I have a Ford Mondeo L Reg Mk1, and the battery in it, isn't
holding full charge. I have ordered a new one, and hopefully
should get it tomorrow (Monday), however I'm unsure if its ok
to full remove.
If I remove it, will it not mess up the onboard computer, and the
built in alarms that came with it, and anything else that needs a
constant power supply? Do I need to remove the old one in a
set way? I have a boaster pack, that provides power to the
battery to start it, should I place these on the leads when removing
it, to keep a power supply going through?
Any advice very much appreciated.
IF you want to retain everything, use a booster (jumper cable) to a second
car. Use same rules you do when jumping car to start.
Second car need not be running.
Attach the positive to the shank of the positve cable connector or to the
terminal at other end of that cable. Make sure is is secure and wont pop
Attach negative to bare metal on engine.
Have an old discarded heavy sock or heavy rubber glove ready.
Remove or loosen battery hold-down to free battery
Detach negative term from battery first, then positive. Slide the sock or
glove over the positive and carefully move aside.
Attach positive first, then negative
Just disconnect the old battery, ground (earth) cable first. Install new
battery with hold down, then the positive cable, then the ground cable.
Reset the clock and radio settings; the OBC will re-learn what it needs
to as you drive.
