One UT1 battery to rule them all

[oil pan 4]

Well winter is coming. So I figured I better test my Nissan leafs 12v battery. I replaced it's group 51r battery back in summer of 2021 during the great covid everything shortage. Which turned out to be the worst time to get a lead acid battery since ww2. I couldn't find any AGM group 51R batteries anywhere.
I figured the Nissan leaf only has to turn on a few lights and close several relays and contactors to unlock the high voltage battery to start making its own 12v power. So I went with a smaller group UT1 AGM battery made by deka for motorcycles, side by sides, ATVs and riding lawnmowers.
The deka UT1 AGM battery is rated for 320cca so I punched that into the tester. Hit the test button and it said the battery made 370cca. It's still well above it's rated cca more than 3 years later. Yeah that's pretty good. Definitely worth the $150 I paid for it.

I should look up the specs on the 16V used in the Model 3. It looked small to me. I'm sure it's a fairly specific battery to be a 16V that fits in that spot, but by the same reasoning you mention, it shouldn't take a big CCA battery to tell an EV to turn on. I'm sure current draw can be a thing while sitting, but most EVs these days are smart enough to engage the big battery to keep the small battery topped up.

Sounds like you chose a solid option that has lasted.

Only 16v batteries I ever saw were for "racing" and they were kinda small.
I didn't know the Tesla used 16v batteries for their low voltage systems.
How dare they use anything but 12v.

I put in my Prius a regular lawnmower battery. Just like an electric car, this battery just powers the computers, then the high voltage kicks in and starts charging the 12v battery. There is no starter to need a powerful 12v battery.I think it was around $30. The battery that Toyota calls for was around $170, or $200, can't even remember. But I thought that I can replace this lawnmower battery 5 times and I would still be money ahead. Working just fine for almost a year now.
Sometimes you gotta do what you gotta do, and sometimes you just have to play with and improvise stuff. I like to make things work that were not designed to be together.

Yeah it was probably some kind of U1 battery. Regular U1 have screw terminals. UT1 is the same battery but with the stump style battery terminals most vehicles use.

The date on my deka UT1 AGM battery is August 2021 and as of this morning, a 44f morning it tested 300cca on my snap on tester. It's rated for 320cca, which it will probably do if it sits on an AGM charger for a few hours.
The battery was sitting at 12.1v so I'll pull it, charge and retest. It's probably at 12.1v because of the car it's in.

It's good you used AGM, I have heard that other EVs can go haywire if you use a lead-acid battery in them when everything is programmed for AGM.

For our Mach-E, you can order the Motorcraft AGM from RockAuto for $143, but kind of wondering what they charge for shipping on that. Where did you get your Deka UT1 battery?

My wife ordered it for me off Amazon. I want to say it was like $80 shipped.
