Direct Replacement for Marshall Kilburn

This Estry battery pack is built to match the original specifications for the Marshall Kilburn speaker. It uses a lithium chemistry cell rated at 2600mAh and 14.4V, delivering 37.44Wh of energy. The unit is designed as a one-for-one swap for the TF18650-2200-1S4PA part number.

Protection Circuit Maintains Output Under Load

Integrated safeguards guard against overcharge, over-discharge, over-voltage and short-circuit events during extended playback sessions. These protections help the pack sustain its rated voltage without triggering premature shutdown when the speaker draws peak current. The cells are tested to hold specification through repeated charge cycles.

Simple Swap With Verified Fit

The pack measures 73.7 x 69.16 x 19.3mm and weighs 270.0g, matching the factory footprint so no modification to the speaker chassis is required. Installation consists of opening the battery compartment, disconnecting the old pack and connecting the new one. Buyers who need a different voltage or capacity will not be served by this model.

Questions about this item

Does the 14.4 V 2600 mAh pack generate noticeable heat or noise during extended playback?

The lithium pack has no moving parts and includes over-voltage, over-discharge and short-circuit protection, so it runs silently and stays at normal operating temperature during all-day use.

What must I already own for this replacement to work in my speaker?

You need a Marshall Kilburn portable speaker that originally used the TF18650-2200-1S4PA battery module.

Will the 73.7 x 69.16 x 19.3 mm dimensions fit the original Kilburn battery compartment without modification?

Yes, the pack is built to the exact specifications of the original TF18650-2200-1S4PA module, so it slots into the existing compartment with no alterations required.
