subject: the "memory effect" in the battery terminology [print this page] Often hear the "memory effect" in the terminology, which is why many HP Laptop Battery IBM Laptop Battery people in charge when one of the problems encountered. That is how in the end it all about? "Memory effect" refers to a battery of chemical substances produced within the process of crystallization of an effect. Generally occurs in Ni-Cd batteries, Ni-MH battery less, lithium had no such condition. Occurrence is due to repeated part of the battery charge and discharge is not entirely due. It will reduce the capacity of the battery temporarily, resulting in reduced talk time. APPLE a1185 battery APPLE A1189 battery
Battery memory effect how to avoid them? Players should no electricity battery to recharge, do not have to repeat battery charge. To fully discharge the battery must be placed about 24 hours standby battery fully discharge and then fully charged. Cycle so many times, you can restore the battery capacity (unless the battery is damaged). Of course, to completely avoid this phenomenon, or NiMH batteries or lithium batteries buy better.

Not more than 24 hours per charge, and battery power when there is residual try not to repeat the charge, also best not to use the charger in the discharge circuit to discharge. Because the existing charger attached to the discharge circuit has been the phenomenon of discharge, will cause the battery of chemical damage to shorten the life of rechargeable batteries.
Ni-Cd batteries have a strong memory effect, very easy to charge and APPLE A1079 battery APPLE A1175 battery discharge due to poor reduction in available capacity. Usually need to use 10 times to do a full charge and discharge. If there is memory effect, then you can do three to five consecutive complete charge and discharge to free memory effect.
