Replacement battery for Sony audio models

The Estry SRS-X1 is a 1000mAh 3.7V lithium pack built to original specifications for the SRS-X1, SRS-WS1, MDR-XB950N1 and WH-CH700N devices. It replaces part numbers A-2215-026-A, LIS1553HNPCS, LIS1553(SY6) and LIS1553. The cell measures 47.56 x 32.2 x 6.4mm and weighs 45.4g.

Thermals and safety protections

The pack includes overcharge, over-discharge, over-voltage and short-circuit protection circuits that limit temperature rise during normal charging and playback. Rated at 3.7Wh, it draws modest current and runs cool in typical headphone or speaker use. Certifications cover ISO9001, RoHS, CE, UN38.3 and MSDS.

What the certifications and fitment give you

RoHS approval confirms the cell contains no restricted hazardous substances. CE and ISO9001 marks verify manufacturing quality controls. UN38.3 clearance means the battery passes transport safety tests for shipping. The exact dimensional match ensures the pack seats correctly in the listed Sony models without modification.

Questions about this item

How do I fit the SRS-X1 1000mAh 3.7V lithium battery into my device, and which step often goes wrong?

Power off the device, open the battery compartment, disconnect the old pack, insert the new 47.56 x 32.2 x 6.4 mm cell with the connector aligned to the correct polarity, then close the cover. The step users miss is verifying the connector orientation before pressing it in; reversed pins prevent the device from powering on.

What replacement will the SRS-X1 1000mAh 3.7V lithium battery need later?

The 1000 mAh lithium cell itself is the only replaceable part; when runtime falls noticeably short of the original 3.7 Wh rating, purchase another SRS-X1 pack (part numbers A-2215-026-A, LIS1553HNPCS, LIS1553(SY6) or LIS1553) and swap it the same way.

What limit appears first during sustained use of the SRS-X1 1000mAh 3.7V lithium battery?

The built-in protection circuit cuts output if voltage drops below the safe threshold, if current exceeds the design limit, or if the cell temperature rises too high, so the first limit you hit under heavy load is the over-current or thermal shutdown rather than total capacity loss.
