12V battery replacement poll

[B177y]

I chose "other" for the poll. I'll wait for gremlins or Ford app messages to start showing up then replace it.

I live it a mellow climate, not too hot and not too cold which batteries seem to "like". I also put over 30,000 miles/year so lots of DC/DC converter charging and lots of time on my EVSE charging, so the 12 volt is generally happy.

I purchased a load tester on the advice of a post by @RLXXI so I'll randomly run a load test or be able to do one at the first sign of a gremlin.

Well I can confirm in Western NY where we really don't get that cold (avg Jan high is 30 F) my 3 1/2 year old 75,500 mile original H3 is showing 100% SOH, 426 CCA (rated at 380).

My only concern is the number of charge cycles. If I don't drive the truck for a day and do a real short trip, the 12V will show a SOC of only 30-35% and my Viking Charger Tester will say the battery GOOD - Recharge.

Nothing too funky yet but I got the Discharge warning in the IP a couple times and the System Off to Save Power display pretty regularly on the center screen.

I do wish these H3s were more common like H4 and H5 AGMs. We've exclusively used H5 Weise AGMs on our family Hyundai and Kia EVs. $129 delivered. If that was the H3 deal, a new one would already be in the truck.
