Original batteries

[jdollatari]

2018 replaced my battery at around 30k in early 2024 just based on age and our extreme temps in winter and summer

I don't know if there's any stock batteries left in the fleet from any 2015 or 2017's? I'll have to pay attention. What temps are considered extreme in Idaho?

[Wallythacker]

Doesn't Idaho see swings like 95F in the summer to -35F in the coldest areas during winter?

Replaced my 2015 (build date Sept 2014) battery in spring 2021. Car now has 137k, I think it had a little over 100k on it at that time. Bought a Walmart Value Power, which was about $50.

Inflation - Walmart Everstart Value Power Group 35 is $69.74 in my area today, but that is still a very good price compared to anything else.

Yes it is. I just bought a group 65 for my 99 Ford F150, $69. I have had no trouble out of the Value Power batteries, so far anyway.

Since our cars have a very mild sort of regenerative power function, the charging voltage is kept a bit on the low side. Because of that, the plus-plates may become phosphated a little early.

With that in mind, before you buy a new battery, it may very well be worth it to use the "rejuvenate" function of a modern charger. That should clear off a good part of the phosphate which will restore most of the capacity.
I recently tried that with my old replaced OEM Hitachi battery, and it is now almost like new. Could have saved buying a new one.

I got about 4 or 5 auto battery chargers. Mostly just from over time, and 2 or 3 just because it was something like, "buy this battery, get a choice of battery chargers." And I like'em so I did that deal a time or 2. Another was just given to me with my current murdersickle. Anywho - I have yet to see one with a rejuvenate function. Sounds like a good feature. Maybe it's not a thing, in the U.S....

The rejuvenate function is usually standard on modern solid state charges. That function applies a higher charging voltage, usually about 16V to the battery for at least a few hours. Today's lead-calcium alloy batteries need a higher charging voltage than the phased-out lead-antimony batteries. Charging with "rejuvenate" makes the battery acid fizz like sparkling water, and the fizzing bubbles remove some of the phosphate from the plus plates. That makes the battery perform better.

Generally speeking, batteries should be charged in a well ventilated place, because the gas produced is a mix of hydrogen plus oxygen, being highly explosive.

Have one hooked up permanently to the battery just for this.

Still OEM batterY 2023 ES.
