Had two yellow top Optimas in my Jeep with a nice isolator setup (which dad bought off me and was using as a dingy for his RV and has a daily driver). Primary battery lasted 2 years then died. Took it back to 4WP and the warranty was basically useless, prorated down to the value of a chicken sandwich. OK, things happen.
Put a new Optima red top in the truck last April. This morning the wife reports the truck battery is dead. It's been sitting for a few weeks and without any real sun on the solar panel to charge it I thought... yea, not too surprising. Put the battery on the charger, and FOOF, the charger goes up in smoke. WTF? Put the meter on the battery, 5.2V. Wow.
Went to costco and got just a regular old battery for the truck. Done with Optimas, that's 2 failures out of 3 on 2 year old or less batteries with zero hard use. No winching, no crazy desert racing, just starting.
Now I have to go buy a new battery charger too, can't get that magic smoke to go back in.
I had great luck with them in the past in Jeeps, 4runners, etc but these last batches have turned me off for good.
