Location: Mauston, Wisconsin | LOL- $325 for an 12V AGM, thats insane unless they weigh about 150-200lbs each. Check your charger voltages, If its higher than 13.8V w/ digital voltmeter, the charger is not set up for AGM's or its wrong charger for them - get regular wet-cells and check the electrolyte levels periodically - refill w/ distilled water ONLY!
I buy my AGM's and wet-cell batteries from Walmart, because there's usually a Walmart around, even in Canada.
AGM's do have an advantage for a starting battery, they can deliver more instantaneous current/cold-cranking amps versus a wet-cell... thats why I have a dual purpose AGM for my starting battery and electronics. That's also why your vehicle typically comes with an AGM starting battery....
Most marine battery chargers are float chargers/automatic trickle chargers. Its a matter of symantics...trickle charger versus float chargers -> Do not trickle charge during storage, you are asking for trouble and will be aging the battery...its complicated. A real trickle charger only, cannot recharge a standard lead-acid battery properly.
But OK, go ahead its your money. Believe all the urban legends you want, both Shep & I know of what we speak....if you can hear sizzling you have destroyed the battery!
Have fun!
