Customer Review: Got this for a 2005 Mustang GT. Fit perfectly. It has WAY higher CA and CCA ratings than the Duralast Gold it replaced. I’ve ALWAYS went with Optima because they last forever. Yes, they are expensive, but they are TOUGH, they don’t die on you if you happen to let them drain dead overnight by leaving headlights on.
Customer Review: I just replaced the Optima Battery I installed Sept. 26, 2016 with the same one, on Nov. 13, 2020. This Battery probably would have lasted longer but my Alternator failed and I drove the car home 15 miles on just the Battery, 3 weeks after I replaced the alternator.

Customer Review: I have had this battery for 18 months now, and I’m very happy with it thus far. I’ve been using AGM batteries in my work for quite a few years (stand alone solar powered automation and control systems) and they are very good performers when treated properly. I’ve seen them last as long as 7 years in some applications.

When selecting the best battery for your 2002 Toyota 4Runner, several critical factors determine performance and compatibility. The most important considerations include physical dimensions to ensure proper fitment in your vehicle’s battery tray, CCA rating for reliable cold weather starting, and reserve capacity for extended power delivery.
