Battery Charging probably been asked before

When you charge the batteries in these trucks and you hook up your charger to say the drivers side does it also charge the passenger side battery at the same time? My assumption is yes

I bought new batteries awhile ago but when my truck sits for a few weeks the batteries do draw down . Although my truck will start I know they aren't up to full potential so I like to charge them up as you aren't doing your electrical system any favors by not doing so. Basically I start it up move it only let it run for about 15 mins as it's inside then shut it down then repeat to put it back in it's out of the way spot. So IMO this labors the alternator the batteries and starter and wiring doing this so I charge my batteries.

Friday I put the charger on the DS and there was a significant amp draw. When I came in the AM it did not show a complete charge so nonetheless I hooked up the PS and there was a min amp draw in with in a matter of a few minutes the battery was fully charged.

With the old batteries when I did the exact same procedure it seemed the PS battery took longer to fully charge but not as long as the DS and I assumed that battery DS was junk. The batteries were old enough to be changed out anyway.

So do they charge together or do I have a bum battery? Also do I only need to hook up to one battery to charge both if they charge together? I am assuming they charge together,at least I hope so.

This is how I charged mine as well as others when they needed it. Mine always seemed to charge both but I also did not put a multimeter on the opposite battery to check. I would unhook the batteries if your getting a draw while there just sitting there (does sound like quite a bit of power loss through them though). I also would only start it when you need it. The extra acids that sit in the exhaust will help corrode the inside of the pipe premature. Also if it's very cold out the starting and stopping can create condensation in the motor and without getting it to operating temps the oil cant burn off the water that accumulates in the oil like it normally does. I'd take it out for a good run. Just thoughts and weird crud I've seen over the years Mackin.

Ya it'll charge both since they're wired in together. I charge mine the same way and it always charges them both all the way. I could be wrong but I think the power from the alternator only goes to one battery as well.

Disconnecting the batteries would be the best option but a pain to do. Charging is easier IMO. It sits inside a heated shop but blocks off equipment I need to run occasionally,thats when I need to move it.

I know it's not good to do what I'm doing if this schmuck that rents two garages off me who owes me a shit load of money would get out then this problem would be solved!

I only take it out this time of year occasionally for a good blast. So in the mean time until this douche bag gets out it appears I was correct on my charging theory wasn't 100% sure they charged together.

Thanks for da info

Yea, it's a pain. I would just take the positive terminal off each. Or you can get one of those battery disconnects for a boat (only thing I've seen them on). It's a big rotating dial with stop positions at, off-1-2-both that you just turn the dial to if you want it disconnected, battery #1, battery #2, or both batteries. There pretty slick. Should probably take a pic of it. Or just one big battery disconnect at the junction block (cheaper and quick).

I've always used the junction box?
