Universal Battery vs. Original Battery
Hy S Gresham,
Actually you may use universal battery for your laptop too if that will be a well known brand or high quality product. You may use 8000- 20000 mAh Universal External battery for your laptop. An universal battery can also give extend battery life almost 4hrs – 8 hrs. So just choose a well known brand for use as your laptop battery.
You should remember that, never leave your laptop battery in direct sunlight. It will damage your battery. And you should put your battery in cool place. All kinds of battery should fully discharge and then charge again for future use.
Finally I can say Universal battery is almost effective as like as normal battery in laptop.
