Replacement Battery for Sony Speakers

This Estry lithium battery replaces the original pack in Sony SRS-XB30, SRS-X30, SRS-XB43 and SRS-XB3 portable speakers. It delivers a nominal 7.4 V and a rated capacity of 5200 mAh for 38.48 Wh of energy. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection circuits. It is supplied new and certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Who This Suits and Who Should Look Elsewhere

Owners of the listed Sony models who need a direct-fit replacement with the same voltage and connector will find this pack matches the original ID659B, ID659 and ST-06S part numbers. The physical dimensions of 67.94 x 37.58 x 37.02 mm and weight of 260.4 g replicate the factory pack. Buyers with different speaker models or incompatible part numbers cannot use this battery.

Deciding Specification — Voltage and Capacity Match

The critical figure is the 7.4 V nominal voltage combined with the 5200 mAh capacity; both must match the original battery exactly for safe operation and correct runtime. A different voltage would damage the speaker electronics, while a lower capacity would reduce playtime. Confirm the model number and part number on your existing pack before ordering.

Questions about this item

Does the 7.4 V 5200 mAh pack run hot or draw extra power during all-day playback?

The lithium pack is rated at 38.48 Wh with built-in over-charge, over-discharge and short-circuit protection, so it maintains stable voltage without excess heat under normal speaker use.

What must I already own for this 67.94 × 37.58 × 37.02 mm battery to work?

You need one of the compatible Sony speakers — SRS-XB30, SRS-X30, SRS-XB43 or SRS-XB3 — or an original battery carrying part number ID659B, ID659 or ST-06S.

Will this replacement fit alongside the original ID659 cell in my older SRS-XB3 without modification?

Yes, the pack matches the exact dimensions and 7.4 V specification of the ID659 and ST-06S cells, so it slots into the same compartment with no adapter required.
