Hello,
The original factory battery in my 2013 focus seems to be weak, even though it's only 2.5 years old. The voltage bleeds down to 11.8 V after about an hour after parking it. I have a '95 Tbird in which the battery is 7 years old and it holds up about 11. V for a couple weeks.
Interesting thing is both these batteries measure exactly the same on a hydrometer -- exactly on the line between the white and red, which I think indicates a pretty weak battery. I expect this on a 7-year old battery, but not on the 2-year old one.
On the Focus, the battery is in a box stuffed up against the firewall and the back half is hidden under the cowl, so I cannot even see, let alone access, the rear 3 cells. It looks like quite a bit of dis-assembly and removal of other stuff in front of the battery box must be done in order to get the battery out of the vehicle.
Has anyone here done this, and could describe how....? Or direct me to a source of such info...?
Thanks much for any advice...!
