Aside from not knowing what the "8146" implies, a key to your description is the "sitting in storage" part. If they were NOT charged, and were exposed to freezing temps, they may have been damaged ( cases cracked). If you get the normal warranty at that price, then it's still a good deal.
Check & see if they are (still) charged. Most chargers have an indicator of the battery condition. Check for cracks in the cases or leakage. $50 sounds like a good deal for most any "new" battery if they still come with any kind of warranty. If not, and they were uncharged and exposed to freezing - very risky.
