I just bought a low mile 2017 base model and I'm still checking it over. Can anyone tell me where it says on a Delco battery when it was made? I suspect it may be the original.
Also if I need to change it what do I need to know about all the electric connections on top. I have never seen that before on a car. Do I just disconnect everything and move it out of the way? I know about re-indexing the windows and the clock. Thanks for any help

 

Not sure where the date) is but here is a description of decoding the date on the label:

There is a sticky at the top of this forum with instructions for changing the battery:

DIY, FAQ's, TIPS and Announcements > How to Replace The Battery

 

I just changed out the original battery on my low mile 2016 this morning. The manufacture date was (laser?) etched on the top of the battery in the black plastic. Mine was made on 6/1/2016, that is day, month, year. My car was made on January 16, 2016 so the battery would have been manufactured on January 6, 2016 per the battery top etching.

There are many threads on how to change the battery. The hardest part was getting the original battery out of the "hole" and it was very easy. My top post battery carry strap couldn't grab the battery terminals, so I looked around the garage and found a forgotten roll of Gorilla tape. I took a couple of about 2.5 foot long pieces of tape and formed a loop handle above each terminal by sticking the gorilla tape on each long side of the battery and leaving a loop handle above the positive and negative terminals. I also insulated the positive and negative battery terminals because.....electrical safety! I grabbed the loops and the battery was out of the hole in and on the cardboard covered carpet about 5 seconds of careful maneuvering by the cables that were taped safely out of the way. I removed the tape handles and safely carried the battery to my work bench by hand. If you choose to use this method it is at your own risk!

 

Deleted an unintentional double post.

 

I have never changed the battery yet on my 2019 but what is to prevent you from using two vise grip pliers and pulling straight up and getting it out that way. That seems easy enough and what I plan to do.

 

Have the battery tested to see its health, but if in doubt its age, might be a good idea to just replace it. Sure would not want to get stranded somewhere.

 

ZAP, maybe?

 

I changed my original battery (2016 mfg date) last year and pulling straight up did not work well for me as the battery kept catching on the sides to get fully out. I found it alot easier to pull up on the positive side of the battery and drag the negative side on the bottom until the battery was vertical with the positive side on top. To install the battery I just reversed the process. Just my experience.

 

Changing the battery on a C7 can be a little tricky, especially if you have to reach over a Stage 3 aero rear spoiler,

Here’s a good walk through video.

 

I didn't see the small black wire everybody has trouble with. Also, you don't have to take the L shaped bracket apart. Just remove the one nut that holds it to the battery, then the pos hold down.

 

That's what I needed. Thanks

 

I changed mine last weekend. Original battery had the date code on it like mentioned above. Not too hard to change the battery. The most difficult is getting the battery out. I just looped the strap part of a ratchet strap under the middle of the battery. Squeezed the strap with my hand to make it tight and used it to lift the battery with a little wiggling. In and out in 15 mins.

 

You got over 8 years on a battery?

Hell, I get nervous after year #3.

Change it out as part of routine maintenance.

 

why, battery sits in the back without hot/cold cycles experienced in the engine compartment??

 

My girlfriends 2013 Hyundai Elantra GT that she bought new in 2012 is on it's original battery. That's 12 years and still going strong! We have no plans to change it until it dies.

 

I was able to pull the battery out by removing the plastic vent elbow near the top on the fender side of the battery. Also easier to install before installing the vent elbow.

A nice set of terminal straps also worked but was very careful to support by hand as soon as possible.

 

I bought the garage kept car this summer from an elderly gentleman that only put 1800 miles on it since he bought it new in 2016. I bought a replacement battery and just for fun, I load tested the original battery yesterday on a resistive load bank and it passed as though it was new. It's on the recycle pile now.

 

Thanks to everyone who chimed in. I have it figured out now. One of the things that was throwing me off was my distribution block is missing the cover and when I looked at the videos they had the cover and I thought they were for a different year. This is the first car I have had with a distribution block.

 

Better to change it a bit early than too late.
Getting it out is a pain in the a&&. G M engineers , I bet, never tried ti get it out.
Yes turning it end up seems to be a better way to get it out.

 

As you can surmise, an "Advanced search" across the C7 Forums will find a LOT of threads dealing with batteries. HOWEVER... be aware that all the vids and PDFs offering instructions are NOT created equally, as I found out a few months ago when changing my 7-year old OEM battery. Do not, and I mean DO NOT disassemble that entire mess of BS on the positive terminal! Many have had trouble getting it to make adequate contact everywhere it needs when reassembled. Though a little bit of a pain to leave the "L" plate and so on as is, and move the entire thing disconnecting only from the post and the red-cable connector, doing thusly should guarantee the thing will work first-time when reassembled. All the best.
