Hi all
I am from Australia, I might have something to add out of interest here.
2006MY06 Forester NA 2.5 - The car turned a little sluggishly on startup yesterday, which I noticed, so the problem has drained battery or battery itself has drained over 2 -3 days.
Started up this morning, hardly turned then clicking.
Checked volts - 9.4
removed neg terminal - did amp test but not a proper one with 16 gauge wire, just a bogus test to see if my multi meter was working - got 228 ma, which from posts above I assume is normal for an incorrect drain test.
reconnected battery, went and had a coffe looked on the internet etc etc
half an hour later just decided to get a final reading on battery volts- 10. 4 volts... hmm battery is rejuvinating itself? Maybe good after all.
Went and had a smoke, couple more coffess, looked on the internet some more.
I then decided to do another check, surely my previous checks were wrong,, battery reading 12.2 volts... hmm it really is rejuvenating.
Either way I have never seen a dud battery revive itself, which leads me to beleive the battery is ok?
Car still did not have enough juice to turn the engine over, though it turn do a couple of sluggish turns but not enough.
Only thing I did was disconnect the neg terminal, all I can think of is: --that it reset the computer, and maybe the computer had a short in it (bug) causing a drain?
or
--Battery broken - sitting around normal voltage -- usless under load.
Will be interesting to see if the battery charges itself to turn car over , but I kind of doubt it, and I am leaning towards, the second diagnosis, of broke battery.
