Tying this thread to my genset starting issue, I am looking for assistance as I try to figure out my battery bank.
It appears that I have 2 Lifeline GPL-4D as chassis batteries. These are AGM, deep cycle but have 1100 CCA. I also have 2 of these same batteries as part of my house battery bank. There are 4 Lifeline GPL-4CT 6v as well. I believe the GPL-4D are correct and think the 4CT are correct from the dimensions and from the electrical schematic book.
If I change the house batteries (so I can start the genset and have reliable house power) should I stay with these size of batteries. I have physical room to but bigger batteries (not taller) where the 4 small batteries are located. I see from the Lifeline page, these 6V batteries are better than the GPL-4D in discharge rate.
I don't have a Lifeline distributor near me (closest is 2.5 hrs and I'd have to cross into North Dakota and then pay possible duties/fees when import back).
It is somewhat confusing to me that I have 6 and 12 volt batteries in the same bank, although I understand how it is done. Lifeline does suggest equalizing them if they do not hold charge well but given they are 6+ years old I don't know if that makes much sense to try.
I know from past experience the battery store in Winnipeg is a Trojan fan and will likely try to convince me to use Trojan. Good batteries, although I am now partial to the 0 maintenance aspect of the AGM, albeit more considerably more expensive (last year the Trojans were $165 and equivalent AGM was $335 - I know we are gouged in Canada but that seems quite a difference in price.) I will contact the Lifeline dealer in Grand Forks ND and see what their price is for replacements - may make the drive worth it.
I guess I'm not sure what I am asking, just looking for thoughts and suggestions re. batteries.
