Battery Warning

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Here are a few tips:

  • Never completely discharge batteries (usually below 2.5V for li-ion or 2.0V for LiFePO4, check datasheet)
  • Charge fully (usually to 4.2V for lithium ion or 3.6V for LiFePO4) before first use
  • Never charge batteries to more than their full charge voltage
  • Do not charge unattended
  • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
  • If you must store your battery for a long time, only store in a case or individual box in a cool and dry place at approximately 3.5-3.7V for li-ion or 3.2V for LiFePO4
  • Use only high quality battery chargers
  • Do not expose to heat
  • Do not connect the positive contact to the negative contact without an appropriate load
  • Never exceed the battery's specifications
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
  • Always charge these batteries on and within fireproof material
  • Never leave rechargeable batteries in a recharging station unattended
  • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
  • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
  • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
  • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
  • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

The perfect solution

Wanted some high-drain 18650's but needed button tops for my flashlight. Magnets or spacers might've worked but this is a more secure solution. Wraps look good. Price was very reasonable.

  • What device/application do you use this with? Flashlight, powerbank

Time is the ultimate judge!

So far so good. I've only had it a few weeks. I'll get back to you in about a year! I've learned over the years that I can't judge a battery for at least 6 months to a year. They can work great for 6 months or year and then they degrade or lose capacity faster than they should. I expect this to work well for 2 years. That's about all I get out of them with my high-powered demands.

  • What device/application do you use this with? Wurkkos FC11.Torch
