Questions about this item

How long will the 2600mAh capacity last during continuous playback on the SoundLink Micro 423816?

The 2600mAh lithium pack stores 9.62Wh at 3.7V, matching the original specification for the SoundLink Micro 423816 so runtime equals the factory battery when new.

Does the battery run hot or make noise during all-day use inside the speaker?

The replacement cell uses the same lithium chemistry and 3.7V rating as the original, with overcharge, over-discharge and short-circuit protection, so thermal and acoustic behaviour is identical to the stock battery.

What tools or parts are needed to install this battery in a SoundLink Micro 423816?

The pack measures 65.8 x 20.64 x 18.42mm and weighs 115.4g, fitting the factory compartment; only a small Phillips screwdriver and plastic pry tool are typically required to open the speaker.
