AGM Battery Choice

[mtnjag]

I need to replace the battery in my 62 E.
I’ve had an Interstate MT-grp26R at 525cca standard flooded battery in it and would like to go to an AGM battery.
It’s not a mega amp battery and it’s worked quite well so that’s not a requirement.

Not concerned with looks, just fit and weight. Smaller and lighter preferred.
Searched but don’t see anything current on type and size.

Any AGM battery recommendations in the USA?

Thanks.

I’ve had Odyssey PC1200s in both my cars for some years and they perform flawlessly, even in cold, damp British winters. I keep them conditioned with a Ctek mxs5.0. Much smaller footprint and they pack more cold cranking amps punch than the lead acids.

I understand they are manufactured in Missouri USA and Newport, Wales.

I know other owners have had good experiences with other batteries so I think you’ll get a few more useful recommendations.

Optima red top. The die when un-loaded to deep, but when they are treated nicely, they deliver an enormous current.

Had a red top before this Mt26r Interstate. Guess i let it go too far. Died and wouldn’t come back.

Huh, both these batteries are big and heavy, thoght i could find a smaller lighter AGM that would do the job?

Hi Layne...also been looking for a smaller lighter battery (dry) for another XK engined project. .....the AMG,s do look much heavier than standard.......the smallest lightest i could find that seems adequate is a type 075 battery its 14kg its a standard a not AMG....Still looking......Steve

Yeah I agree, not so light. Got a U1R Miata battery for my Sprite and very small but not so light.

A little smaller but close in size to the MT26R is a Xcess power S925, 6.255"L x 6.93w x 4.92h @26lbs.
550CA/no CCA spec (about 20% less per retailer so 440?) so less than the MT 26R but retailer says the AGM will outperform a flooded Lead -Acid. Is that true?
Enough to reliably spin the XK?
I am in central CA so no a cold climate.
