ِِMy laptop takes 19v /4.7 Am , does this battery can bear this amount of ampere

Current ratings are a funny thing.The 4.7A label on your laptop is "worst case" draw. If all you are doing is musing the Internet, watching cat videos, and working on Office documents, it'll be fine.However, if you go playing high end 3D games on your laptop with the battery charging while using this adapter, it may overload out and shut down.Just keep that in mind while using it.

This battery is rated at 4.5 amps according to the description. Generally, matching voltages is more important than matching amperages, but laptops chargers are pretty versatile. My laptop takes 19v/4.5a but it will charge with a 16v/3.5a, though more slowly. Your laptop would most likely work fine with this battery. I haven't seen any external batteries that offer 4.7 amps - 3, 3.5, and 4.5 amps appears to be standard.

Hello, I have a gamer type laptop, it requires high amperage. The charger gets very hot, and when my battery is low, during charging the screen flickers, not enough juice in the beginning. But it does work, hope this helps

This battery is by the numbers is .1ah larger than what you have, which simply means more run capacity. The voltage is the same so it should not be a problem.

It works fine charging and maintaining my 105 amp hour deep cycle trolling motor battery. With only 6 amps max charge rate, I believe that charging is easier (with less heat) on the almost 4 yr old battery, yet it is fully charged overnight.

It all depends on the charger you have. The voltage will be the same as a car battery but the amp hour rating will be much lower. Think of the amp rating as the amount of energy the battery will hold. Just check you charger for the amp ratings its capable of charging. If it will charge at something close to 2 amps, you should be okay. Hope this helps.

If I remember correctly, this is a 100 amp/hr battery. I use 2 of them in my solar setup, they are solid and dependable.

It is a 18 Volt NiCd battery, and ranks above average for capacity and run time, the average capacity for this class is 2.2 AH, so I would think it is slightly higher... Mine works outstanding ! Hope this helps ...

you need 18.5 V dc @ 3.5A - 65 W or 19.5V dc @ 3.33 A - 65 W to power your Ultrabook.

This is a 6 cell battery with 1500mamphr of power. My laptop is used as a desk top so I don't stress battery as it is normally plugged in. However when old battery failed I had to remove it to avoid error msgs. This was very low priced solution for my needs.

I wish I could answer that for you. I am not sure. It would be best if there was a cross reference chart for your Laptop battery to find out for sure. Sorry I am not of help for you. Steve

The amperage is too high on the charger for this battery. I would recommend you to use a 2 Amp charger.

Yes. It has a universal switching power supply, 19v output. Same as many current laptops.
