    Last month I bought and installed an Optima YellowTop Prius replacement 12v accessory battery last month.

    Unfortunately, I damaged it during installation. (For details and photos see my post from back then.)

    I've bought a new negative cable, so now I can properly install a new 12v battery to replace the one I damaged.

    One lingering question - I checked the state of charge for if that new battery before I installed it (and before I damaged it.) I used an Optima Digital 400 charger (OPTIMA® Battery Chargers |OPTIMA® Digital 400 and Digital 1200 12V Performance Battery Chargers)
    The brand new Optima battery only showed 75% charged.

    Is that normal? Or does it indicate the battery had been sitting in the shelf at Pep Boys for too long?
    If that's the case, how can I guarantee my next one isn't also old?
