Just make sure they are compatible with the TLR-1 to avoid any issues.
Battery Storage Tips
Proper storage is essential to prolonging the life of my batteries. I learned that keeping them in a cool, dry place away from direct sunlight helps maintain their performance. Additionally, I always check the expiration dates before purchasing to ensure I’m getting fresh batteries.
Replacement Frequency
I’ve found that keeping track of how often I replace my batteries is important. I usually replace mine every six months, even if I haven’t used them extensively. This practice ensures that I’m never caught off guard with a dead light during critical moments.
