If it’s genuinely “unused”, they should give you a refund, but they might be jerks about it.
If you bought it by mistake, used it, and now realize you really don’t need it, that’s not their fault, and they could reasonably refuse to return it.
But if it’s genuinely defective, they should give you a refund, or at least a replacement, but they might be jerks about that, too.
It’s common to hear that defective batteries that Crappy Tire sold to someone, will miraculously pass the test. Make sure it’s a ‘stress’ test, and not just measuring the voltage with no load. If it’s the ‘add-water’ kind, they should be able to test the fluid in all the cells, too.
The Crappy People who post here say they’ll give customers better service if they stay calm and polite. It’s always a good idea to start out that way.
But customers who post here sometimes say they get a better outcome if they make a scene, complain loudly, etc. It might be worth trying if they are being jerks already.
Interesting about the sticker for 625 vs. 650. You should be able to tell from the part number or model number whether it’s actually a 625 or a 650. If you paid for a 650, and they gave you the wrong model (i.e, a 625) by mistake, you should be able to ask for a switch to the 650. Then you could rightly say, “Hey, it’s unused – give me a refund”.
Keep us posted!
Never buy from Crappy Tire ever again!
Their slogan should be, "No Refunds, No Exchanges”.
