HP DL585 - Write Cache Battery Not Charging

I have a trio of HP dl585 servers making up a VM cluster. I recently replaced the write cache battery for the p410 raid controller in response to a sensor error showing it was bad.
Since then (2 days ago) the battery still shows "partially charged" when viewed in the Hardware Status tab.
This isn't highly critical, as our VM's are all stored on the SAN, but I still want to maintain functionality of the local drives to remain flexible in the case of some hardware problem down the road.

Anybody experienced this issue before? Is it expected for the battery to take days to charge? Is there perhaps something I need to do to initiate charging now that I've replaced the battery?

Any suggestions are appreciated. Thanks in advance.

I've had faulty replacements too. If the local drives are just for loading ESXi with though I would take the cache plus battery out and use what's left as a P410i/zero (RAID 0/1 only, no RAID 5 support). Not worth the cost of a battery for something that only writes updates when you change settings.

Yes, with duff batteries, what does the Array Configuration Utility, and Storage Controller start up state - Charging?

Erroneous errors can been seen from the vSphere Client/ESXi Host.

I'll have to power cycle that sucker to get to the ACU, but I'll check that out when I can. After hours...
