small for Behringer MPA40BT or PRO
Bought the MPA40BT-PRO less than 2.5 years ago with light to moderate use. The PA unit is good for outdoor performance (violin and cello duo), but the battery won't charge anymore after 2 years of moderate use. Since we registered the unit right after the purchase, so we tried Behringer 3-year warranty, but Behringer website claims it is out of warranty even it is not. Again Sweetwater shines on providing top level customer service - our service manager Chris worked with Skyler at tech dept to send us the BAT1 (the only battery available at Sweetwater for Behringer PA systems) in 2-day Fedex to help us out on a pending gig. The battery is for EPA40 and it is small in both physical size and amp (2.6AH) for MPA40BT (original battery is 5AH). So it works but won't last long. We ended up ordered an ExpertPower 12V 5AH battery with express shipping, and ExpertPower worked well for the gig, but we will have to see if it lasts long.
