    This is what the shop that tested my battery said. I do not think this is all that low, what are your thoughts on this?

    My last battery was an Optima and it finally kicked the can with less than 10 CCA on the battery.

    I'd run it until it starts to struggle.

    Cold Cranking Amps is a useless unit of measure, in my opinion. Still, if that's the unit we're using, you're still at 76% capacity. Throw it on a battery charger and you'll be good to go! I use a Genius G3500 to keep my battery topped up.

    I actually have one of those, and I have recently had to charge it after driving a few miles on a dead alternator at night.

    I've had 2 genus chargers. Worst junk I've ever owned, the best of the 2 would only top off a battery, wouldn't charge at all if it was close to dead.

    the issue is how old is the battery? In my 40+ years of driving I have never had a battery fail at a convienient time, so, having said that, they get replaced every 4'ish years regardless of how they test.

    Your least favorite cousin comes to town and you loan him your older vehicle... THATS when the questionable battery fails. The dumbshit gets a jump and the knuckleheads cross the cables... I have heard lots of stories like this from my "customers".

    Interesting. I have not had issues with it, but a dumb charger might be better for severely discharged batteries.. or an extra battery hooked up in parallel to wake it up. I have heard of people needing to do this with many other types of chargers that wouldn't "see" the battery too. The one I have seems to maintain a charge at or around 12.8V. I needed it to do that because a battery tender plus wasn't charging my motorcycle AGM battery to the required 12.8 volts, but rather it was going to 12.6 and stopping, which eventually killed it.

    Def not loaning my truck to other people lol... I also have a battery pack jump starter in my truck at all times. The battery is probably about 4 years old. The one before it was an Optima that lasted maybe 6-7 years

    Yep, the first one wouldn't charge at all, almost full to dead, nothing. Exchanged it. The 2nd would only start charging if the battery was above 12.4, pretty much full. Anything below that it would flash errors. Hook up to an discharged battery, hit it with a dumb charger and it would kick on. Tried repeatedly to talk to the manufacturer both times and got 0 response. I couldn't find the receipt for the 2nd one, chucked it in the trash and have been talking smack about them ever since :laugh: $75 to do what a $2 float charger from hf does is a bad investment.
