Mine used to show 13.00ub with engine off and about 14.00ub with engine running about 2 months ago (last I checked). Now it reads the same with engine running but with engine off it's more close to 12.60ub.

Probably means that my battery is on it's way out, no? It's been a little over 3 years the last time I replaced it.

BTW, function 09 on the OBC is "system voltage at terminal R"...anyone knows whatever that terminal R is?
