  1. A very good battery, A safe battery.Review by
    Fenix make very good quality batteries. This is their newest one to their range. It gives my PD36R good long runtime. It has a lot of safety features built in to protect the battery and the light you put it in.

    Here's a fun fact, this form-factor of battery (21700) was designed for use in Tesla vehicles! Now we get that power cell driving newer innovations in hand-held lighting.
