had to replace my battery prior to this last season. would work fine until it was cold out. didn't load test worth a :sheet . i think mine run me about $80.00
If it only reads 12.6v, it's dead. A fully charged 12v battery will read between 13 and 14.4 volts. Anything less, and there isn't enough amperage to start a go cart.
Don't think that's quite right. Average 12 volt battery has 6 cells, each produces about 2.1 volts, for a total of 12.6 volts. Here's a reference chart for open voltages at different temps:
http://jgdarden.com/batteryfaq/carfaq4.htm#ocv_socYou get 13-14+ volts from an alternator when a car is running as that is how the battery is kept charged. So if you take a reading at the battery while the car is running, you'll see 13-14+ volts.
Correct
I am far from expert but the expensive ones maybe AGM batterys (Absorbed Glass Mat) a new tech. made for extream applications. they withstand vibration heat and water better than conventional batteries. (or maybe just a good way to charg more for it) I had to replace the one in my son's atv recently.
