Cold kills batteries. Who's running sales right now?

I just bought two for my duramax from The Battery Tree in Kernersville. Price was fair and they have a lot of batteries.
 
Advance auto always has great coupons. I haven't paid more than about $80 for a top of line the battery from them in several years. Go to www.retailmenot.com and search advance auto.
 
Go to retailmenot.com. find one of the advance auto $40 off $100 coupons. Then go to AA website and order online with pickup at store.
 
Southern battery on 66 in Kernersville had good deals on some blemish batteries. Bought one a while back for my Jeep and its been good just sitting for weeks.
 
I think user @Cory had some 'refreshed' batteries for stupid cheap prices. I believe his last batch had up to 850cca for less than $70.

Edit...don't know his affiliation or who he works for though.
 
I still have same deal going 74 bucks with core.

20 dollar core charge

Used tires express
2509 s cannon Blvd

If there is an Interstate batteries near you they have blems for 50.00 and they will give you 5 or 10 bucks for your old core.
 
COLD DOESN'T KILL BATTERIES, HEAT DOES! you just don't know it until the cold engine is a biotch to get started.

I have been getting batteries from interstate as of late. They deliver to my work, and have been able to give me a premium battery cheaper than a wal-mart price. Just tell the delivery guy to sell it to me on a cash ticket and not charge our work account. I think group 31 batts for about 65 bucks, and one that fit the TJ was $78 and change

Not exactly but....the cold weather does slow down the chemical reaction inside the battery which results in fewer free electrons available to produce current.

Heat doesn't kill em either per se other than to expand the membrane and make the reaction less efficient.
 
I was reading something about extreme heat making some of the liquid in them evaporate faster or something. Overcharging will probably kill them quicker than anything.

I just put two new Optimas in my K30 and that jewel cranked up as fast as usual even at 8 degrees the other morning and I hadn't plugged in the block heater.
 
Now you've got me curious about battery chemistry. I understand that keeping them on the concrete doesn't actually kill them, but I have lost batteries to the basement floor before. Also anecdotally, I know batteries don't care for big temperature swings, and I seem to lose more batteries (and alternators) when there's either a hit or cold snap. Usually it's when a battery is already near or beyond its warranty, but weather always seems to be the nail in the coffin. Anybody know why?
 
Depends onthe type of battery but leads assume lead/acid to start with.

Inside the battery you have lead "rods" and they are bathed in an electrolyte that when mixed with lead causes a chemical reaction that emits free electrons.
Like most liquids the electrolyte flows more freely and is thinner at higher temps. In extreme colder temps the electrolyte can ctually gel and prevent the liquid above it from flowing down to the lead. What "kills" batteries on concrete isnt some magic reaction where the juice seeps out into the floor, but rather the concrete is significantly cooler than the ambient air because is it insulating by the earth below it. So a battery placed on concrete the Delta between the top and bottom of the battery is huge and the electrolyte separates and all the free electrons pool at the bottom away from the terminals where you draw power.

This is a very dmbed down description and if you start tearing it apart there are a few things I would say different but dont feel it necessary to type 5 pages :D...so back off chemistry gurus, EE and such (Im looking at you before you start Shawn)

Now smaller batteries like cell phones or consumer electronics (and increasingly in larger engine cranking bateries as well) if the rate of reaction was uncontrolled you would literally create enough free electrons and enough heat that the device itself would implode. So a "permeable membrane" is added between the two reactants to slow the rate at which they can hook up and play Barry White as background noise and make baby electrons...this membrane allows the "liquid" to pass through but only in small amounts over time. With theat the membrane looses efficiency and the solid gets flooded to fast. More on point however is a traditional flooded reactor battery he reaction just is not as efficient in hot temperatures.
 
Place in charlotte on old pineville road sells car/truck batteries for like $25 with a one year warranty. Right behind 4wheel parts. I think it called battery service and supply. That's all I run, even if they go bad after a year you still only paid $25 for it but the one in my jeep has been in it for at least 3 years. Gonna get a new one for my CJ sometime next week. Even boat batteries are like $30 or so, not bad to get a marine cranking and a deep cycle for $60 for both
 
Northstate battery off of patterson ave in winston is about the cheapest iv found. $48 after taxes for one for my k10.
