Great product, works !
Fit perfectly and was charged. I hadn't used my laptop in 3 years and it cut on soon as I connects the battery and it came with slight charge I used it for two hours before needing to charge

Black screen surface pro4 due to batteries built wrong
My surface pro 4 was overheating and screen flickering. Internet says the battery is overheating, common issue. I purchased this battery, installed and was left with a tablet with a black screen. Ran a cord to a display and the tablet is working. Due to the screen being held with adhesive I thought I damaged the ribbon wire while removing the screen. I’ve since replaced the screen twice, the small display circuit board twice, and all ribbon wires twice. The screen will not work. I’ve redone the battery install, everything is correct. More online searching shows these off brand batteries have an incorrect circuit board. I’m well past my return window and I’ve discarded the original battery so I’m unable to transfer over the circuit board but I’ve bought a used original battery from a broken tablet and the tablet works. I see several comments stating they replaced the battery and believe the new ruined the circuitry leaving them with a useless tablet. It’s the circuitry within the battery that’s bad, not your tablet.

Laptop battery review
Good replacement for the battery that I needed to replace fits good charged up good I cycle the battery by charging it three times and then letting it go dead three times that's what you should do to cycle the battery so it takes full charge in the future and it will make the battery last a lot longer also when your battery is fully charged make sure you do not use the charger because it's removable battery if you're going to use the AC adapter just take the battery out because once the battery is charged it starts to discharge so it creates heat and if you have the charger on at the same time that creates another heat that's what kills better so just remember when you're using battery use battery when you're using the laptop at home and you on a AC the charger make sure you take the battery that's fully charged out that way you don't kill the battery
