Replacement Acer Aspire 7520 Battery, High Quality Aspire 7520 Battery

What can I do to make my Acer 7520 Battery last longer?

There are several things you can do to make your Acer Aspire 7520 Battery last longer:
1.Choose the right battery. Under the same use conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
2.Use the notebook's power saving controls to reduce battery use in your normal day. For example, turn the Bluetooth off if it is not needed; reduce the screen brightness when conditions permit.
3.Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow it to warm up/cool down before use and before charging.
4.Contrary to last decades' batteries, modern lithium ion batteries do not need to be fully discharged to maintain health.
5.All batteries wear with use and time. When you find the runtime is no longer satisfactory, it may be time to purchase a new Acer Aspire 7520 Battery.

What is the "Memory Effect" that I have heard about?

NiCad batteries, and to a lesser extent NiMH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, Acer Aspire 7520 Battery "forgets" that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity. The way to avoid the dreaded "memory effect" is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks. Batteries can be discharged by unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will insure your Aspire 7520 Battery remains healthy.
