I've had two red-tops go dead on me. The first time was after about 10 months of use, and that was with no winching and very little load, i.e. not running the stereo with the vehicle off, leaving the headlights on, etc. I just replaced that one in December of last year and it "died" on me again a couple of weeks ago. Extremely slow crank at start, won't hold a charge for more than about 3-4 hours, etc. I trickle-charged it overnight, cranked like a mofo the next morning. Cranked a little slower that afternoon, was back to slow crank by the following morning.
I'm dealing with 4 Wheel parts Whoresalers as we speak trying to get it warrantied. Optima's policy is to trickle-charge it overnight at the place of purchase to determine if it's bad. Lonnie at the Lynnwood 4WP tells me on the phone today that it charged up fine. I had the Jeep over at Lynnwood Auto Electric the day before, they ran a static current draw test, said the Jeep was not drawing as it sat with the engine off. Ran a voltage and amperage test with it running, the alternator was charging fine. Ran a load test, the regulator was adjusting to the load change fine. The owner Larry tells me that the only other alternative is a bad battery, one that won't hold a charge.
Lonnie at 4WP is going to get back to me after the optima rep returns his voicemail. I'm afraid I'm in for a fight here. I'll get the Optima reps number and talk to him direct if need be. maybe they won't warranty their shitty battery, but he'll know exactly how displeased I am, and how I will trash-talk their crappy batteries every chance I get if it turns out I only got 6 months of service out of my fancy-pants $130 Optima.
