Dell Studio N856P & U164P Battery Care and Use
You can extend the life of your laptop battery significantly through the proper care and handling of your battery.
- After installing your new laptop battery, fully charged your laptop overnight. To get the full charging capacity, you may need to calibrate your battery by fully charging it and then discharging it.
- Don't run your laptop all the way to 0% as it can damage the lithium-ion cells. It's best to starting recharging your battery before it gets to 20% (this is also true with your phone).
