Is anyone familiar with the AGM batteries ? I see Costco is promoting them and they are really expensive but are they worth it ? I am thinking about a 6 volt. Fiberglass and lead plate technology, is it rerally any better ?
When I can afford an AGM battery, I will get one from Saskbattery but right now I can only afford a regular battery so I got one from NAPA. Someday I'll get an AGM.
Why would you want an AGM?
They are designed for the new garbage cars that turn off the motor when stopped at a red light.
Will you be stopping your engine so frequently?
I use AGM batteries in the Bantam and Dog Spit where they are inside the car and need to be spill proof. I also use them in the garden tractors. I use lead acid in the Studebaker and the roadster pickup.

the downside to AGM is that if you kill it or leave it at almost depleted - they do not charge back up properly - if at all. They do not like deep cycling at all.
Where as a lead acid battery will most often come back fully
I find if an AGM is depleted or there abouts, if you put a lead acid battery in parallel between the charger and the AGM, it usually recovers quite well. I do this even with an AGM specific charger.

i have been using them for some years now and i have found if they get low they react a lot better with a trickle charge. my h-d wrench put them onto me maybe 10 yrs ago as i was only getting 2-3 yrs on lead due to the vibration. he caught it with the newer bikes having theft alarms and going through lead batteries with the vibration. since i switched to them on my small stuff i charge them full in the fall before i disconnect and trickle charge in the spring. probably getting 2 times more life time. just saying.
