Weak batteries?

Weak batteries?
The last week or so I have noticed the voltmeter on my truck is getting lower and lower when I first start it up. It is now at the lower line of "normal" when the gps are on, and it cranks weak but still starts. The batteries are about 1.5 years old motorcrafts and seem to be leaking from the top. My originals lasted about 5 years whats going on? I called up the dealership to have them load test the batteries to see if I could get free warranty replacements but now they want to "inspect" the entire electrical system . Do you think it is just weak batteries?

In my 97 I had 2 motorcraft go bad in just 9 months. I got new ones under warranty and now are fine, but they are only about 6 weeks old. Time will tell. I had 2 Dekas go bad in my 90 in about a year. I also had a Deka go bad in my Expedition in about 2 years. But other people have great luck with both Deka and motorcraft. Just the luck of the draw I guess. The charging systems are fine in all the trucks.
Do you know you are charging ok? Let them test it. If there is something wrong you want to know about it.

i have only had that happen from too much bouncing around, inverted position(dont ask lol) and over chanrging and they got boiled. you could test with a multi meter to see what your alt is putting out running and test the standing voltage not running, but could just be that your alt over charged them. they will let you know what went on when they test it forsure though

Weak Batteries
Thought I'd toss in my two cents.
I've had Motorcrafts in my '97 for four years, and they were there when I bought my truck in 2002. As far as I know, those batteries were there for AT LEAST four years.
We joined Costco awhile back. The Optima batteries had a max of 800 CCA. Believe it or not, the Kirkland (Costco) batteries have 950 CCA. I was skeptical, but went with the Kirklands.
Startup is much quicker and the engine turns over very smoothly. If you or your friends are Costco members, it wouldn't hurt to check them out.
I've had the Kirkland's since the beginning of October and am very happy with their performance.
BTW...the batteries cost around $57 plus a $5 core charge. I returned the old Motorcrafts and received two, $5 bills.

Took it in today and the dealership didnt come up with anything. They load tested both batteries and they were both around 700 (I'm assuming cca). Checked the alt output and it was fine.
This morning when I turned on the key for the gps the voltmeter was just a hair above the lower normal line, let the gps stay on for about 30 seconds and started it. The volt meter went all they way to 8 and sounds very weak, it starts up after about 2-3 turns of the starter. I'm going to check the battery fluid level and look around for rubbing wires. If you guys have any input let me know.
Just checked water in batteries and both were 1-2 cups low. filled them up and cleaned both post connections on each battery, then turned the key on to see where the voltmeter is, and now it stays at the "N" in normal and wont drop in the red zone when I start it. I guess I need to "KISS" (keep it simple stupid) more often. Thanks for everyone input
