Replacement battery for Volvo alarm siren

This nickel-zinc battery replaces the original alarm siren cell in Volvo S60, S80, XC60, V60, V70 and XC70 models produced between 2008 and 2018. It matches part numbers 30659412, 30659883 and 55AAAH2BMX. The pack weighs 51 g and measures 45.50 x 21.10 x 10.80 mm. A fully decoded chip ensures the siren recognises the battery immediately.

Thermals noise and power draw

Rated at 2.4 V with a capacity of 700 mAh, the cell stores 1.68 Wh of energy for standby security duty. Nickel-zinc chemistry delivers stable voltage during long periods of inactivity and tolerates the temperature range found in engine-bay locations. No fan or active cooling is involved, so operation is silent and power draw is limited to the siren's own monitoring circuit.

Capacity decides fit

The 700 mAh capacity is the single figure that determines whether this unit will sustain the alarm through its designed standby period. Buyers needing a higher ampere-hour rating for extended backup or for a different vehicle platform should look elsewhere. Verify the original part number before purchase to confirm compatibility.

Questions about this item

How do I install the 700mAh 2.4V battery in the VOLVO FOMOCO alarm siren and which step is often missed?

Open the siren housing, unplug the original pack, connect the new battery's connector firmly until it clicks, then reseal the unit; the step most often missed is verifying the connector is fully seated before closing the case.

What maintenance or replacement will this Nickel-Zinc 700mAh cell need later?

The battery is maintenance-free; after 2–3 full charge and discharge cycles it reaches peak capacity, and it will eventually require replacement when it no longer holds enough charge to power the siren.

What limit appears first during sustained use of the 1.68Wh siren battery?

The protection circuit stops output if the cell is over-discharged, over-charged, or short-circuited, and the pack must not be stored above 60°C (140°F) or the internal safeguards will prevent further operation.
