If the battery is too far gone, hook it up in parallel with a good one and then hook up the charger. Some chargers need to "see" some voltage before they will begin charging.


Yep, I had a dead truck battery this week, and hooked up my "smart" charger to it since it was closer than the dumb one.

Unfortunately the Bat was only showing 4V, so the charger thought it was only a 6V battery. It obediently went to work & charged it all the way up to 6V, and showed full! Still didn't start the truck though.

After that, I got the dumb charger & let them work in parallel for a while. [emoticon]

OP here

So, I was going to need wing nuts for one of the batteries. Turns out it is stone dead. So, I will see if a local auto service shop can charge it as mine can't. If not,t he need for wing nuts is the least of my worries.
Your battery is compromised even if it apparently charges up. Have the battery LOAD TESTED.

But regardless it's highly advisable to replace both batteries.

Wing Nuts, helping sidecutter or linesman pliers deficient thieves steal batteries since 1852.

It is one of my older ones that I had planned on replacing. Looks like I'll be replacing it slightly sooner than planned.

I planned that once it was charged to have them load test it too. I will try the parallel charge first. If it works, then I will bring them to be load tested. I have one battery that I know is a year old. The others are older than that, but not sure of.

It will take them a few minutes just to get to the battery on my good TT. It is not just out in the open on the tongue. There is a cover that has a wing nut holding it down over the battery box and propane tanks. It makes noise to remove the cover. Then 2 wing nuts for the battery, and 1 wing nut holding down the propane. Not a quick, easy or quiet process.

I vote for using wing nuts - better that they steal the battery than the RV.
