Hi, I live in a cold weather region where temps drop to -40 deg F or
colder during the worst part of the winter, and I don't have a garage. I
need to replace the battery in my wife's Suburban which is driven around
three times a week. Battery store is recommending a quite pricey AGM
battery with high CCA, and also to install a trickle charger. But part
of me is still wondering about the cost-benefit part of it and if maybe
I should just get one of the less expensive non-AGM batteries with lower
CCA. I think I'll install the trickle charger in any case, as I already
have a spare one I bought a while back.
