Default Opinions on AGM Batteries

OK Folks, My Roadtrek coach batteries are getting a little tired and I am looking toward replacement. I am thinking of going to AGM instead of flooded because I am tired of deteriorating battery tray, slides and terminals from acid fumes.

At a local battery store today I spoke with the owner and asked about Lifeline as a possibility. He had the line and agreed that they were certainly top end but also suggested I consider Energy Power Vision EVGC-220A-AM which he related were big sellers for his solar power installers.

Lifeline GPL 4CT: $349.95
Energy Power Vision EVGC-220A-AM: $246.80

Has anyone had experience with these batteries?

Thanks

No experience with them, but here is the spec sheet from the manufacturer.

https://visionbatteryusa.com/wp-cont...GC-220A-AM.pdf

The thing that stands out if the number of cycles at 80% discharge being speced at 800 cycles. This is way higher than anyone else that I have seen, and I think Lifeline is at 550 cycles for reference. They show 1200 cycles at 50% compared to 1100 for Lifeline and others.

It is very hard to know without anyone having actually used and abused them, as specs are always suspect. Most likely these are out of one of the big Chinese factories that do lots of private label stuff and also often sell under their own brand too, which these may be.

We got our Lifelines GPL-4CT for $299 each.

Costco is currently using Interstate for their batteries and might provide you
a good bang for the buck.

Default AGMs

Thanks Booster, Idid see the spec sheet and, frankly, donít know whether to be impressed or skeptical of the 800/80% figure. The battery dealer told me that the battery was made in Korea.

Where did you source your Lifelines?

We got ours from Powerstride, at $299 free shipping no tax, but I now see the are at $328 for that method.

Interesting that a Chinese company who touted all their China certifications on their website, would have a battery made in Korea, but who knows?

The store owner could well have been wrong.

Everyone I know has ruined a set of AGM batteries. I stick with flooded lead acid batteries. I have noticed when they approach end of life they cause corrosion (don't know why.) I replace them at that time.

depending on the age of your van you MAY have to get a new charger.

Under what circumstances have you seen AGMs fail. At what age? What type of charging system was being used?

Thank you for any information
John
