AGM batteries. Any info?
Long story short, I need a battery for my PA.
I was wondering whether anyone has had experience with asorbed glass mat cell batteries? I was looking at the Canadian tire eliminator spiral grid battery. 770cca. Its noted for excellent cold starting, superior power, and durability. Whereas lead acid batteries typically last 4-6 years (avg i've seen, 5), these batteries last longer? I would theink with a 10 year warranty compared with a conventional 3/2/2 year warranty for a reg battery, it seems these batteries ought to last at least that long.
Second, the battery i have has arounds 400 to 500 cca. I think these cars need a min of 600? Also, i know the agm batteries need a special charge, so how would that play out with the regular alternator?
I am a mechanic and ought to know the answers, but i just wanted to do a little research before i spend the premium for a top grade battery..
I'm thinking of buying a second for the boat too..
