I have an ac delco battery 650 ccc,there is two #'s on the battery 63754 and j5nar which is the proper battery warranty # ??

This power pack is virtually unknown. Look on the back for a socket and connect a mains lead. It is likely a simple connector that looks like the figure '8'.

This says it has an AC Adapter and if yours is from 2013 the batteries will be shot.

Nov 3, 2013 - I have the manual for the ACDelco 34300 and I need the AC Adapter for it. If you can give me the DC Volts and Amps listed on the adapter, I can ... ..

parts store can give you the size you need from whatever brand they may carry..but a word on batteries..AC delco makes most car batteries along with national gould, a subsidiary of johnson controls..and there is interstate(which I personally dont care for).. now AC delco makes batteries for almost all the parts stores like autozone, advance and napa ..carquest usually carries the national gould ones as do most farm and home stores..walmart and such have AC delco batteries..all are ok..but most AC delco batteries last much longer and have more power than the others..you should be fine with one from autozone..but I would go with one a bit more powerful than what is called for..higher cold cranking power..my dadused to sell vx-6.. a liquid cadmium battery additive that was added into the electrolyte so it boosted the batterys' power and mechanical life in some cases over 150%..he taught me which battery types to stay away from..interstae was on the top of that list..his reason, they used recycled lead plates in new cases and sold them as new batteries..

AC Delco or Interstate batteries are the best......If you don't plan on keeping the car for more than 3-4 years then the Canadian Tire Motomaster Brand are very good as well with good warranty.....

just buy a quality name brand. AC Delco, Motorcraft, Mopar, Sears, ect. the longer warranty batteries do last longer. you may not be able to get a larger battery because of size restraints.

I don't know what people are thinking here...!!!
Anyway, you will notice that these black and red caps have little straps on them. This should give you the hint that they can come off. Don't be afraid to tug on these suckers until they come off. Then using a 10mm socket, remove the battery bolts, negative first. Then remove the battery strap. This battery is vented, so remove the tubing carefully so as not to damage them and get the proper AC/Delco replacement. Not cheap! Oh and remember to drive your car for about 30 minutes normal driving to reset the ECM. Also, if you have a password on your stereo, remember it, or disable this feature before you start, or you will have a useless piece of scrap for a radio!

I would use a Delco 6 year battery. It has a 30 moth free replacement warranty and 6 years pro-rated warranty. call 1800 AC DELCO to find nearest dealer,

Call the Chevy dealer, even if you didn't buy it new or there. Also, and I learned this from experience, once an AC/Delco battery has been run down, they very often never work right again. I have bought 3 replacement batteries over the years because AC/Delco batteries are junk (fine unless you run them down).

I highly doubt that the warranty is still in effect, but it never hurts to check. I would recommend contacting a Chevrolet dealer to find out what is still covered. If you do need a new battery, Autozone sells a good selection with a range of prices. Their warranty is also very good. They replaced a couple of batteries for me even though it was my fault they failed.
