8 Slot WP8XX Battery Charger

The Grandstream GMC08 is an 8-slot multi-battery charger designed for compatible Grandstream cordless IP phone batteries. Supporting the WP810, WP820 and DP730 battery models, it provides a convenient way to charge, discharge and manage multiple spare batteries. Ideal for businesses using cordless communication systems, the GMC08 helps keep replacement batteries charged and ready for use.

Charge Up to 8 Batteries Simultaneously

The GMC08 features 8 independent charging slots, allowing users to charge or discharge up to eight compatible lithium-ion batteries at the same time. This makes it particularly useful for workplaces operating multiple cordless IP phones, including warehouses, hospitality venues, offices and other busy commercial environments. Centralised battery charging helps simplify battery management and reduces the need for separate chargers.

Three Selectable Battery Capacity Levels

Designed for flexible battery management, the GMC08 offers three charging capacity settings. These include approximately 20–30% for transportation, 60% for extended storage and 100% for everyday use. Users can select the appropriate level using the built-in capacity switch, making it easy to prepare batteries for immediate use, storage or transportation.

Intelligent Charging Protection

The Grandstream GMC08 includes built-in over-voltage, over-charge, over-current and short-circuit protection, alongside leak protection. An integrated cooling fan provides automatic temperature management, while the charger shuts down under extreme temperature conditions. These safeguards help support reliable charging and protect compatible batteries during operation.

Clear LED Charging Indicators

Each battery slot has its own dual-colour LED indicator, providing clear information about charging and discharging status. Users can quickly identify when a battery is charging, discharging, fully charged or experiencing an error. This makes it easier to manage multiple spare batteries without checking each one individually.

Simple Installation and Everyday Operation

The Grandstream GMC08 battery charging station features a compact design measuring 220 × 190 × 54mm. It comes supplied with a universal 100–240V power adapter, delivering 12V DC at 2A. Simply connect the charger, insert compatible batteries and select the required capacity level.

Practical Battery Management for Cordless IP Phones

With eight independent charging slots, selectable capacity levels and integrated safety protection, the Grandstream GMC08 battery charger is a practical accessory for organisations using compatible Grandstream WP810, WP820 and DP730 cordless phones.
