What battery is required?

You’ve got to be joking - so you spend £100 on a speaker and then need a degree in electrical engineering to replace the battery - what a load of s***e

exactly, I agree

I replaced the battery in mine. It took about an hour and it was easy, while the instructions appear complicated, undoing a few screws and folding back some tabs took only a few seconds. Before I replaced the battery my Boom had failed completely. Nothing I tried kicked the dead battery into working again, so I had two choices. Try replacing the battery or chucking it in the bin. So I bought a battery and had a go. I read up and had the right tools, and as luck favours the prepared, I was successful. The only warning I can think of is that out of the box the Boom is water resistant I believe, but post repair, I doubt it’s water resistant now.

Don’t pry open the entire thing. Open the side with the d-ring, there should be 4 screws like in the pic above and access to battery directly under that. There’s instructions for changing battery in the box.
