3D cell to 26650 Adapter for Maglite and other Flashlights, 3D Printed in USA.

This is a single 3D printed adapter for your 3 D cell flashlight that allows it to run on a single protected 26650 Li-Ion cell. This listing is for a single adapter complete with brass hardware only – flashlights, batteries and any other items shown in photos are not included. 26650 cells are lighter and more powerful than typical alkaline D cell batteries and they are rechargeable. No need to buy any more heavy, leaky, expensive, wasteful single use alkaline batteries! This adapter is sized for protected 26650 cells that are typically about 69-71 mm long with a button top or positive terminal raised by 1 mm or more. Q uality name brand protected cells are strongly recommended as they provide important safety features that help prevent potentially dangerous over discharge and short circuits. This adapter has built in reverse polarity protection that is intended to help protect your light if a cell is inadvertently inserted backwards. A button top or raised positive cell contact is required to make proper contact. [To see if the reverse polarity protection feature works with your cells, test with a multi meter outside of your light – never intentionally insert a cell in your device with polarity reversed, as the reverse polarity protection may not work with some cells in some lights.] Adapter is permanently assembled , please do not attempt to disassemble. This adapter is intended for use in unmodified, current regulated consumer flashlights and should not be used for vaping, charging or for any high current application. Quality name brand protected cells should be used to help prevent potentially dangerous over discharge of the cell. When the light begins to dim, turn it off and charge the cell as soon as possible. Do not use damaged, over charged, over discharged or counterfeit cells! Before use, ensure that the Voltage of your cell or cells do not exceed the operating Voltage of your device! ⚠ Warning! This is not a toy. Keep out of reach of children. CAUTION: Batteries may explode, catch fire or leak, and cause serious injury or death, if recharged, over charged, over discharged, short circuited, disposed of in fire, mixed with a different battery type, inserted backwards or disassembled. Replace all used batteries at the same time. Do not carry batteries loose in your pocket or purse. Do not remove the battery label. Keep batteries away from children. If swallowed, seek medical attention immediately. The adapter is 3D printed from PETG filament which is tougher, withstands higher temperatures (up to 160F) and resists most solvents better than the more common PLA filament. The positive contact hardware is solid brass. The rear of the 26650 cell extends from the adapter by design to allow easy removal, to better radiate heat and to allow for the widest possible variation in cell length without interfering with the connection of the cell’s negative terminal with the tail spring. Cutouts on the sides allow the cell to be easily observed for proper position when inserting and the various flutes and scallops are intended to minimize weight. Note that there will be minor cosmetic imperfections incidental to the 3D printing process – these are not defects and do not impair the function of the adapter. Colors, markings, design and appearance may vary from photos. Adapter designed and 3D printed in the USA. If you have any questions or concerns please contact me before ordering.
