red ball on one battery

[043506.06speed]

I checked my batteries today and the passenger side shows a little red and white ball and the drivers side is green. So I checked them with a load tester and they held up good then I got a hydrometer and all 12 cells showed they where fully charged. Go start the truck and it fired right up. 30* out. Batteries are 5 years old. I think I'm going to Ignore the "eye" and keep them.What do you guys think? Am I taking a chance of getting stuck?

When you load tested them did you disconnect the cables so you weren't pulling from the other battery?

At 5 years old your pretty much at the life span of a battery, to me replacing them is cheap insurance that my truck will start when I need it most.

Yes. I disconnected the drivers side to move the cover and check the water level and do the hydrometer text.

They are not going to bad over night, or someone please step in and say so.... I would run them for a bit more, and consider it $$ in your pocket....

Those indicators aren't accurate. Did you hold the load for a few seconds? If you did then I wouldn't worry about; however, they are 5 yrs old so I would keep an eye on them and be ready for new batteries.

I held it for 10 seconds and the needle moved just a little bit. I have a battery pac/booster pac I think I'll start to carry it if I keep them. I like to see how long they last so i might just keep them.

Yea they are good for now. I would just keep it in the back of my mind that batteries are on the to do list.

At five years, you're not even close to done with those batteries, if your charging system has no faults. You'll see a voltage drop if a cell dies, and when it does, then replace it.
