I swapped the battery on Mom’s KJ Liberty today. It started to fail on Saturday when it couldn’t start the engine and required a jump, even though it had started without issue just hours prior. After the jump the car drove fine for over an hour and then was parked, which tells me that the alternator could keep the electrical system powered and was attempting to charge. I checked yesterday and the battery barely had enough juice to drive the power seat motors, so this morning I pulled it out and put a new Interstate battery in.
Now, what I’m curious about is the age of the old battery. I wouldn’t be surprised if it’s older than the three-year free replacement period advertised on the label, but I can’t find a label with a date on it like on the new battery that I put in that says it was made in March 2020. Is the “C5" label the date code? Or would the serial number indicate it? Beats me. What say youse, Oppo?
FWIW, I picked Interstate because it was the only one available in Group 34 size. The other choice was Deka, if they had them in the size needed. I'm actually kinda surprised that I can get anything besides Deka in a local auto parts store in Berks County, PA.

“ Battery Age: Battery age is determined by the manufacturing date. A battery is considered “fresh” if it is less than 6 months old. Most date codes are stamped on the battery case or label and begin with two characters, a letter and a number. The letter corresponds with the month the battery was manufactured (A for January, B for February, etc.) and the number indicates the year (2 for 2012, 3 for 2013, etc.).”

Some have a sticker or painted stamp. Some stamp the plastic itself.
If you clean it off, do you see any other marks?
Anything on the sides?

A cursory google says C5 means it was made in March of a year ending in 5. It looks older than 5 years, but definitely not 15 so I’d say it’s a 5 year old battery. A little young for it to die, but not outrageously so.

Can't go cleaning it now since it's gone to battery recycling heaven, but between this and what jminer found it seems it was made in March 2015. Thanks!

Thanks! Yeah, I’m not worried that the battery died after five years on Mom’s car;
she doesn’t drive around a lot, so the electrical system doesn't spend enough time charging.

Big TVs need big remotes, man.

Makes sense, long times sitting with short drives between will kill a battery well before it should go.

Daaaang, that's old. I recently replaced the 6 year old 2014 battery in my car, which was also waaaaaaaaay undersized and possibly not originally installed in the car.

You could add a low amperage charger to the car. I’ve got two pigtails on my truck for that reason, two batteries and I can hook up my low amp charger and top off the battery overnight when needed. It’s pretty handy. Beats clamping the terminals. Might be something to look into. You could even route it so you can plug it in outside the car with the hood closed.
