come on and scooter did not start. I then used multimeter to see that scooter battery only has 11.1 volts now, so 12.7 must had been just a surface charge as Alleyoop suggested. Time for new battery, right?

I removed the battery in order to take it to get tested, so I will eventually reconnect it carefully. It did have some kind of brown grease on the terminals. Does that matter?
With the scooter battery removed, I will connect a jumper cable from the positive terminal of the battery inside my car to the positive terminal connector in the scooter. I will then connect the other jumper cable from the negative terminal of the battery inside my car to a non-fuel piece of metal inside the scooter. I will then try to start the scooter with the car engine off.
Actually, I could connect the negative cable to the negative terminal connector in the scooter since there is no battery inside the scooter which could explode.

Question 1: If I give up trying to fix it, any idea how much a shop would charge to fix my scooter?
Question 2: Can I try connecting a car battery to my scooter to see if it will run? Or would that fry my scooter?

Just had battery tested and Walmart and Sears. Both told me the battery is bad. Walmart gave me a printout that stated voltage 12.77 volts, and CCA 89. Not sure if battery is really bad because maybe the testing maching assumed it was a large car battery.

Charged for 4 hours. Unhooked chargers. Battery reads 12.78 volts using multimeter. Turned key. Lights do not come on. Engine will not start. Hooked up charger again. Lights still will not come on. Could the battery need to be replaced even though it reads 12.78 volts?

Just hooked up charger. Turned key while charging and lights turn on!
If the battery turns out to be bad, can I buy a 6 amp battery even though the scooter's manual states 7 amps?

And I can test magneto by seeing if voltage increases when engine is running, right?

Ok I will charge it right now with my Schumacher SE1052 battery charger set at 2 amp slow charge.

Manual states A.C. Magneto charging system. I did not charge the battery, but it had enough juice to start the engine, so it should have enough juice to turn on headlight with key turned, right?

Turned key this morning. Lights came on. Scooter started. Turned it off. Would not start again. Lights will not come on again. Opened panels. With key turned, I wiggled all electrical wires but lights did not come on.
