    Best bang-for-the-buck over lithium and is a top quality battery with excellent reviews all over social media

    Installed it last week in my Challenger SRT8 and works great, but I especially like that it was 26lbs less than the standard battery it replaced and is the best bang-for-the-buck over lithium. Another real plus is that it actually weighed 19.2 lbs, and love it when a company understates their products. I can most definitely recommend and won't be disappointed.

    Braille B3121

    This 20 pound battery had no trouble starting a dead cold 7 litre in my C6 Z06.

    Disappointed and overpriced.

    Does not fit nearly as well as an Odyssey 925. It looks like a rebranded Deka at twice the cost. The 925 terminals look thought out whereas the 3121 look like an afterthought.

    Better than I expected

    I was having issues with oem battery, and wanted to buy something better than oem and came across this gem and I love it to death!
