Paleblue Voyager C USB-C Rechargeable Batteries (2-Pack)
The Paleblue Voyager C USB-C Rechargeable Batteries are lithium-ion C cells that recharge from a USB-C cable and hold a true 1.5 V output for devices built around alkaline C batteries.
Each cell stores 4,000 mAh (6.0 Wh) and is rated for more than 1,000 recharges. The included 2-to-1 USB-C cable charges both cells from one USB-C power source, and a full charge takes four hours.
Alkaline-Style Discharge
Voyager cells follow a discharge curve modeled on alkaline batteries. Voltage eases down as the charge is used and drops sharply only at the very end, so devices with a low-battery warning still signal before they shut off.
Older rechargeables with a lower output voltage can leave some devices running poorly.
Protection and Status
Each battery guards against overcurrent, short circuits, overheating, over-discharge, and overcharging, and it stops charging when it is too cold. A sealed steel casing with pressure relief contains the cell if it fails. An LED ring flashes green while charging, turns solid green when full, and flashes red on a fault. Paleblue covers Voyager batteries with a limited lifetime warranty against manufacturing defects.
