About this replacement
Roberts Revival Icon / Stream 95i — 10.8V Li-ion Replacement Battery (BP18650-3S1P)
This 10.8V, 2600mAh lithium-ion battery replaces the original pack in the Roberts Revival Icon and Stream 95i portable DAB/FM radios. It slots into the same bay and connects to the same BMS interface as the factory unit. Capacity figure is taken directly from product data — 28.08Wh total energy.
- Revival Icon and Stream 95i compatibility: Both models share the same 10.8V three-cell Li-ion architecture and use the same BP18650-3S1P pack format. The battery management handshake and connector pinout are identical across this pair, so one replacement covers both.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a Roberts DAB unit. The BMS accepted charge from the radio's internal charger without fault flags, and cell balancing across all three cells stayed within spec throughout.
- Post-installation scan tip: After fitting the new battery, let the radio run a full automatic DAB station scan before you tune manually. The station list sits in volatile memory and is wiped on power loss — a forced rescan rebuilds it cleanly rather than leaving gaps in the stored multiplex list.
DAB stream dropout at low battery on the Revival Icon
The Revival Icon's DAB decoder needs a stable voltage to reassemble the OFDM signal into audio. When cell voltage sags below the decoder's minimum threshold — typically around 9.6V at pack level on a depleted 10.8V three-cell pack — the chip starts dropping frames before the radio shows a low-battery warning. The audio cuts, stutters, or goes silent even though the radio appears to still be on. Fitting a fresh pack with full cell charge restores the voltage headroom the decoder needs to stay locked on the multiplex.
Battery draining faster than expected in weak signal areas
The Revival Icon increases RF search power when DAB signal strength is low, which pulls more current from the battery than normal listening does. In fringe-coverage locations the radio is effectively working harder to maintain lock on a multiplex, and that extra draw shortens use time noticeably. This is not a fault with the battery — it is the radio's normal behaviour. Moving the aerial to a window position or extending it fully reduces the load and brings draw back down to typical levels.
