Without this important treatment, you won't be getting the potential out of your battery's life span. Also, ensure that when you charge your battery, it reaches 100 percent. this method allows your battery to ‘learn’ how much electrical charge it can hold.

Not every cell will reach a dead status before the rest and this can cause live cells to flow current in the reverse direction of dead cells causing permanent damage.When I flew RC models, I had a special charger/discharger that would discharge 1.2V cells to 1.1V, so a 4.8V receiver pack was dicharged to 4.4V and a 9.6V transmitter pack to 8.8V. Using this method, when I sold my equipment some 4 years later, the batteries were still performing above their rated capacities.Now that was for NiCads which were notorious for developing a memory, but it should be noted that you cannot apply one technique to every type of battery out there. Since there are different methods of construction, they also need different methods of charge/discharge cycles. The most important being what voltage is a battery considered dead? 0V is not dead, it's garbage.
