I know where I'm getting my next battery.
So, HJ-45.
Looks like the standard Group 34 battery costs $189.99.
In a nutshell the problems with the Optimas are fairly common in the car audio forums due basically to operation outside of their "sweet spot" or where they like to be in terms of DOD and recharging. I would be very curious to see what a 1-2min 6000lb pull on a pair of redtops or yellowtops leaves their voltage at when finished. And what their Cranking amps(not cold cranking amps) at 1min or 2min are. This might start to hone in on what the ideal operating sweet spot the optimas perform in.
Best Battery= The Panasonic battery that came with the 80 from the factory.
Unfortunately you can't get them in this country, the average lifetime of that battery is 7 years.
i am done with optima... went wheeling this weekend in the 4runner broke for lunch for 20 minutes and left the cb on by mistake and it drained the red top, had to be jump started by a jeepi have owned the battery for 2 years and its starting to let me down the cb draining after 20 minutes was the breaking point for me
Best battery = Odyssey.
