Compatible replacement battery

This Cameron Sino lithium-ion pack replaces the original J406/ICR18650NH-2S cell in Bang & Olufsen BeoLit 15, BeoLit 17, BeoPlay A2 and BeoPlay A2 Active speakers. It is built to the same 7.4 V specification and 3400 mAh capacity, with a fully decoded chip that communicates with the speaker electronics. The pack measures 132.05 x 22.20 x 18.50 mm and weighs 97.3 g.

Runtime and limits

A 3400 mAh / 25.16 Wh rating restores the factory playtime for the listed models, so typical listening sessions run as long as they did when the speaker was new. Capacity will fall short for owners who need multi-day operation away from a charger or who run the speaker continuously at maximum volume. The pack is not a high-capacity upgrade and cannot extend runtime beyond the original design.

Decisive specification

The 7.4 V nominal voltage and the exact J406/ICR18650NH-2S part number decide fit; a different voltage or connector will not work in these speakers. Buyers must verify the original battery carries this part number before ordering, as other Bang & Olufsen models use incompatible packs.

Questions about this item

Will the 132.05 x 22.20 x 18.50 mm pack sit flush in the BeoPlay A2 Active compartment without forcing the latch?

The pack matches the original J406 dimensions exactly, so it seats the same way and the latch closes normally.

How can I confirm the 7.4 V 3400 mAh pack is delivering full capacity after the first few charge cycles?

Run two or three full charge and discharge cycles; the decoded chip then reports true capacity to the speaker’s fuel gauge.

Does the box include a screwdriver or opening tool for the BeoLit 15 battery swap?

Only the battery with its pre-fitted connector and protective foam are supplied; tools must be sourced separately.
