How to open Dell battery

Take apart Dell laptop battery



Here’s how I was able to open the battery from my Dell. I had to take it apart because the locking mechanism 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 it had two small latches close to the connector. One latch on the right side.

Release latch

The second latch on the left side.

Unlock second latch

You can unlock latches with a small flathead screwdriver and insert something (I’m using a guitar pick) between the connector and cover to keep them separated.

Split the battery case

At the same time insert another guitar pick between the covers on the side and move it along the side unlocking hidden latches inside.

Separate top and bottom parts

Do the same with the other side.

Continue separating battery case

Keep working with the guitar pick until both covers are separated.

Open the battery case

Now you can remove the cover.

Remove battery cover

The battery has been disassembled. After that I opened the second (dead) one and transferred the locking mechanism to the working battery.

  1. I have tried but my battery did was glued together – not that simple as using a guitar pick.
    I did destroyed mine in the process

    It’s not easy. If you’ve never done it before you can and most likely will destroy the battery.
    I’m just showing that it’s possible.

  3. LOL just buy a new battery, they’re pretty cheap aftermarket, try FastBatts

    I’m not saying that you must fix the battery yourself. I’m just explaining how i did it.

  10. 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.

  11. 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.

    It is highly useful for me. Massive thumbs up for this blog post!

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

    Thank you,
    Andrew

  14. 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.

  15. that’s Dell latitude d610 battery
