Optima YellowTop battery since 5/07
Recently if I just play radio (engine off) for just under 10 mins, the
car won't start. Is it because it's not being charged ? or is the
battery a goner - Is there anything I can do to revive the battery ?
Normally my Z4 stays in the garage until the weekend. Then I started
driving it every day to the P.O. and back (10 mrt). Then one day it
didn't start. I took the battery to the parts store and they checked it
out for an hour. It was O.K. Then I contacted the BWM shop and took it
in. Again it checked out O.K. The mechanic asked about my driving
habits. He said I had a bad driving profile. The battery would be
drained a little during non-use and more upon start-up. I was not
driving far enough to charge it back up. He said he has had this
discussion with people who buy a new 7 Series and come back a month or
two later complaining about a dead battery.
Anyway, I bought a trickle charger for $70. I connect it and it "tops
off" the battery every 2-3 days.
Never mind the battery - it kills an engine never getting to full working
temperature. Which it won't in five minutes regardless of what the temp
I have a charger bought from Lidl for 12 GBP. Charges the battery then
switches to a maintenance charge which can be left on indefinitely. Small
enough to just about fit in the pocket, but powerful enough to charge a
flat battery overnight. Very handy for my other car which doesn't get as
much use as my BMW.
