I have a Freedom 25
inverter/charger controlled with a link 2000R monitor
and over the weekend I attempted to equalize my 200ah bank of wet cell batteries (2) 6 volts in series. The freedom 25
is a white case model if that is of any value.
Heres what happened. I am able to get the monitor
mode by holding the setup button then holding the volt and ah buttons until the E goes out. The red charge LED flashes indicating it is in equalization
mode but the battery
voltage stays at 13.90-13.95 and the current
stays low like 2-4 amps. I have everything else shut down on the boat as I did not want to fry anything. Was expecting 15-16 volts and some bubbling at the batteries. I let it sit like this for 30 minutes or so and nothing changed. Outside temperature was in the 40's F and the charger
has a temp sensor on the battery
bank. I tried resetting the link to factory defaults then reprogramming it for my battery bank. Got it back into equalization mode but it still never brought up the voltage beyond 13.95. Does this normally take an hour or more to get the voltage up? I seem to recall
on other boats that in Equalization the voltage is brought up to 15-16 volts withing a minute or two and then held there for some time.
So it appears as though the Link is telling the charger
to go into equalization mode but the charger is not complying? I RTFM for the charger and it says it can only be put in equalization mode via the link panel. Both the link and charger are of 2000-2001 vintage I believe. One last thing I was not able to take the link out of equalization mode by holding the appropriate buttons, it only wanted to come out by shutting down the AC power, although maybe I was not pushing the correct sequence? I tried a few times to no avail.
Suspect the link or charger? Any other ideas to try and get the charger to equalize? I did confirm voltage at the battery bank with a fluke meter and it agrees with the link.
Thanks in advance.
