Cameron & Co DS-CS-LOH820SL 3.7V 450mAh Li-Polymer battery

Replacement battery for Logitech H820e

This 3.7 V 450 mAh lithium-polymer cell replaces the original 533-000095 pack in the Logitech H820e wireless headset. It is built to the same 1.67 Wh specification and fits the existing battery compartment without modification. The black housing matches the original appearance. Buyers who need a different voltage or a higher capacity will not be served by this part.

450 mAh capacity and typical runtime

The 450 mAh rating delivers the same talk and standby time the headset was designed for. In normal office use the charge lasts through a full working day before the headset signals low power. Heavy continuous calls or elevated volume levels will drain the cell faster and require mid-day recharging. There is no larger-capacity version of this form factor available from the supplier.

Thermal behaviour and power draw

Lithium-polymer chemistry runs cool during the low-current discharge of a headset; the cell stays near ambient temperature in normal use. No audible noise is produced by the battery itself. Charging follows the headset's built-in circuit at the standard 3.7 V rail, drawing only the current the original pack would accept. Overcharge and deep-discharge protection are handled by the headset electronics.
