That 3) might be my problem...
I'm using my JBR 99% in the car with a self build car adapter that supplies
8.9V (stab.) with load.
I have a Diesel car, so I'm not able to switch on ignition immediately.
So it goes like this:
- ignition on (motor not running, only glowing) -> JBR switches on
- wait more or less 2s (sometimes more, if I e.g. program the navigation)
- start motor -> 12V car voltage breaks down and comes up again
After that it takes a while and the JBR shows the battery with '?'.
Sometimes it then starts to charge (I guess if I started the motor shortly
after switching on ignition), sometimes not.
If you think in this procedure, 3) could cause that my batteries are
sometimes not charged ?
