Well, it finally happened to me. I've read about the L-series and how when the battery gets weak, you turn the key and don't even get a click. Thought it would never happen to me but it did and at the worst possible time too.
I was in Vermont last week and found that you could drive nearly all the way to the summit of Mt. Okemo. The wife and I along with our two cocker spaniels made the trip and parked near the top where the paved road changes to a rocky dirt road. It's about another 1/4 mile to the summit by the trail and I hiked it with the dogs. Wife stayed in the car. I should also note that the wife has some medical problems and though I didn't think that 3200 feet height would be a problem, it was. In the 20 minutes it took me to kike to the summit and back, wife had been running the blower - on high - with the engine off! Needless to say, the battery was dead and the wife nearly so with purple lips. I was about to roll the car down the hill using the foot and hand brakes which would have been very scary (no guard rails and several hundred feet drop on one side of road). Thankfully another car approached and gave us a jump. As we got down toward the base lodge, wife began to pink up again and all was well. Whew! Now seriously considering the purchase of one of those emergency battery packs. Also going to cary a cylinder of oxygen.
The battery probably was the original in the 2001 LW300 and didn't want to take any chances even though it otherwise seemed fine. Drove into Rutland and got a Sears Die Hard (no pun).
