About this replacement
Grace Mondo GDI-IRC6000 Series — 7.4V Li-ion Replacement Battery (ACC-IRCLI)
This 7.4V, 6800mAh Li-ion battery replaces the OEM ACC-IRCLI pack in the Grace Mondo GDI-IRC6000, GDI-IRC6000R, and GDI-IRC6000W portable DAB digital radios. It restores full wireless operation to your digital receiver without modification. Capacity figures are taken directly from the product specification — 50.32Wh total energy storage.
- GDI-IRC6000 series compatibility: The GDI-IRC6000, GDI-IRC6000R, and GDI-IRC6000W all share the same battery bay geometry, connector pinout, and 7.4V supply rail. The BMS communication protocol is identical across all three variants, so one pack covers the entire colour range.
- Bench tested on actual hardware: We ran the ACC-IRCLI replacement through full charge and discharge cycles on a GDI-IRC6000 unit. The onboard BMS accepted the pack without error flags, and the battery indicator tracked correctly through all charge states.
- First-use station scan: After fitting this battery, let the radio run a full auto-scan before manual tuning. DAB station lists are held in volatile memory and are lost when power is interrupted. A fresh scan rebuilds the complete station index for your region.
Radio cutting out mid-station at low battery
The DAB decoder in the GDI-IRC6000 needs a stable voltage to sustain the OFDM stream decode process. As the battery drops toward its low-voltage threshold, the supply rail sags under the RF and decoder load. When voltage falls below roughly 6.6V under load, the decoder loses sync and the audio stream drops out — even if the battery indicator still shows one bar. The fix is to charge before that threshold, not when the radio goes silent.
Noticeably shorter use between charges in weak signal areas
In areas with poor DAB coverage, the GDI-IRC6000 increases its RF front-end search power to hold onto weak multiplex signals. This draws significantly more current from the battery than normal reception does. The result is noticeably reduced time between charges — this is normal behaviour, not a battery defect. Moving the radio closer to a window or an external aerial point reduces that extra RF draw and extends your charge cycle.
