The Delkin Devices WingmanHD Premium Rechargeable Battery has been designed to the exact specs of your original WingmanHD battery, which means it's guaranteed to work as an additional or spare battery for your WingmanHD Action Camera. This also means that it will fit perfectly into the WingmanHD wall and auto chargers you already own. The battery features high-quality cells, which are more impervious to ware and aging. Not only does this battery last longer between charges, it can withstand more charge cycles over time before another replacement battery is needed. Plus, it's equipped with safety mechanisms that continually monitor and control the battery to prevent overheating, short circuiting, overcharging, discharging and other hazards. The battery is even ready-to-go as soon as you open up the package. There's no initial charging required and you don't have to fully drain the battery before you can charge it again. Just open the package and go. Main Features
