2014 CR-Z, Base, CVT
Hmm... Wonder if they were using crappy batteries. My 'Z has a battery dated July 2017. 3 years isn't a good lifespan for a battery, especially considering that the one in the 'Z hardly gets used since the IMA motor is what starts the car.Second year I Owned The Speed Bump the under hood battery failed and was replaced under warranty. The Honda dealer installed battery is still in the car today. The replacement battery had no "eye"
I actually wonder if a deep-cycle or a marine deep-cycle battery would work better. This would allow you to leave the headlights and radio on with the engine off without damaging the battery. Might be useful for a few people, at least.
