6 volt AGM battery suggestion request

Post by mehalley » Sat Jul 20, 2019 7:21 am

I'm keen to replace the NAPA battery that came in my 1949 Super 8 with a 6 volt AGM battery. Across the years I've had good luck with 12 volt Optima batteries but I keep hearing stories of how their quality control has fallen off recently. Any advice, suggestions or horror stories from your experience would be greatly appreciated.

I'm still using NAPA conventional lead/acid batteries in my 6 volt vehicle and don't really see much if any incentive to change, I'm easily getting 6-8 years of service with lead/acid and never an issue. I do however follow a lot of forums on collector cars and can't say I've seen anything recently about quality problems with gel batteries.

I think the red top 6v Optima is going to be your only choice in AGM and you will need some kind of clamps or mount as well. I don't believe anything made specifically for an Optima battery will fit on the tray and IMO trying to use the original long hold down is problematic with the short battery. Dorman and Cypress have what appear to be universal looking plastic clamps to fit over the base flanges on the battery that will work although you will probably have to come up with your own screws and drill holes to go thru the tray.

My original battery tray was rusted beyond repair but the mounting legs that bolt to the frame were good. I built a new tray from 1/8 flat steel with angle iron welded to the sides to hold the batteries in place and bolted it on top of the original legs. I used dual Optima 6V batteries but a similar trey could be made to hold one. Built a top to go over the batteries and used standard hold-downs from an auto arts store.
