So I have an opportunity to get a bunch of napa 8146 225ah batteries for 50$ each. They are brand new never used still in boxes. Even though they are new they have been sitting in storage for a year maybe year and half. My question is are they still a good? What should I check when looking at them? I won't be using them till this summer for my off the grid house, should I just wait and get different ones when I need them? I need to make a decision by Friday so any help will be greatly appreciated
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.

8146 is the model number. It's government surplus so no warranty. They have 180 of them that have been in climate controlled storage no charging still in the boxes. Ii was going to check with a multimeter for state of charge. Should I pass on ones that are below a certain percent?
