Excellent
Mighty Max Battery
Based on 4334 reviews
The Monster Rockin' Roller OEM has foam tape to prevent the battery from shifting in the compartment. The Mighty Max does not. So, I'm improvising with parts of the corrugated container of the Mighty Max replacement battery Model: ML9-12.
I have installed it and it is charging. I'm excited to get my blue tooth boom box back!
I'm confident it will work at least for a year.
I could add a few more photos.
Pictures and videos really help me!
Feel free to send me what you got!
Arrived very well protected by package
