Battery question for begineer (sort of)

My opinion.

the Cabelas AGM battery may not equal a Concorde lifeline but I can just about guarantee that the Cabella AGM battery is a whole magnitude of higher quality than a Walmart battery. 22 and a half amperes charge rate per battery is borderline low for an AGM battery. but if the battery is not over discharge to less than 50 percent remaining capacity 22 and a half amps should not pose a problem. a serious problem exists if insufficient amperage charge rate is coupled with a less than full recharge repeatedly. Overly slow recharging coupled with less than fully recharging the batteries can damage your AGM battery.

I recommend downloading the Concorde lifeline battery manual online it's a PDF file and then studying the manual thoroughly because the manual covers all aspects of operation and recommended charge rates for AGM batteries. You can call this sort of a Bible for AGM batteries. I have not found another user reference source for AGM batteries as comprehensive as the Concord lifeline user manual. It covers charging parameters in exquisite detail.

Car jar flooded batteries are pathetically manufactured and promoted. there is no way on the face of the earth that a group 27 truly cyclable battery is going to render 700 cold cranking amps we're talking about flooded batteries now not AGM. Declaring a group: 27 flooded deep cycle battery to have 700 cold cranking amps would be very similar to declaring a John Deere tractor tire to have a speed rating of a hundred forty miles per hour. It's an insult to a person's intelligence.

The Group 29 30 and 31 batteries are an inch longer 13 inches versus 12 than a group 27 battery. the difference in capacity of the 29 30 or 31 is not earth shattering from the capacity of a group 27 battery.

Whatever you choose I hope it works out for you.

The Lifeline documentation and specifications are fine for Lifeline AGM batteries, however, AGM batteries of different manufacture often have different capabilities and charging requirements. So, while the Lifeline manual is informative with some general information about AGM batteries, it might be prudent to obtain the documentation for the batteries one chooses, if they are not Lifelines.

Fullriver also has pretty comprehensive documentation for their batteries, but I wouldn't recommend it, or the Lifeline documentation, as information that covers all AGM batteries of varying manufacture.
