    Perfect. Plug & Play.

    If you are replacing the battery on a Boom yourself for the first time, you should first watch a few videos on youtube. The whole thing is not a big deal in itself, but a bit of manual care is required. Important: As the underbody is not simply plugged in, but also glued, a little patience is required. In addition, the boom base is connected to the appliance with a multiple plug. No loose cables. Take your time to work carefully - it's worth it.

    The plug connection of the battery to the boom is snapped into the holder on the device side and must therefore be lightly clamped at the top with (round-nose) pliers and then pulled out. Simply look at the plug of the replacement battery. The original battery has some adhesive foam strips attached to it. They can be easily removed and reused to optimise the battery holder. PS. The plug connection of the battery is reverse polarity protected - so you can't plug anything in the wrong way round.
