I'm looking for some help finding a replacement battery for my HP ZBook 15u G4. I’ve had a bit of trouble locating the correct part number or a reliable place to purchase one.
I’m based in Johannesburg, South Africa, so I’d appreciate any advice on where to find a compatible battery locally or through an HP-authorised reseller. Also, if anyone knows whether HP still provides direct support or installation services for this model in my region, that would be great to know too.
Thanks in advance for any guidance!

Welcome to our HP Community forum!
The part number for a battery for your HP ZBook 15u G4 Mobile Workstation is: 854108-850 "Battery pack (Primary) - 3-cell lithium-Ion (Li-Ion), 4.42Ah, 51Wh (TA03XL-PL)".
You can purchase a quality TA03XL replacement battery online, such as via Amazon-ZA: https://www.amazon.co.za/Reliable-long-lasting-Vibrant-EliteBook-755/dp/B0DY7PMFHD/ref=sr_1_4?crid=2....
It does not appear that you can buy this battery directly via HP anymore.

Btw, I couldn't locate the specific HP instructional video for your HP ZBook, but only for the "HP ZBook Studio G5 and ZBook 15 G4 Mobile Workstations".
Starting with: "Remove the Base Enclosure": https://www.youtube.com/watch?v=86_1Ka7N2T0, followed by: "Replace the Battery": https://www.youtube.com/watch?v=gfcIEkqYLNQ.
In any regards, replacing the battery of a ZBook is not as straightforward or easy compared with other laptops, so you may want to look for a local PC/Laptop Service business if you are not comfortable replacing the battery yourself.
