Battery Voltage?
« on: June 15, 2011, 12:59:22 AM »
Thanks everyone for your help thus far it is greatly appreciated!

Here goes again. I'm about to test my scooter's battery since it's been almost two years since it started. I  wanted to know if anyone could tell me the voltage I'm testing for?

should be between 11 and 14.4 as with any 12 volt battery  :)

If you really just left your battery sitting for two years it will be dead for sure by now, no need to check  :(

And by the way, checking a battery with only a voltmeter without applying some load, and without knowledge about the way the specific type of battery is supposed to behave under different conditions, is an exercise in futility.

Harsh reality, sorry...

If you have a charger its worth charging it up and trying it anyway. I was given a scooter from a friend that had sat for nearly 3yrs, after I got the scooter fixed I charged up the battery and it worked 1st time. Ran about for a few months then sold it to a neighbour. Its still using the same battery yet.

I took it to the car dealership I work at and they tested it for me and I found out it is definitely no good. Hooked it up to the tester and it read only 3v...

Luckily found one right down the street for about $40 which doesn't sting too bad.

Good tip blue, will keep that in mind myself, I got 3-4 old batteries on a shelf in my garage.

Reanimated old batteries (reanimated old bats ? :-) (lead-acid type) will only work for a few times and become worse every time you discharge them, that's my experience at least from owning and driving quite a lot of old cars, mopeds and a scoot, and it appears to be confirmed by technical publications I've read.

But if you've got some batteries that are not completely dead and reanimating them helps you through summer with no extra costs, the extra work can be worth it, especially in case of cashflow deficiencies haha...

Be prepared for winter though, battery condition really shows at low temps.
