Hi Larry, I've been looking for ages for a battery that will adequately replace the one in the JBL Charge! After some research, I discovered the battery model is AEC982999-2P, which is a 3.7V 6000mAh battery. A quick Google search did not return a replacement that is the same size as the JBL Charge's. I know it's not a very common site to use in the US, but Alibaba.com is a good place to look! Hope this helps! Thanks Joe
Hi Olivier, I personally wouldn't do that on my device, as JBL probably picked their fabric to ensure dust protection along with quality sound. On the other hand, depending on the environment it is used in, removing the covers shouldn't necessarily ruin the device. I say go for it!
I'd be interested to know what your results were, if you decided to remove the fabric?
