Put your Batteries in the Freezer? No Don't

Long story long. While putting in new headlights in my truck (sitting for months and not topping of the AGM battery) I got everything hooked up and noticed nothing came on when I turned the key to ignition.

Thought I popped a fuse. Spent half a flippin' hour checking all the fuses then had a grand idea. Hooked jumpers to a spare battery and everything works. The agm in the truck ran down to 9.4A.

Swapped batteries and brought the near dead one inside and recharged it. Actually, I brought all batteries inside and topped them off and will now keep them inside.

Just reminds me of my grandfather that put his smaller batteries in the freezer thinking they extended their life.

Really can't think of much more that will kill a battery than freezing cold temps. Now my wife is asking why all these batteries are in the house.

 

Forgot to mention it's 28F here

 

Really should have prefaced this with "I Fucking Hate Batteries!" I'm about to explode like a cheap lithium ion in a Samsung phone.

 

A good battery tender might be a worthwhile investment in your situation.

 

Are you sure he didn’t just put them in the refrigerator? A common thing back in the day of standard zinc-carbon batteries and it did prolong their life. Have to warm up before using them though. Not so helpful for Alkalines. Most manufacturers recommend you not store in the fridge due to moisture induced corrosion.

I've got two of those and use neither one. I've got so many bad battery stories I could write a thesis.

 

I know he put them in the freezer with his cash and morgan silver dollars!

 

You and me both it seems I buy a few new Batteries every year
