What affects the Batteries Memory?
Nickel Cadmium (Ni-Cd) and some Nickel Metal Hydride (Ni-MH) batteries are associated with the memory effect. Lithium Ion (Li-Ion) batteries do not have this issue. Many newer laptops use Li-Ion batteries, but older laptops may still operate with Ni-Cd and Ni-MH batteries. Changing the type of battery used in your laptop is not recommended and is usually impossible unless the laptop has been pre-configured to accept multiple battery chemistries.Ni-Cd and Ni-MH batteries have a tendency to stop fully discharging if they are repeatedly only partially discharged before being recharged. The acquired inability to fully discharge results in a decline of useable battery capacity, shorter charge duration, and decreased battery performance. For example, if you regularly recharge the battery when it has discharged 65%, the battery will forget it has the ability to charge 100% and only charge 65%, which means your battery now only has 65% capacity. A battery with a three-hour life would only run for two hours without AC power if it developed a 65% capacity memory.To prevent batteries from developing a memory, complete the conditioning procedure described in the How To Make Laptop Batteries Last Longer FAQ when you receive your new battery. You should fully discharge and recharge the battery every two to three weeks thereafter. In order to fully discharge the battery, unplug the AC adapter and allow the battery to remain on until it runs out and the machine shuts down. Save and close any documents or programs before allowing the laptop to shut down due to a low battery. Now you may recharge the battery.
