Battery replacement for Anker SoundCore Boost

This 2600 mAh 7.4 V lithium-ion pack replaces the original 2S18650 battery inside the Anker SoundCore Boost A3145 speaker. It restores the 19.24 Wh capacity the speaker was designed for. Installation tools are included in the package.

For owners needing a direct cell swap

The pack fits only the Anker SoundCore Boost A3145 model and matches the factory voltage and connector layout. Buyers who want more storage or a different voltage should look at something else because this replacement does not alter the speaker's power specification.

7.4 V 2600 mAh 2S18650 lithium-ion pack

The single specification that decides compatibility is the 7.4 V 2600 mAh 2S18650 lithium-ion pack. If the speaker requires this exact voltage, capacity and cell arrangement the battery will work; otherwise it will not.
