Notebook or laptop computers are fast becoming the primary hardware for users. Unlike the early days of personal computers, many people choose to own only a notebook. The debate over Apple or PC is still very much a topic when choosing a computer. Whichever you choose, bear in mind that each make of computer has its own specific battery but that the steps you can take to preserve battery life and efficiency are the same for all brands.
Apple uses lithium-ion batteries. There are specific recommendations on how to maintain your Apple battery.
- -Use and keep your Notebook in a proper environment. Apple Notebook batteries will perform best at 20˚C (68˚F) and in temperatures between 0-35˚C (32˚-95˚F) it can keep its high performance.
- -Using your notebook in an environment that is too hot or too cold can affect your battery performance and shorten its lifespan.
- -New batteries need to be fully charged before use. Make sure that your battery is fully charged during the first charge at home. Always update to the latest software as Apple will release new updates to help improve your battery performance from time to time.
- -Your lithium-ion battery needs to have a flow of electric current through it. In short, don’t leave it plugged in. Try switching to the battery as the source of power for your notebook to generate the electrical flow.
- -If you are not going to use your notebook for more than 6 months, Apple suggests that your battery should be at least 50% charged. This is because if you keep an empty battery for a long time, it will lose its charging ability and shorten its usage.
To use your Apple notebook battery to it highest potential, follow these steps.
- -Use the energy saver setting.
- -Reduce the brightness of the screen to the lowest level where it is still readable without straining your eyes.
- -Turn off your AirPort and Bluetooth if not in use. Leaving it on will waste your battery energy.
- -Close all applications that are not in use
- -Remove all CDs and DVDs from Optical Drive
- -Remove all USB devices that are not in use.
