What is memory effect of battery?

In general, liquid lithium and lithium-polymer battery is no "memory effect" for more. This can only NiCd and NiMH batteries have a very limited extent affected by the memory effect (inertia effect or battery).

Your battery is still functional, but only 50% of their original capacity. To avoid the dreaded "memory effect", a fully cycle (fully charge and then fully discharge) your battery at least once every 2-3 weeks out. By pulling the AC adapter, batteries can be discharged until the battery is empty. Thus it is guaranteed to use your battery is highly effective and accurate.
What is the cycle batteries?

Each time a battery is charged and discharged, we call it a cycle. In the process of charging and discharging will change the battery capacity and the number of this cycle is called a life of a Dell Inspiron 9400 battery.

Normally, a rechargeable battery has a lifespan of 500-800 or more cycles. Even more simply, that they can use for one to one and a half years time.

With the increase in battery life, you may notice that the battery is running less and less time. For example: In the beginning, the battery can supply your phone 3 days, but now reduced to only about 1 day. If so, you have to replace the time certain new battery.
