HP G5 255 - Multiple battery failures

[ngstan]

We bought 30 - HP G5 255 laptops a few years ago for our company. When they arrived, we ran diagnostics, deployed the ones that were needed and put the rest on the shelf. I revisted said shelf today and discovered 6 of the batteries show 0% and Windows says it is not charging. I ran the HP PC Hardware Diagnostics and it always fails on the battery test. Here are the results from one of the batteries:

Am I going to have to buy 6 new batteries or is there something I can do to get them working again? I left one of them plugged in all weekend and it did not change. Thanks for your help!

The batteries died on the shelf so yes they will need to be replaced.

Not what I wanted to hear but figured that would be the answer especailly since the warranty period has passed. Thanks.
