No, you only have to disconnect the right passive radiator to get to the battery and plug it.

You can purchase the JBL charge 2 "plus" battery on eBay. See my post below for details on modifications that are required.

Great guide but where to source a battery for a JBL charge 2.

Mine failed, complained to Harman and they sent a new one and didn't want the old one so have a spare I'd like to get working.

Thanks in advance

Had my speaker for a month. It won't charge. Why did it only last a month and I have to get a new one? I'm not satisfied with the speaker for the price that I paid.

Try disconnecting the battery and plugging it in again.

I just had the same problem, the on/off led got stuck and couldn't get any sound or operation from any button. After different attempts a simultaneous pressing of the Phone together with the - and the + button brought my Charge2 to life again.

Hi Dave, the link to the battery you posted does not connect to the Charge 2 Plus. If you notice in the pictures, there are 5 different cords connecting the battery to the device (they are red white and black in the pictures). However the battery in your link only has 3 different cords, and does not connect correctly with Charge 2 Plus (I ordered this battery and tried to install it and it does not connect as it requires a 5 cord connection). I searched everywhere and was unable to find a replacement battery with a 5 cord connection for under $99, and a new Charge 2 plus costs less than that. This article has great instructions on how to replace the battery, but its currently cheaper to buy a new one rather than replace the battery unfortunately. Here is a link to the correct 5 cord replacement battery, hopefully the price on these will eventually go down: http://www.ebay.com/itm/Original-JBL-Cha...

Hi!

My guess is that you can chopp of the 5 wire connection and simply resolder it to the new battery.

Since in the picture there are two red wires and two black, my guess is that it is for spreading out the current that is drawn over multiple wires.

It could also be that it is used for charging the battery but it shouldn't matter if you solder both the red ones to the only red on the new battery and also for the black wires.

I have not disassembled the charge 2 myself but I have some experience with the batterys. but does what I say make sense?

Kim A -

Sry, had to make an additional comment. I realized that I actually is a bit confused over the 3 wires from the 3.7V battery. Usually they are at 7.4 V when they have 3 wires going from the battery. So I might have missed something here.

Kim A -

It appears that the white wire probably is for some kind of monitoring of the battery. So my first thoughts should still be valid according to me. But it is always a good thing to measure everything so you dont end up frying everything.

I searched everywhere for a solution to this and finally found a company who offer a replacement battery for the JBL Charge 2. Ordered one last week am just waiting to receive the product and will follow up once installed. The image shown for the battery has the exact amount of wires of my original, here is the link https://www.canadianbatteries.com/batter...

Dan,

Please see my post below. The battery you ordered will work, but the positive and negative wires must be flipped.

Hi,

For everyone looking for a JBL charge 2 plus battery replacement (5 wire) you can buy the Carmen Sino battery on eBay.

Search for MLP12995-2P

However, these batteries (including battery link in Dan Clark's posting) have the positive and negative wires backwards and require you flip them. The male plastic clip on the end of the battery only installs one way into the JBL circuit board female connector and the way the battery arrives is incorrect.

Good luck!

PS - I do not sell these on eBay. I just had to find out the hard way and wanted to share my fix.

Craig D - Reply

is it hard to flip the wires? special tools needed? Do I need to buy a new male connector to make the flip?

Crimson Castillo -

i had the same problem, so i used the easiest way, i used bare power ;-) just press the male connector in different direction to the female connector. the plastic isn't really strong and it's directly working. problem is when you build the battery back to it's plastic case and back to the charge body, the cable slips out bcs it's too short and less space. so i used another easy way: the hot-glue-pistole to attach the connector. everything working very well now!

JBL Charge 2 plus battery replacement only requires the rear grill to be removed. Once removed there is 5 little screws that hold the battery pack in place and 1 additional screw that holds the battery in the case.

You do not need to remove the front grill or subs to access the bettery.

Thank you. Your steps worked perfectly. I just wanted to remove my battery connection to reset my jbl charge 2 as buttons were not working for reset. Followed your steps and it worked. By the way the battery connection is on the subwoofer which is close to power button. You need to just open that woofer if you want to reset like me.
