You need to put juice back into them before storing and are these 4 or 6 cell? I put 8 minutes back into them and let them sit until I am ready to run them - then I tray them to 0.9 volts and let sit for 5 minutes then juice them. Peak volt detect at 0.03 - higher I was getting the packs really hot.

If 6 do not take them down to 4 volts - killing the battery off.

The newer packs today that I have ran perform a lot better with matched cells - when not matched they tend to vetn and overheat which kills them.

Hope this helps some.

Battery maintainance is SO FAR over marketed it's rediculous.

Equalization is bringing each individual cell down to the same voltage !

I won't get into which tray , this and that.

Different voltage points for equalization will give your batteries slightly

different characteristics .

Even the old low voltage trays won't cause any harm if used properly.

Comment for those who Dead-short ,,,,, after you bring your pack to 0.0

per cell and then put a wire from neg to pos. ,,, check your individual cell

voltage when removed from tray ?? That's where most the harm is done

as some cells will be in a neg. voltage state.

SAVE YOUR MONEY FOR BATTERIES , FORGET THESE OVERPRICED DISCHARGE / EQUALIZERS :thumbsup:

negative voltage state you say? ya gotta flip the wires around on your volt meter for every other cell or it will read negative. lol
