Introduction

Ce dont vous avez besoin
-
-
Flip your speaker over and insert the plastic opening tool into the slit on the grille.
-
Pry away from yourself towards the back of the speaker to release the clip.
-
Repeat this process for the clip on the other side.
-
-
-
Remove the two 8mm Phillips #0 screws from the other edge of the grille.
You have to remove the 8 mm screws before you try and Prius the other side. They are attached, and will break
-
-
-
Using the plastic opening tool, lift the tab on top of the speaker to release the radiator from the clips.
-
Repeat this process on the other clips around the radiator to release it from the frame.
There is absolutely no reason to remove the passive radiators if you want to replace the speaker only!
Just cut to step 6.
Also the difficulty level is way too high. I found it very easy to disassemble the unit.
-
-
-
-
Remove the two 6mm Phillips #0 screws on the front side of the port bay cover.
-
-
-
Remove the sticky tape to expose the white ribbon cable ZIF connector.
-
Flip up the black locking flap on the ZIF connector with the tip of a spudger or your fingernail to release the cable.
-
Remove the white ribbon cable from the battery cover and place the cover to the side.
Don't remove this white ribbon cable from the circuit board, it's almost impossible to plug it back. Instead of removing the cable, just remove the circuit board which is glued loosely to the plate. If you can get to the battery itself, you don't have to remove the circuit board neither.
-
-
-
Pull out the battery enough to expose the battery's wire connector.
-
Push down on the white tab and gently pull out the battery-device connector.

Where do you buy a battery for a jbl Charge 4 ??
Probably just cut open the blue foil around the batteries and replace them by re-soldering the electronics onto new 18650 batteries.
correct me if I’m wrong here.
If you know how to handle them and have experience with soldering them that's a yes if not those batteries are really dangerous if you don't know how to do it correctly.

Where in the !&&* do i get a battery for a bluetooth speaker. What happened to the jbl charge 4 that it even goes out???
My JBL charge 4 battery dead too. 9nly uses it for three months
How is the battery 6 pins? Any idea what the middle 2 wires do? The outer ones seems +and - 3.7v if the cells are in parallel. Can anyone shine a light on the configuration/wiring of the cells?
Middle connections are scl sda serial connections. For communication from battery board to main board.

Does the battery come charged already?
After replacement mine turns on and right off again any ideas
Did you ever solve this? Thinking of replacing a battery in my 4, but saw a few Reddit posts saying they had similar issues- new battery didn’t allow power up. One person put their original battery back in, and speaker worked, but old battery only.
I’m in the same boat. Replaced battery and speaker turns on then off. Doesn’t seem to be taking a charge.
You have to be an expert electronics technician to replace a battery! My JBL Charge 4 lasted one (1) battery charge cycle! Now I gotta go back to vocational school for a year to be able to listen to it for what, one more charge cycle???? Besides that Walmart won't exchange it because it was the 92nd day from the purchase date. WHAT A FREAKING JOKE!
I think there are just 3 18350 2600mah cells in parallel, I would just keep the genuine BMS and only raplace the cells. Good soldering iron and some serious skills are required.
My jbl charge 4 has heat problems and doesn't charge. The port and plug in the usb c get very hot and no charge what so ever. Will replacing the battery solve this issue. Plz help.
ich schaffe es nur auf der einen seite. Auf der anderen ist die abdeckung viel zu fest dran ? was kann ich machen ?
