This replacement battery V104 Battery for HP Probook 450 fits perfectly on my HP Probook and the battery seems to hold its charge nicely. I think it is good deal considering the price. I cannot say about the longevity as I have been only using it for past week or so but, I am consistently getting 3-4 hours of use which is about the same I used to get from the original battery from HP which gives me confidence that will last just as long as the original.PS: You can run this command using an "elevated command prompt" AKA run as administrator to get the battery details:c:\> powercfg /energyThe above command under Windows 10, will generate a HTML report of the system and that report will have the information of the battery and let you know the charge capacity and charge details. If the charge capacity (After a full charge) nears the advertised values then your battery is in good condition. Please see the pictures that I have posted along with this review to get an idea what you are purchasing. If things were to deteriorate after few months, I will come back and revise my review.Thanks for reading my review. Cheers! Happy Shopping!

This is a revision to my original review after a reasonable amount of time has elapsed.I bought this battery on April 11, 2020. By October, 2020 (shortly after any support expired) the battery's ability to hold a full charge began to diminish. By December, 2020 this battery would no hold a charge at all. It is completely dead. It was the lowest priced battery on Amazon and now I know why.I repeat: DO NOT BUY.

Bought it for my laptop and it worked great for about 5 1/2 months. Now my laptop is telling me my battery is defective and won't take a charge. Waste of money for me. Beware.

I was hesitant, but decided for $20 I would take a chance. Our previous OEM battery wasn't charging past 73% and discharged within 20 minutes. This battery takes a full charge, and last the same as the battery that came with the laptop.

I guess you can expect that from a battery that costs 20 bucks. It's like a spare tire for your laptop, it may charge up all the way but it unfortunately drains quickly. It can go maybe up to an hour without having to charge your laptop. You may as well upgrade your laptop or simply save up a lot of money for a really good battery.

Item was just how it was described. Very happy with experience with this seller, highly recommend them.

I use this battery in my HP Envy and can't get more than about 40 minutes out of a charge. Perhaps that's all I should expect; I don't know. But I do know it is unacceptable to me.

Battery was un-recognized by computer... simply would not see that it was there, hence "No Battery".Returned for refund, without issue.

Easy to install. Great price.
