Which batteries for a for a 24v system? Red Top Optima?
Yesterday when I left work, my batteries barely had the juice to start my truck at 7-8' celsius outside. I thought I had left my lights on or something (which I don't think I did). Ran around all last night and they charged up. Started and stopped just fine, but the truck was warm.
This morning at 0' there were dead.
I could barley turn the truck over.
Almost started, but it never quite caught.
They read about 22-22.5 volts before glow plugs cycled on.
Then after the plugs cycled they barley had 20.
Started dropping fast from there.
I think I am currently sitting around 18v after it sits for 5 min.
I also use my truck a few times a day.
So its not like there where sitting and draining from no use.
I also know my alternator is good, because I show full voltage when running.
Anyways, I need new batteries. The batteries in the truck may or may not be under warranty, but the closest Interstate Batteries dealer is 4 hours away (Calgary).
I am thinking another pair of Optima's.
I measured my space. I got 12" deep, 7" wide and about 7.5" tall.
I am thinking the biggest two red tops I can get.
I know its important to get identical batteries.
I live in Cranbrook BC, so it does get somewhat cold here (down to about -35') with an average being -15 to -20. I also do have an electric winch, but I always run the engine while winching (when I can anyways ), and with 2 batteries I should have more than enough juice for a self recovery without engine power.
Any advise would be appreciated.
Thanks
Nick
