Battery Eye Color
F-450 PSD. Both battery eyes where green, checked level in batteries and found all cells to be low. Owners Manual says nothing about color of eyes. Added distilled water to proper level as owners manual says. Put a low 2 amp charge on both batteries until charge turned off. Both battery eyes are now bright Red, what does this mean? Vehicle starts ok, batteries have a full charge. Called Ford customer service but no one could tell me what the colors mean. Called a ford dealer and was told that means the batteries are going bad! The vehicle is only 6 months old.
Thanks for any help you can give me.

Odd. I never put too much faith in those "eyes". Mainly because I'm not too sure how they work.
I do know that most reputable auto parts stores will LOAD (not voltage test) test a battery. It may be worth the $5 or so to test 'em before you go out an drop +$120 on a couple of new ones.

If the truck is only 6 months old, shouldn't the batteries be covered under the 3yr/36000 warranty?

I would have a load test done on the batteries.It only takes a couple of minutes to do and will give a good indication of what kind of reserve power they have.Which is the best indicator of overall battery condition.

Green is good, red is bad. If the truck is that new, definitely take it in for repair/replacement. Also have them check the charging system. One (or both- if so equipped) alternators may not be functioning properly.

Possibly the added water affected the way the monitor eyeball reads the battery, but the charging should have mixed in the water pretty good. Still, I'd drive it a few days and if it stayed red, then take it in under warranty.

Hey breezyacres!
This is on a motorhome Right?
Chk also that you don't have a constant trickle drain in your converter
if it is equipt with one.
I had a converter unit and charger unit that had a bad diode in it that
would leak to ground. Found out one day it the rain in a campground
got a nice 12v shock.Fleetwood changed the unit under warranty.
Am I assumming that these batts are also the house batts or are they
just to start the Motor?
Don't really know from your post.

An F-450 Motorhome? WOW--my dream motorhome. I just got back from a trip in my E350 motorhome and was constantly thinking about how wonderful it would be to have a SuperDuty body Class C motorhome. Why, I'd take that over a Class A.
