4430s Laptop Battery Replacement Fit for HP Probook 4540s 4440s 4530s 4535s 4545s 4431s 4435s 4330s Series, fits Laptop Part Number 633805-001 PR06 PR09 HSTNN-IB2R 633733-321 11.1V 5200mAh

Easy to install and now my laptop is finally working again.

So far so good. Needed a replacement battery to sell a laptop and it held charge well.

Easy install, no issues. Battery life isn’t great (1-2 hours) but is a lot better than the original 6 year old manufacturer battery.

Fit perfectly in my laptop and the life is good, not great, but it’s an older laptop that I keep in the garage for when I need it.

It was OK at first, but weakened and then finally died only 12 days after the end of the return window.

Installation went great. Easy to get in laptop. The only complaint is that I now get a massage every time I startup the laptop warning me that it's not HP OEM

I just started using it, so far seems to hold charge. But the sizing was weird. I could only fit the battery if I pressed really hard on the back part of it. It looks just like the original but somehow it fails to fit correctly. Either you slide from the back or the front, one side needs to be pressed. I recommend pressing from the back and not the pin connector so as not to damage the charging socket.I will update my review with pictures once I get to see how much charge and for how long does it hold it.

I bought it On 21 July/20 and ii Arrived on 23 July/20. Very Pleased with delivery. Read the instruction, Replaced my original HP Probook 4540S with it, Perfect Fit (even Colour matches). Analysed and Tested with BIOS Diagnostic! Discharged to 1% capacity and Fully Charged it without PC ON and without any peripheral and LAN Cable. Turned on PC Analysed and Tested Again with BIOS. Used it without AC Power to Drain the Battery Again! This time instead of 2% capacity I accidentally Drained to 0%. Fully Charged Again and Started using It without any Problem.IT LOOKS LIKE IT IS GOOD REPLACEMENT OF HP 633805-001 BATTERY. MORE OVER SPECIFICATION MATCHES.Here iS THE INFORMATION OBTAINED FROM BIOS:Device Name: PRO6047Manufacturer: 13-15 (Instead Of Company Name!)S/N: 01526 (24/12/2018).
