H700 battery not charging
I have an internal H700 controller in an R410 purchased in 2011; I just upgraded the drives from SATA 7200 to SAS 6G 15k, but I noticed the cache was in WriteThrough mode. Upon further investigation, I saw the battery had dropped below the warning threshold capacity. I ordered 3 new ones (actually, they appear to be refurbs.....the Dell sticker has a mfg date of ~late 2015, but the MegaCli command reports a manufacture date of 2007). After installing in the first server, it started a learn cycle as I expected it would, but said at the time the expected time to full recharge was around 20 hours....quite a bit more than the 4 I've seen other people report it "should" take. Now, ~4 days later, it appears to have stalled, and is neither charging or discharging, and the state is unknown:
BBU status for Adapter: 0

BBU Capacity Info for Adapter: 0

I update the controller firmware to 12.10.7-0001 (from 12.10.1-0001) last night, and after rebooting it was in a charge period for a bit, but this morning it appears to have only reached its current 37% (remaining capacity has been at 469 mAh for awhile now). Anyone have any thoughts to try to get it to charge? I'd like to not have to go through the process of returning these, especially if they aren't bad and this is just a configuration problem.
Thanks in advance.

Hello.
Reboot the server and then try to manually force the battery to begin the learn cycle using this command: omconfig storage battery action=startlearn controller=ID battery=id. To obtain the controller ID use omreport storage controller command and for battery id, use omreport storage battery controller=ID
Cont:

Let me know how it goes.

After rebooting, it started charging on its own. The charge was running for about 30 minutes, and then the status reverted to unknown:

Should I still initiate a learn cycle, even though it started to charge after the reboot (and reported the Learn Cycle Status as "ok")? If I can avoid putting unneeded cycles on the battery, I'd like to.

Power down the server and re-seat the battery and controller and then reboot. If the it does not fully charge, then restart the battery learn cycle and see what happens.

The re-seat of the battery cables (or just the passing of time) seems to have resolved the issue. Thanks.
