You've got a stack of WP820 handsets and their batteries are dying mid-shift. The GMC08 slots eight batteries in at once, each with its own LED so you can see at a glance which ones are done. Three charge levels – 20–30% for transport, 60% for storage, 100% for full readiness. Built-in over-voltage, over-charge, and short-circuit protection. Auto temperature control with a cooling fan. Batteries not included – this is the charger
