Main battery discharge
 

I've noticed twince in 24 hours that my 'bars' suddenly drop from 3-5 to 1-2 in no time at all, engines comes on to charge it and then it seems to hit4-5 bars and all seems fine. I've only noticed this once before in 9 months of ownership. Any clues?

I had some similiar changes in IMA pack gauge when my 12V battery was dying. Pretty stable in the middle since the new 12V battery.

Does anyone have the hybrid accord service book? I'm real curious as to the intended charge profile for the aux battery and amp output capacity of the converter. I've set one of my SGII xgauge's on voltage back when I started having the 12V issue and find it to be much more variable than I would expect from a dc/dc converter and a new 12V battery.
