Aantonis,

if you equalise to zero volts and leave it there for a good while you will get way more run time (as compared to not doing that). Equalising to 0.1v hellps a little bit but you really have to go all the way to get full effect. And make sure you get as much as you can out of the cells. The charge Mah should go through the roof too, I generally put 4000 to 4300 into my cells on charge.
