Do Nimh Batteries Need To Be Fully Discharged Before Charging. You dont need to discharge NiMH batteries for them to be at their best and in fact fully discharging them may damage the cells. The New Generation of NIMH batteries do not develop a memory effect and can be recharged at anytime during usage cycle.

No NiMH batteries do not have a memory. Yes before you use your new NiMH batteries for the first time you must charge them fully. There is no need to discharge either NiCad nor NiMh prior to charging if you are slow charging 01C or very near that value.
Todays packs are usually assembled stick packs so balancing is out of the question.
So charging NiMHs when they deplete to 11V is better than waiting until they get to 10V. Todays packs are usually assembled stick packs so balancing is out of the question. Because of this it is recommended to do a 100 discharge every 25 chargedischarge cycles. The battery begins to discharge when the load is connected at terminals.
