old battery's

I hauled the other day a 95 dodge diesel home to take the engine out that was given to me.
This truck had been sitting without ever fired up again on the backfourty for the better part of 8 years but had still both batts in it hooked up and all.
They looked in decent shape and weren't bulging or cracked.
There was still a trace of voltage in them when i put the DVM on them so i figered what the heck, lets put them on the trickle charger for a couple days.
Today i tested them on my carbonpile load tester and to my surprise they both tested very good. :lol:

My batts usually freeze to pieces in the first winter when they run empty but these went trough at least 7 of them seemingly without harm
 
That's almost one for Ripley's Believe it or Not! But unexpected things do happen. A few years ago I bought a lawn mower that had been sitting for about three years, (and we all know that mower batteries are notorious for failures), charged the battery and ran it for two years before it gave out.
 
I changed the batteries in my boat a couple of years ago and I'm still using one of them around the shop. It's one of the high dollar Optima blue top marine batteries. Looked at the build date on it when I took it out and it was made in May of 05. It still holds a charge and cranks all kind of stuff around here. Its on my generator now. I bet I never see another one last that long. Worst are the 6 volt batteries in my old Fords they never seem to last over a couple of years no matter who I get them from.
 
A "Snapper" brand battery, in a Snapper 11 HP
rear engine rider lasted me 9 years ! Every winter
the mower was stored in an unheated machine shed,
and got down to -30 in Wisconsin"s Winters !
 
I ran a set of group 30 gel batteries in my 47ft boat for 12 years and then changed to glass mats. There were 6 gel cells and people in the marina installed them in their boats after I took them out. I believe it depends on the cycle life and the charge as applied to the batteries. Batteries seldom used can be kept for years if not cycled every day or more tan once a day. Optima's glass mats can be discharged to nothing, left set for long periods of time and then recharged to full capacity. I used commercial group 30's to replace the gel cells and I'l bet they are still gong strong 15 years later.
 
The telephone company use to run the same batteries on their switch gear for 50 years.
Just requires proper use and maintenance. Of corse quality is an issue to.
 

Of course the telco batteries were not subjected to high temps or jarring/vibrations. I used to install and maintian them 1 cell would weigh up to over a ton.
 
One thing I have noticed after using a carbon pile load tester is that in about a month the batteries that I test with it usually go bad. I'm not sure if it's got to do with the extreme load that is put on them with the carbon pile tester or not. But I've had this happen more than once on customers' vehicles so I quit using the carbon pile load testers and switched to the electronic testers. I haven't seen this problem with the electronic testers.

don't go around testing battery's for the fun of it, I only carbon pile test a batt if i suspect it is bad(which it usually is)
In this case i had no choice but to test them, in any case if they don't last it would not surprise me a bit with the history on them
