Questions about this item

How often will the 150mAh 4.8V siren alarm battery need replacement?

The 150mAh capacity and 0.72Wh rating power the Mercedes-Benz CLK 270 or CLK 320 siren alarm; typical service life matches the original battery cycle count under normal vehicle use.

What limits continuous operation of the 24.50 x 26.50 x 14.50mm battery pack?

The 150mAh capacity is the first limit during sustained alarm activation; once the 0.72Wh reserve is depleted the siren stops until the vehicle charging system restores the 4.8V pack.

Does the 23.0g replacement battery generate noticeable heat or noise during daily operation?

The sealed 4.8V chemistry produces no audible noise and negligible heat while the vehicle is parked; the protection circuit prevents over-voltage stress during charging cycles.
