  Those numbers are not reporting correctly or the battery has some issue with it. It is reporting that it is fully drained. Upgrading the firmware would be the first step and possibly reseating the cable to the battery.  
I noticed after restarting one of our servers today OMSA spit the following to the console: OMSM : Controller event log: Current capacity of the battery is below threshold: Controller 0 (PERC H800 Adapter) OMSM : Controller event log: BBU disabled; changing WB virtual disks to WT, Forced WB VDs are not affected: Controller 0 (PERC H800 Adapter) So I went to the web-based OMSA (https:// :1311 ) and sure enough the virtual disk writing policy is set to write through.  When I go to the battery Information/Configuration the status has a green check, state of ready and Predicted Capacity Status of ready (see screenshot).  I noticed I'm out of date with the H800 firmware (12.10.4-0001 vs. current 12.10.6-0001).  Before scheduling maintenance I was wondering if anyone has run into this situation or if anyone has suggestions?  Below the screenshot are excerpts from the lsi log.
