Grandstream GMC08 Battery Charger for WP820

Grandstream GMC08 8-Slot Battery Charger with Charge and Discharge Control

The Grandstream GMC08 is a multi-battery charging unit for compatible removable batteries used by the Grandstream WP810, WP820 and DP730 handsets. Eight independent slots allow organisations to charge or discharge multiple lithium-ion batteries simultaneously, helping maintain a prepared supply of spare batteries for mobile users.

A three-position capacity selector allows batteries to be prepared for transportation, longer-term storage or everyday use. Individual dual-colour LED indicators show the status of each slot, while integrated electrical and temperature protection helps support reliable operation in busy professional environments.

Key Features:

• Eight independent slots for charging or discharging compatible lithium-ion batteries
• Supports batteries used by the Grandstream WP810, WP820 and DP730 handsets
• Processes multiple batteries simultaneously
• Three selectable capacity levels for transport, storage and everyday use
• Low setting provides approximately 20% to 30% capacity for sea, land or air transportation
• Intermediate setting provides approximately 60% capacity for longer transportation periods and storage
• High setting provides approximately 100% capacity for normal daily use
• Eight independent dual-colour LEDs show charging, discharging, completion and error status

The GMC08 charges removable batteries rather than the handsets themselves. This allows users and administrators to rotate prepared spare batteries between compatible handsets without leaving each phone connected to a charger.

Key Benefits:

• Simultaneous battery handling helps reduce charging delays across larger mobile-phone deployments
• Selectable capacity levels allow administrators to prepare batteries appropriately for transport, storage or immediate use
• Built-in over-voltage, over-charge, over-current and short-circuit management helps protect batteries and the charging unit
• Leak protection provides an additional safeguard during charging and discharging
• Automatic temperature control uses an integrated cooling fan, with device shut-off under extreme temperatures
• Individual status indicators make it easy to identify completed batteries or charging errors

The package includes the GMC08 battery charger, 12V 2A power adapter and quick installation guide. Batteries are not included, and only compatible batteries specified by Grandstream should be charged or discharged with the unit.

Compatible batteries and other supporting products can be found within the Grandstream IP Phone Accessories range. Comms Express also offers an extensive Grandstream WiFi Cordless Phones range for mobile business communications.

For customers wishing to consider other manufacturers, the wider VoIP Business Phone Systems range includes IP phones, headsets and related communication products from a variety of leading brands.
