Direct replacement battery

The Cameron & Co DS-CS-SML825SL is a 3.7 V 600 mAh lithium-polymer cell built to replace the original SM-003-BAT pack in SIMOLIO big over-ear wireless TV headsets. It fits the SM-825D Pro, SM-829D1, SM-829D2 and SM-905TV models and restores the 2.22 Wh capacity the headphones were designed around.

Low self-discharge chemistry

Lithium-polymer construction holds its charge during storage and delivers steady voltage through a typical evening of TV listening. The slim 6.80 mm profile fits the original battery cavity without forcing the enclosure, so the headset closes normally and no extra heat is generated during charging cycles.

Drop-in fit for listed models

The 44.60 × 27.30 mm footprint matches the factory compartment exactly, requiring no soldering or adapter cables. It cannot be used with SIMOLIO in-ear variants such as the SM-823 Pro, SM-823D Pro, SM-824D1, SM-824D2, SM-828D1 or SM-828D2, so buyers with those models must source a different pack.

Questions about this item

How do I install the DS-CS-SML825SL battery in my SM-825D Pro, and which step is often missed?

Open the headset battery compartment, disconnect the old pack, connect the new 3.7V 600mAh Li-Polymer unit observing the correct polarity, then close the cover securely.

What maintenance or replacement will the DS-CS-SML825SL need over time?

The 600mAh Li-Polymer cell will gradually lose capacity; expect to replace the pack when run-time drops below your needs, typically after several hundred charge cycles.

What limit appears first during a long TV session with the DS-CS-SML825SL?

The 2.22Wh capacity sets the maximum continuous listening time; once depleted the headset must be recharged before further use.
