Great! how long did your last car battery last?
As far as I can tell, it was 4 years and six months
That's pretty much what they last, did you buy the new one before the other died or you anticipated it was time to a  new battery because running out of battery charge while driving is not cool
Yeah it was dead, I guess, so I got a new one. 
Are you a mechanic or you just learnt how to put it in, I know is a simple task to do but some people are scare about the possibility of a short circuit 
I usually am able to do all the work on my 25 year old cars. 
wise person, spend less money and you are sure the parts are originals and the job is well done. The good thing is now you order online and have parts delivered just at your door. Did you buy the battery online 
I'm not sure you can. I don't ever remember seeing one. I go to Costco. It has saved alot of money
Oh sure you can..!! you can buy them in any store you do not need to go to the store, and you can compare prices and pick the one is more affordable and has better reviews 
Maybe, but the core charge is an issue. I have gotten three free batterys in the last 5 years at Costco as they were in warranty
