Best Battery for 1983 Aspencade?

the "standby" if there is one, is Yuasua ( sp)
the truth is, get an AGM with more CCA than the OEM specified battery.

I usually order online for bike batteries, for truck batteries that are too heavy to ship, I go to Walmart and get the best I can afford.

Just put a mad max battery from wallmart online in mine. Agm and cheaper than others. Seems ok for now. Did put it on trickel charger till all way up before trying.

Over the years I've had decent service with the OEM YUASA batteries but have been less happy with their AGM. I went with the Mighty Max AGM again because it gave me decent service for a couple of years at a bargain price.
