Powerful and Protected

The SUNWAYMAN 18650 Lithium Ion Battery is the brand's first ever rechargeable battery, although you wouldn't think it based on its sophistication.

Safety is as much a key feature of the battery as power, featuring PTC Overcurrent Protection as well as a specialized pressure relief valve to prevent damage from sudden temperature increase. The 18650 is capable of being recharged up to 500 times before dropping to 80 percent of its initial capacity, allowing for extensive use before needing replacing. The perfect companion to your SUNWAYMAN LED flashlight, this 18650 battery is a must have!

Functional 1850 Battery
January 7, 2020
I got a Sunwayman AP-18 18650 battery and it appears to be well made and without visible defects. I have recharged it several times without problems and the size is compatible with all of my flashlights that take 18650's. I haven't measured the run time, but it has powered a flashlight, that is used frequently, for weeks, keeping it bright. So far, this seems to be a functional battery.
