Direct replacement for Plantronics headsets

This Cameron Sino lithium-ion cell is built to fit the Discovery 640E, Discovery 650E, Explorer 50, M50 and Voyager 5200 models. It matches the original 3.7 V specification and carries the part numbers 1704018-0944 and 71468-01 for straightforward identification. Users seeking a new power source for these specific headsets will find the correct fit.

Pre-installed protection circuitry

The pack includes overcharge, over-discharge, over-voltage and short-circuit safeguards that operate automatically once connected. A decoded chip communicates with the headset exactly as the factory battery did, so no extra configuration is required. Shock-absorbing foam in the packaging protects the cell during transit.

80 mAh capacity determines talk time

At 80 mAh and 0.3 Wh the battery supplies the same energy rating as the original Plantronics unit. Buyers who need longer runtime between charges will not gain it here, because the capacity is fixed by the headset’s internal compartment.

Questions about this item

How many charge cycles can the 80mAh lithium-ion cell handle before it needs replacing?

The manufacturer states a new battery reaches best performance after 2 or 3 complete charge and discharge cycles, but does not publish a total cycle-life figure.

What stops the 3.7 V pack from running longer under constant use?

The 0.30 Wh capacity is the limiting factor; once the stored energy is depleted the headset must be recharged.

Does the 27.0 g battery get warm or noisy during all-day operation?

No moving parts or active cooling are present, so the cell runs silently and generates only minimal heat during normal use.
