Replacement battery for SIMOLIO headsets

This Cameron & Co DS-CS-SML823SL lithium-polymer cell replaces the SM-001BAT pack used in several SIMOLIO models including the SM-823, SM-824 and SM-828 series. It delivers a nominal 3.7 V and a rated capacity of 300 mAh, matching the original 1.11 Wh specification. The pack is supplied new and is fully OEM compatible. Builders who need a higher-capacity cell or a different form factor cannot use this unit.

Slim black pack with integrated connector

The battery measures 40.00 mm by 21.70 mm by 5.80 mm and is finished in black, matching the original housing dimensions. Its Li-Polymer chemistry allows a thin profile that slides into the headset's battery compartment without modification. The integrated connector plugs directly onto the device's internal header, so no soldering or adapter cables are required during installation. Users who prefer a user-replaceable door or an external charging case will find this internal pack unsuitable.

Verify the exact SIMOLIO model before ordering

The supplier lists compatibility with SM-823, SM-823D, SM-823D Pro, SM-8245, SM-824D1, SM-824D2, SM-828D1, SM-828D2, SM-863D and SM-905TV. It explicitly states the pack cannot be used for Simolio IN EAR headsets such as the SM-823 Pro. Check the model number printed on your headset and confirm the original battery part number is SM-001BAT. Buyers with unlisted SIMOLIO models or non-SIMOLIO headsets should not purchase this battery.

Questions about this item

What voltage and capacity does this Li-Polymer cell deliver?

The cell is rated at 3.7 V and 300 mAh, giving 1.11 Wh of energy.

Will the 40.00 mm by 21.70 mm by 5.80 mm pack fit my SIMOLIO SM-823 or SM-824 series headset?

Those dimensions match the original SM-001BAT pack used in the SM-823, SM-823D, SM-824D1, SM-824D2 and related models.

How do I install the battery and what common mistake should I avoid?

Open the headset battery compartment, disconnect the old pack, connect the new pack observing correct polarity, then close the compartment; the frequent error is reversing the connector.
