I'm finally at the point where I need to replace the battery in my track-prepped 370Z, and after killing two standard batteries in the past year thanks to the heat and the car sitting for weeks at a time, I'm thinking I need to step up to something more serious. The car has a few electrical mods and the parasitic drain is enough to flatten a normal battery if I don't keep it on a tender, so I'm looking for something with real durability and deep-cycle capability. I've been reading about the Optima RedTop with its SpiralCell Technology and how it handles vibration way better than a standard flooded battery, which seems ideal for a car that sees the track and some spirited driving . I'm in Emirates Hills and I'm trying to find a premium Optima battery for performance cars in Emirates Hills or somewhere nearby that actually stocks them, because I'd rather pick it up locally than order online and wait. The specs like 800 CCA and 50Ah seem pretty decent, plus the AGM design means no messing around with acid top-ups and it's spill-proof which is a bonus if I ever have to mount it in a weird position . Has anyone here actually run one of these in a modified car and can confirm if it holds up better in our summer heat than the usual brands? Also, do these mobile battery fitting services around here carry Optima or is it more of a specialist order kind of thing? I'm trying to sort this before the next track day so any real-world feedback would be massively helpful.
