Couple of quick things:
1. The new battery is for keeps. I'll explain below
2. The battery seems to work just fine, and the basis for my question is simply that it seems wasteful to get rid of a decent battery (seems to conflict with the fact that I replaced a perfectly fine battery, I know.)
Easy....get your $5 and let NAPA take care of the recycling.
Seems like such a waste, thought it may be the route I take. I really don't need a battery hanging around.
I wonder if it would be beneficial as a backup battery. I could keep it topped off and use it fillin for a dead battery, while I look for a deal on a replacement battery. Could be YEARS, though, and I don't really want to have a battery hanging around for nothing, though....
Leave the old battery in the car and leave her a set of jumper cables instead. As you mention, seems like such a waste replacing a good battery. 4 years old isn't necessarily old. [censored], the current battery could possibly outlast the replacement you want to buy...
Besides, the jumper cables are a tool she can keep and use over and over. The battery you buy will need to be replaced at some point, and then she'll curse your battery and wish she had jumper cables.
Wow, pretty heavyweight censor on here...
Were I keeping the car, I'd maintain it and be perfectly fine driving it until it died. I've got chargers and a jumper battery pack we got for Christmas this past year.
The reason for buying a new battery (which will not be returned) is based partially on the responses in the thread I linked in my OP. If they are left stranded due to a dead battery (that is also NOT caused by a bad alternator):
1. They'll have a battery with a full warranty
2. I doubt they would complain if the old battery died, but with a new battery I have zero fear of it happening. If they do find it necessary to complain in an accusatory manner, I can politely and lovingly tell them to pound sand and refer them to item 1 above.
3. I do not want them to be stranded this winter, should the battery to decide to fail them at the worst time. Batteries are cheap. [censored], I'm selling them the car for $2500. I'm not doing any of this for my own financial benefit. It's for my peace of mind, even if they don't notice or care.
The censor is a bit ridiculous. I actually got a warning on here once, because apparently, even if the censor works, someone can quote you and see your swear. I don't know if this is still true, but it was probably the most ridiculous comments I've ever received. I don't remember how I responded to the mod, but I'm sure it was full of self-righteousness and sarcasm. haha
$5 is pretty low. All the other chains give $10 for old batteries. AAP was doing $20 a battery earlier this year, but went back to $10.
Aren't there occasions where batteries are purchased back, regardless of where you got them from for a price similar to what you mention?
