    The thing most people miss is that the lifespan rating on most batteries isn’t the time until it’s completely dead and useless. At 10yrs/100,000mi the battery is usually rated to retain at least 80% of the original capacity. Most testing I’ve seen shows ~85%+ remaining after that. (So long as it’s not an air cooled battery like early Nissan leaf)
