Default How do you measure the voltage??

I've been reading up on most of the posts on battery maintenance and some recommended that the batteries be discharged and equalised to 0.9v and store them. But my question is how and when do you measure the 0.9v?

After the batteries are equalised to 0.9v (that's what most manufacturers claim) on a equalising tray, the voltage starts increasing the moment it is taken out of the tray and the voltage would not be 0.9v. If I want to measure the batteries and check if the voltage is what the manufacturers claimed to be, do we measure the voltage when the batteries are still in the tray or when they are taken out?

Any comments ??

i think u measure it while it is discharging....0.9 cutoff so when it reaches 0.9 during discharge you stop...the voltage will always increase after cutoff so i dont tihnk thats the way you do it.

when i hook my packs to the bulbs i disconnect when the meter reads around 5.4V, thats how i do it...
correct if im wrong

Also, using a discharge tray will help bring all your cells down to the same voltage. The Novak tray works well because you can set the cutoff from .1-.9 volts per cell.

What I do is use an Integy 30A discharger which supposedly drops the pack down to 5.4 I then use integy / eagle racing saddle pack individual discharge/ equalizer tray which drops to .9 volts for each indvidual cell independently (hence equalizer). There's even a conditioner fuction that drops the pack to .5 volts The voltage will rise once you measure after the pack is taken off. Measuring during the discharge cycle is your best bet if you have no means of an automatic cutoff function.
