Here’s how I was able to open the battery from my Dell laptop. I had to take it apart because the locking mechanism on the battery was broken. I decided to fix it by using the locking mechanism from another similar dead Dell battery.
I wasn’t sure if I can open the battery because it looked sealed.
To my surprise, it wasn’t difficult but you have to be very careful. If something goes wrong you can (and most likely will) destroy the battery or will not be able to assemble it back together. Proceed on your own risk.
I found that my battery had two small latches close to the connector. One latch on the right side.
The second latch on the left side.
You can unlock latches with a small flathead screwdriver and insert something (I’m using a guitar pick) between the battery connector and cover to keep them separated.
At the same time insert another guitar pick between the battery covers on the side and move it along the side unlocking hidden latches inside.
Do the same with the second side of the battery.
Keep working with the guitar pick until both covers are separated.
Now you can remove the cover.
The battery has been disassembled. After that I opened the second (dead) battery and transferred the locking mechanism to the working battery.

Works for me.
I was able to open the pack in 5 min and no damage.
Fitted 6 new 18650 Li batteries with 3.8Ah (instead of existing 2.35Ah) for 9$. another 2 hours work.
I could forgive Dell for the poor battery pack engineering if they charged less for replacement batteries.

Could you please share with us what model of Dell battery this is (and for which computer model)?
Thank you,
Andrew

Glad for the information – I have a different method in mind to open the battery pack; I will either use a soldering iron to burn off the area where the little tabs are on each side of the connector
or use a sharp utility knife to cut that area off. After making repairs to the battery pack, I will possibly then use super glue to glue the pack back together. The pack that I am working on will not take a charge – I intend to “zap” each cell with low voltage/low current to see if a bad cell can be revitalized. Don’t laugh – it does work – one bad cell can trash an entire pack, and this might give a bad pack a bit more life.

Thanks for the instructions. I opened up my Type Y4367 with relative ease. I don’t think I would have attempted without your pics. Mine looked just like yours except with 9 green cells instead of 6.
