I recently had to upgrade my PS6210's and all of them had critical battery messages. I ordered 6 new batteries and got them replaced. Apparently they were not all seated well enough and some did not charge. Eventually I managed to get all 6 charged and all came up with a status of Good.

We have been working on rebuilding our datastores and VM's and now 3 weeks later every single battery is coming up with a status of: end of life critical! Is it likely that we received 6 bad batteries, or is it possible that there might be another explanation? The batteries were initially coming up with similar errors, but once they charged for 24 hours they showed Good.
