I want to get a charger that will accept both 14500 and AA batteries. Can I use both sizes in most Olight, Fenix and Nitecore 2AA lights?
Thanks very much.
You would only be able to use one 14500 3.7v with a dummy AA. Using two 3.7v 14500 will put the voltage around 7.4v and will more than likely fry the LED. I recommend using Eneloop AA rechargeables
14500 are the lithium ion version of a AA that are 3.7v
Yes, be careful with this. Look up and know the voltage range each light is rated for and don't exceed the maximum. Using one cell and a spacer in a 2-cell light can be a good option sometimes.
No. Most only work with alkalines, NiMH, and maybe lithium primaries. Some can go up to 4.2 volts. Very few can handle 2 14500s. The Fenix LD22 V2.0 will work with 2 14500s.
