battery life

Every day use Tips to extend your ACER AP18K4K laptop's battery life

1.Keep the ACER AP18K4K battery contacts clean: Clean your battery's metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
2.Do not expose the AP18K4K battery to extreme temperatures. Do not leave your battery outside in the cold or in your car in the summer. Cold batteries can't create very much power and hot batteries will discharge very quickly.
3.Don't pack your laptop away in a backpack or other enclosed space when the ACER AP18K4K battery is still warm, trapping the heat. A battery that is frequently hot to the touch will lose life a lot faster than a battery that isn't constantly being stressed. Worst of all: if your laptop crashes or refuses to shut off properly, the battery can get extremely hot when packed away in your bag.
4.Keep vents clear - don't put your acer laptop on a fluffy pillow or a cushioned service that will cover vents and trap heat.
5.Avoid allowing your device to discharge completely. Constantly recharging a lithium-ion battery does not shorten the battery life more than normal usage would. Avoid letting it sit on empty for too long; instead, keep it charged-up if you can.
6.Chargeable batteries will wear down quickly, when they are only charged for a short period of time. When the laptop is not in use, such as at bedtime, plug it into an outlet and leave it to charge until the battery power is full.
7.Defrag regularly - The faster your hard drive does its work - less demand you are going to put on the hard drive and your ACER AP18K4K battery. Make your hard drive as efficient as possible by defragging it regularly.
