Laptop Battery for HP 640, 5200mAh ( Hi-Quality Replacement Battery for HP 640 )

 
Microsoft says the LTE Pro lasts 12.5 hours between charges (compared to 13.5 for the Wi-Fi model), but that’s based on a looping video test and not real-world usage. In my experience, battery life on LTE has been closer to seven hours, which is a little less than I saw with the Wi-Fi version, but still in the acceptable range for this size computer. I’d have really loved to see Microsoft stick an even larger battery in this version to really make it a truly mobile computer, but I think most people will be satisfied with the LTE Pro’s battery life. The differences between using a computer that relies on a Wi-Fi network for internet and one that always just has a connection available are small, but they add up. Instead of having to set up a hot spot on my phone before opening my computer on the train and then waiting for the computer to find the hot spot and connect to it, I was able to just turn on the LTE Pro and get to work. As the train moved and the cellular connection went in and out (I tested it with T-Mobile service, but this applies to any carrier), the LTE Pro was able to find the network and reconnect faster after losing service than when I had to rely on my phone’s hot spot connection. On top of that, I don’t have to worry about draining both my phone’s battery and my laptop’s battery at the same time just to connect to the internet.

Using a cellular-connected computer is also more secure than relying on public Wi-Fi networks, and it’s more convenient than using a hot spot that requires an account and login, such as those provided by Boingo.Getting online with the LTE Surface Pro is so easy that I never had to think about it. It’s a computer that gets out of my way and just lets me do the things I need to get done, instead of distracting me with network settings or other annoyances. This is the reason I’ve long preferred a cellular-connected iPad over a Wi-Fi-only model, but here it’s extended to a full-fledged work computer.

Using a computer with a built-in cellular connection is so convenient that now I want every computer to have it. (It’s also something I’ve explicitly asked Microsoft for in the past.) It foreshadows a time when we won’t have to worry about whether or not the coffee shop we want to work from has Wi-Fi or if we’ll be able to take care of those emails while traveling. That future isn’t far off, and in the case of the Surface Pro LTE, it’s here now.ZDNet's Business Bargain Hunter scours the web for great deals on computers, phones, services and much more.

Probably not.That's too bad, because it sucks when your laptop battery gives out and you've still got work to do.
