Need a battery. I have used optimas in the past. A few were great and a few were junk. Might have been a bad batch or? Noticed they were bought out in 2000 so maybe things have changed since I got my junk ones. Anyways, the Exide seems to be about the same thing, although it doesnt say TOTALLY sealed, and it says you can mount them in ALMOST any position, whereas the Optima says SEALED and in ANY position. Neither one of those are too big of a deal to me though. The Exides are a little cheaper too. The Exide also offers a much better warranty- Optima is 12month free replacement, 12 month pro-rated Exide is 18month free replacment, 36 month pro-rated Anyone run the Exide batteries or have experience with them? Or should I just go with another Optima yellow. Also, who has the best prices on them? Checked out ebay and most end up being the same as local once shipping and handling is added on. Thanks!
