Check your OM. I dont know the algorithm, but I assume that if not entered right, the other values could be off.
Not sure if 20 min is enough time to properly get rid of the surface charge.
maybe you could check my owners manual too... I dont think it lists it.(looked 2x so far)
It lists a 48AH battery with no CCA
subaru 2011 forester manual
should work for a manual.
I did test my battery again the next morning after sitting overnight it tested 7.xx mohm 80% and 350~~ CCA
From what I read online these batteries are mildly terrible.
the MT gets a GREAT 48AH 4xx CCA and the auto gets boosted to a 52AH battery.. cant find real CCA anywhere so far.
It just so happens My grandma's car wouldnt start today in -5F
so I checked it out.(she missed her hair appt.. lol)
the meter said 12.21mohm, 50%
the cca was 245 (rated 650)
Replaced with a new battery.. and all is well again.
