I bought a rebuilt battery when my Die Hard finally died hard. That rebuilt battery lived longer than the Die Hard it replaced.
Ask your local parts guru about rebuilt/reconditioned batteries.
Face is the one who needs the battery. My Interstates lasted an especially long time in the desert, and the extra expenditure was cost-effective in the long run. When I need a new battery, I’ll most certainly follow your suggestion re: rebuilds. (Didn’t even know there was such a thing.)
