I ran the first testload for 24 hrs, and ended on 12,19v with the 60W+ load.
Now i've recharged the bank and connected 2 car headlamps at 55W each; total 110W, and ran the load at 15hrs. The voltage started at 12,75v and fell slowly down to 12,20v during the 15hrs.
Under the first testload at 60W, the voltage started at 12,65v, and fell to 12,35v rather quickly (1/2hour), so i think the bank are getting healthier now... ;)
I might run a third 'wakeup' cycle, to see if i can get it revitialized a bit more... :)
As i now have some storage, it's time to get my windgen project running... ;)
