• It can compatible the battery model of my ACER 4UR18650F-2-QC218 original battery.
• It is show clearly this battery can fit my machine model.(Not Necessary).

Other usefull knowledge for find a correct laptop battery.

• Battery OutPut Volt : 10.8v and 11.1v, 14.4v and 14.8v can compatible each other, beacuse all laptops can deal with as max as 0.8V voltage difference.
• Higher capacity means longer working time and use life, it is a good choosen.
• Try seach with the laptop model or battery number on our site, you can find correct item easliy.
• Tell us your laptop model and the battery number will help you get a correct item.

What can we do to extend a laptops battery life?

How often should I completely discharge my laptop battery?

Intentionally... never. Unless your battery management controllers are needing to be calibrated to the actual battery capacity there is no need to deplete the battery. Lithium ion batteries are happiest between 60% and 80%, fully charged or discharged batteries have high and low voltage stresses respectively. Fortunately it is supposed to be impossible to fully discharge a lithium ion battery, the battery management circuits typically cut you off to keep them above 3 volts per cell which is the danger zone. This is why a phone with a depleted battery can still power up and show a low battery icon, it's a safety net to avoid anyone blowing up their batteries, you get to see the 0% to 100% of the usable charge range of the batteries.

Coincidentally, ideal usage of lithium ion batteries isn't that different from normal laptop and phone usage, like I said the more time it spends in the 60% to 80% range the better as that's near the ideal charge voltage of this battery type and unless the user is like me they usually don't spend a ton of time fully charged unless they plug in over night.
