I replaced may original battery in my 2008 Toyota Tacoma 2.7L with one of these in March 2013. I like the additional threaded posts a marine battery offers for connecting accessories like my stereo amplifier. The deep cycle functionality works for playing my stereo with my engine off without fear of harming the battery. Also as I worked overseas my truck would sit for 5 weeks at a time without use of a maintainer or charger and it never failed to start. This marine battery provides 690 marine cranking amps which isn't as much a 690 cold cranking amps but plenty for my 4 cylinder. I live in South Texas, I don't need CCA's. If you don't know the difference I suggest you do a little research, after all you are online reading this review now. Check the vehicle manufactures requirement. Don't pay for extra CCA's if you don't need them. They are for very cold temperatures and hard to start vehicles. After five and a half years of use it has become weak. 5 years of auto battery life is good and as good as the factory battery was. I went to Walmart today and bought another one. I Installed it and it cranked my truck right up. And don't buy old stock, there is a round sticker on the battery with a date code, buy the latest one on the shelf, usually at the back of the rack, this has worked for me over the years and suspect this is one of the problems with faulty batteries resulting in negative reviews. A very good battery at a very good price.
