NiCd discharge question
August 7, 2009
i have any questions about the topic
when a nicd cell have to be recharged? i am taking about voltage... 1,15v? 1,10v? 1,05v? 1,00v? per cell
i have a 3xcell batt pack in a bot , the system self recharge when the voltage reach 3,4v, so 1,13v per cell
is it an insufficient discharge? which can bring to lazy effect?
assuming that X is the ideal voltage per cell to decide to recharge..... have i to read X when the battery is under load or when it isunder no load.
I am asking this question because i have noticed that a almost discharged cell have very hi internal resistence so, it can provide 1,2 volts with no load and 0,9 volts when under load... so i am confused about this behaviour because i do not know in whick condition i have to read the voltage in order to decide is go or not for a reload.....
anyway the problem is that under full load tha batt pack have not to drop under 3,4v, so i fear i amgoing for lazy efffect issue,
yep the time between 2 consecutive reloads is dropping every time :\
