    I have a International roll back truck I haul my daughters pulling truck on.. I havent used it this winter, I got in it yesterday and the batteries were dead as a hammer.. It has 2 big batteries in it, wired together, when I put my charger on one of them..will it also charge the other one? thanks!

    Depends ! If they arent ruined by leaving them discharged all winter---AND--you are using them wired parallel (12 Volt starter) they should be able to be charged up and good to go. If the batteries are wired in series, (24 volt starter) you will have to charge them separately unless you have a 24 volt charger.

    Charge one at a time, if you don't the weakest cell will regulate the the charge of the other good cells.Watch your water levels, make sure you don't boil them out at to high of a charge rate.

    Patience, is a virtue in battery maintenance

    Lived with batteries for years on an old diesel sub.

    check and make sure that the batteries did not freeze and warp the plates. Hard to tell from the outside. I would use a fast charger about 40 to 50 amps for about an hour and then reduce the charge rate. Bring the batteries inside for a time and let them thaw out before charging. Make sure they are fully thawed all the way to the center. Also try a hydrometer to see if you get any reading of the state of charge in the electrolyte. Might also put a volt meter on the battery while charging. Once you have some type of a charge in them check for a drain on the battery. You can use a volt meter or milliamp meter motordoc

    Disconnect the bateries from each other ane the engine. Loosen the cell caps if you cna and charge each battery alone.

    Protect your face. Charging batteries can be dangerous and they can explode if the charging area isn't well ventilated. Before you start charging the batteries, clean the tops off very well.

    I'm an old Western Auto man. Charged thousands of them. Be careful.
