AGM vs lead acid battery

[ROZ]

I did a quick forum search and didn't find any reviews.

Is there a reason not to use them? Drop in performance or use time?

Thanks!

I think the cost has been the deciding factor against them.

i,ll 2nd that i think its been cost prohibitive ..........................

Well I ain't no guinea pig.. new trojans it is...

The sparky drag race guys use them because of their light weight, smaller footprint, high-amp discharge capability, and fast recharge. They also get sponsors to pay for them.

They recharge quickly? Does that mean they discharge faster than a lead acid?

My Dad has a bunch of AGMs' that he scored from a guy.We looked them up, about $325 each!!He put 3 in a Caroche he bought.It ran a suprisingly long time on a charge.I don't know exact use time,but he said that he could run it around for days at the house with out charging.The ones he has are the size of a Group-31 Heavy-Truck battery.I put one in my kids power-wheels,charge it for 3-4 hrs,they ride it for about the same amount of time(And boy does it move and do wheelies!).

325 ea???

Makes a set of Trojans seem CHEAP.

My thoughts on AGMs....

Not only are we a Club Car dealer here in Augusta but we are a Stealth dealer as well. The only experience I have with AGM batteries is through Stealth. Stealth claims that if you discharge a pack of AGM batteries below 50% 3 or 4 times it will severely impact the discharge time of the pack. They claim they have longer range than a set of lead acid batteries, but what good is that if you can't use it to below 50%? Sounds kind of like a new car salesman saying that their new vehicle will go 600 miles on a tank of gas, but dont put more than 200 on it before filling it back up or it'll damage the engine... Lead acid batteries get my vote. Also... the On-board computer on a Club Car would probably freak out if you hooked it up to a set of AGM batteries. You'd want to bypass the OBC and use a standalone charger with a timer in it calibrated for the AGMs.... No thanks.

Not necessarily. The discharge rate is determined by how you use them. The amp hour ratings are your best tool for comparisons, especially when range is the parameter.
