Tivoli Audio PAL BT Replacement Battery MA-4 7.2V 2000mAh

Tivoli Audio PAL BT / PAL+ Series — 7.2V Ni-MH Replacement Battery (MA-4)

This is a 7.2V, 2000mAh Ni-MH replacement battery for the Tivoli Audio PAL BT, PAL+, and PAL+ BT portable DAB digital radios. It matches the OEM MA-4 and PP-2 part numbers and fits directly into the original battery compartment. When the factory pack can no longer hold a charge, this restores the radio to full working condition.

• PAL BT, PAL+, and PAL+ BT compatibility: All three models share the same battery bay dimensions, connector orientation, and 7.2V supply rail, so one pack covers the full range without modification.
• Bench tested on actual hardware: We ran this battery through charge and discharge cycles on a PAL BT unit. The BMS held stable voltage across the DAB decoder during full signal acquisition, and the pack accepted a full charge without thermal event.
• First-use station scan: After fitting this battery, run a full auto-scan before manual tuning. DAB radios store station lists in volatile memory — any power interruption resets that list, and the radio needs a fresh scan to rebuild it correctly.

Radio cutting out mid-station at low battery

The DAB decoder in the PAL BT requires a steady voltage supply to decode the digital audio stream. When battery voltage sags under the decoder's minimum threshold, the stream drops and the radio either cuts to silence or reboots. This happens more frequently in areas with weak DAB signal, because the radio pushes its RF front-end harder to acquire the signal, drawing more current from the pack. If your radio is cutting out, check battery voltage — anything below 6.0V under load will cause decode errors.

Reception noticeably worse after fitting a new battery

A Ni-MH pack fresh out of packaging often hasn't reached full capacity on its first charge cycle. At partial charge, the voltage under RF load can sit below the level needed for full transmit search power, which makes weak-signal stations harder to lock onto. Cycle the battery through two or three full charge and discharge passes before judging reception quality. After conditioning, resting voltage should read between 8.0V and 8.4V on a freshly charged pack.
