I have a few of these used I'll sell. They come out of refrigerated trailers, when they need to be charged for whatever reason the company just buys new ones instead of waiting for them to be charged. $50
Another vote for Advance. A few months ago I scored a deal where they had batteries on sale, plus I used a30% coupon by ordering online plus it came w/ a $20 SpeeedPerks payback. I got a Platinum AGM for like $145.
Only downside is they don't have any models w/ both top and side terminals (which is convenience for winches etc). But for the $$ saved you can buy a nice set of couplers.

I work at Orileys one night a week (get a killer discount). But last night a guy came in to buy a new battery and his core looked brand new. So I charged it up and tested it...I just scored a new battery
The places that sell Used or rejuvenated batteries, say they majority they sell, were simply run dead. Faulty charging system, & the owners run & get a new battery!
