Sounds like yu have a shorted cell or two so the voltage never gets high enough trip the charger circuitry to turn off. This is why it is a good idea to also have a timer to prevent such things from happening.
Don't waste your breath on shielding Paktrakr, its useless. Noise doesn't come from air, it comes from wires themselves. I did everything there is to fix my PakTrakr. The only fix is to remove it and use something else.Maybe I'll throw the Pak-Traker back in and sheild every wire... if I get the batteries back from the dead.
It's my understanding that FLA sinks about 20% per year of age, which might be the effect you're seeing. That's just what I've read, not personal experience.have an Elcon PFC 1500 which seems OK after about 100 charge cycles. I do, however, find that I need to occasionally charge some of the six batteries individually using my nominal 12V Ctek charger. This keeps the resting voltages much closer to each other, which must be good. My range has fallen after 650 miles. It is as if the Peukert constant has increased. I have also noticed more voltage drop under load now than I had in the early days.
I don't think I did my pack any favours early on by running it down to virtually flat in a number of hour long drives.
I would advise anyone with a new LA pack to be very carefull and never run it down too far.
I'm sure I read this same advice before I was on the road but naturally ignored it!
As for your pack I don't know if you could drain all the acid and replace it completely?????????????
At least you would then have the same SG in each cell.
Something doesn't add up somewhere, the PFC is a great charger. How many batteries, what was the voltage setpoint at, what is the dipswitch configuration, etc. Which model PFC?
Sorry 'bout your problems...
bummer.... lead-acid is pretty forgiving, but the last third of life are prone to death by cooking because the voltage may not get up high enough to reach the trigger voltage in the charger. As the plates sulfate, the charge cycle takes longer, self-discharges faster, and doesn't get as high. I know MINE ( a 96v pack of usbattery 8vgchcx ) stopped triggering the auto-off voltage after about 400 cycles or so.I've now overcharged my Trojan T-105's at least four times. I usually leave the charger to do its thing overnight, and twice I've come out around noon to find its still trying to charge the batteries, which are smoking, at 180 degrees F, and have dumped battery acid all over my driveway. I've re-filled them with water, but I suspect too much acid is gone. Some cells show no Specific Gravity at all, others show an overcharge.
These batteries are shot. I opened one up, aint pretty!bummer.... lead-acid is pretty forgiving, ...!
