Replacement Battery for Marshall Emberton Speakers

This Estry lithium battery replaces the original pack in Marshall Emberton 1005696 and Emberton II 1001908 portable speakers. It matches the factory form factor of 68.0 x 38.2 x 21.0 mm and weighs 127.0 g. The cell delivers 7.4 V and carries certifications including ISO9001, RoHS, CE, UN38.3 and MSDS. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Capacity and Runtime Headroom

The pack is rated at 3350 mAh and 24.79 Wh, compared with the 3000 mAh specification of the original battery. The higher capacity extends listening time between charges for typical indoor and outdoor use. Runtime will decrease at maximum volume levels or in very cold conditions where lithium chemistry loses efficiency. Heavy bass content also draws more current and reduces overall playtime.

Voltage and Compatibility Limits

The 7.4 V nominal voltage is fixed by the two-cell lithium configuration and must match the speaker's power input exactly. This battery fits only the Emberton models listed and the C406A2 or C406A2-2 part numbers; it will not work with other Marshall speakers or third-party devices. The protection circuit prevents unsafe operation but cannot compensate for an incorrect voltage requirement.

Questions about this item

Will the 68.0 x 38.2 x 21.0 mm battery fit inside my original Emberton 1005696 speaker without modification?

Yes, the replacement matches the factory dimensions of 68.0 x 38.2 x 21.0 mm and weighs 127.0 g, so it seats in the existing compartment exactly like the original cell.

How can I verify the 7.4 V 3350 mAh pack is charging and holding capacity after installation?

After a full charge the speaker should reach its rated playtime; you can also measure 7.4 V at the pack terminals with a multimeter to confirm the voltage is present.

Does the single 7.4 V 3350 mAh lithium pack come with any tools or adhesive strips, or must I supply them?

The box contains only the 1-pack battery itself; opening tools, pry picks and replacement adhesive are not included and must be sourced separately.
