Direct replacement battery

This lithium-ion battery replaces the original pack in BOSE S1 Pro, S1 Pro Multi-Position PA System and S1 Pro System speakers. It matches the 14.4 V nominal voltage and 5400 mAh capacity so the speaker recognises the pack without modification. The decoded chip reports charge status exactly as the factory unit does. Dimensions are 148.00 x 98.74 x 36.44 mm and weight is 551.6 g.

Sustained discharge behaviour

The 77.76 Wh rating supports extended playback at moderate volume before the protection circuit intervenes. Over-charge, over-discharge, over-voltage and short-circuit safeguards prevent cell damage during long sessions. After two or three full charge cycles the pack reaches its rated runtime. Avoid chargers that do not meet the original specification to maintain cycle life.

Capacity decides fit

The single figure that confirms compatibility is the 5400 mAh capacity at 14.4 V. If your original battery shows a different milliamp-hour rating or voltage this pack will not be the correct replacement. Verify the part numbers 078592, 789175 or 789175-0010 on the old battery before ordering.

Questions about this item

Does the 14.4 V lithium-ion pack run warm or draw extra power during all-day use?

The replacement matches the original 14.4 V 5400 mAh specification, so heat and current draw stay the same as the factory battery.

What must I already own to install this 148.00 x 98.74 x 36.44 mm pack in my BOSE S1 Pro?

You need the speaker itself and basic tools to open the battery compartment; the pack includes a pre-fitted connector that plugs straight in.

Will this 5400 mAh cell work alongside the original charger and firmware on an older S1 Pro unit?

Yes, the fully decoded chip communicates identically to the OEM battery, so the existing charger and speaker firmware recognise it without updates.
