    Battery Voltage

    I have a HC600 that i've had for about 2 years. I haven't used it in a while and the dmm reads 7.5
    should i take it to autozone to get recharged or just toss it?

    I would at least attempt to recharge and see if it holds, worst case, your back where you started

    You can bring it back. Need a nice charger than runs a de-sulfation cycle / charge. Call Dave the Techie @ Kinetik and talk to him about it, he will recommend a certain $120~ charger that will get this, and all your other batteries in shape.


    /e usually in a 12v 1.x volts per cell = shot which is anywhere from 6.x-7.x so it could be bad but you can break down the crystallization and get some life out of it.

    Good read here

    Re: Battery Voltage

    alright cool. until i can get ahold of one, is it a bad idea to try to charge it off the main battery?

    Using an alternator on a dead/sulfated battery is a bad idea. It is not a battery charger its a maintainer. I would use a ctek 3300 or 7002 or if money is an issue a schumacher xc-6. XC-6's can be bought at wal mart for 30ish bucks but the 70ish dollar 3300 will more than likely do a better job. Only question is what stage the sulfation is in. If it is crystalized it is a lost cause. This is why it is important to keep lead acid batteries charged.

    Re: Battery Voltage

    i got a g31 YT sitting on my back porch. been there 2 years (yellow is faded). checked it 2wks ago... 12.9v



    at 7.5v i would toss it in the recycle pile. for what you'll drop to try and revive it, go buy a new battery w/ warranty.

    Re: Battery Voltage

    I have brought some kinetiks back from as low as 4 volts before. I would get a charger on it to see how far you can get it back. Fully charged should stay at about 12.85 volts then put it on a load tester. Set it to 50 or 60 amps and it should stay above 9 volts for 10 seconds. If it doesnt it may need to be discharged a tad bit then charged back up. With a Ctek you generally do not have to do more than 1 cycle to find out if the cell is good or bad.
