I have uploaded photo descriptions of the process. Use a 7/64” hex bit to remove the back panel of your Block Rocker Plus (BRP) and follow the steps. The battery came fully charged. The price is worth it for the $$ I paid for the BRP. Considering you have all the tools it was an easy installation. The fit works well in the BRP, and this is quality battery I could find.

We almost wasted money on a brand-new block rocker. The battery stopped holding a charge. Good old YouTube saved us. The old battery is easy to take out and replace. Now our two-year-old Block Rocker works great and holds a charge.

My 16 yo son burned the battery in our block rocker by leaving it in the car all summer long (apparently the car radio wasn’t loud enough.)This fit perfectly and now our block rocker works like new.

Years back I ordered the block rocker plus Bluetooth speaker which I love. Recently it stopped charging. I thought I would have to buy a whole new speaker until I did a quick specs check on Amazon and discovered that it has a replacement battery. Though it was not a prime product I received it in a couple of days and had music flowing throughout my home in 48 hours! So instead of spending another $200+ dollars I only spent $30. What a cost saving deal!
