Is it okay to have two different batteries in the truck? My truck (in sig) starts a little more slowly than it should. Did it when we had warm weather too, it's not just a cold weather problem. I feel it's the starter getting weak, and I have a new one I need to install. But, I have a nearly new 850cca battery in the '87 truck in my sig. I would like to take this battery out, put it on one side of my psd, and see if that makes any difference. The batteries in it are 844 cca right now, which I know are a bare minimum.
I would like to swap in the new 850 from my '87, see if it helps, then purchase another 850 just like it in a couple weeks to match it. I can take the two batteries currently in the truck, and put them in each of the other trucks in my sig. I feel certain they would be perfectly fine in either of those trucks.
When I put my new starter in, I'm gonna also check all my connections; make sure they are tight, and make sure they aren't corroded and the wires aren't going bad at the terminal.

The batteries are a set and part of the electrical SYSTEM, including the alternator. Batteries should always be matched for CCA and replaced as a set. If you don't, the weaker battery will drain the other, and place a stress on the alternator. You will be constantly replacing the weaker battery and lowering the life of both at the same time.

Usually not a good idea as OMCUSNR replied but if both batteries are lead acid, same group and close to the same CCA and AH you may be good to go but I always replace them in pairs.
not a good idea. beware of battery sales. there are manufacturing date stamps on batteries. try not to buy anything that has been sitting around for a long time.

Thanks guys. I won't try to run the 850 with the batteries that are in there. The newer 850 was only used in the old truck maybe 5 times max before I parked it due to a hellacious exhaust leak that I haven't fixed yet. I've kept a battery maintainer on it the whole time. If I buy another battery exactly like it, okay to run both of them?

if you buy another 850cca. i would use the good one that you have out of the other truck if it were me.

Yep, I think that's definitely what I'm gonna do. Even if it doesn't crank slowly with the new starter in, just for some peace of mind. The other truck isn't driven all that much, and I think one of the batteries in my psd currently would crank that old truck fine, especially if I keep a battery maintainer hooked to it all the time, which I will. And I can put the other old battery from the psd in my mud truck, which is also rarely used, and is in need of a battery.
