I still vote optima. Yes they cost more but they last like 8-10 years. A lot of people say that they're not as good as the used to be but I haven't seen it. If you buy from advance auto online and do store pickup you can search for a good coupon and probably get $50 off. Just google Advance Auto Parts Discount Code.

I've had a yellow top for about 3 years and it's in a vehicle that only gets driven about once a month. No problems to speak of. We've got red tops at work that lasted for 10-11 years and that equipment doesn't get used that much. I have been very impressed by their resiliency.

Parts Guy at the dealer told me a while back that the older Tundras had OEM batteries that were manufactured by Panasonic. He said that they could order one of the OEM Batteries but they cost something like $800. The replacement batteries that they sold over the counter were re-stickered Interstates. I ended up going with one of the restickered Interstates because $92 OTD.
