750mAh 14500 Battery

This 750mAh 14500 battery, from MecArmy, is powerful enough for use in high-drain electronics, including your lower-lumen, compact LED flashlight, such as the MecArmy PT14 (sold separately). The Li-ion rechargeable battery offers a high enough capacity to power your keychain light or other compact portable electronics. The M145 is also equipped with a built-in protection circuit to prevent overcharging and over-discharging. This 750mAh 14500 battery is a more affordable power source than the more popular 18650 size; yet is still a solid rechargeable option if you want to limit your waste production of single-use batteries.


  • Environmentally friendly - choose rechargeable batteries over single-use to limit the amount of waste you produce
  • Built-in overcharge and over-discharge protection prevents damage to you, to your electronic, and to the battery
