• Always use this battery with compatible Barebones products only.
• Charge the battery through the product’s USB port—avoid third-party chargers.
• Fully charge the battery before first use for optimal performance.
• Store in a cool, dry place when not in use. Avoid extreme heat, direct sunlight, or freezing conditions.

• To extend lifespan, avoid running the battery down to 0% repeatedly. Recharge when power runs low.

Q: Is the wrapper on the battery supposed to be removed?
A: No. Do not remove the wrapper. Doing so will permanently damage the battery and cause it to be unusable.

Q: Can I charge this battery outside of my Barebones product?
A: No. This battery is designed to charge safely through the USB port of your Barebones lighting products.

Q: How long will the battery last before needing replacement?
A: With proper care, the battery supports approximately 500–800 charge cycles, which equates to years of regular use.

Q: Will this battery work in other 2-18650 devices?
A: No. It is designed specifically for Barebones products and should not be used in non-Barebones devices.

Q: What happens if the battery won’t hold a charge?
A: If your battery is no longer charging effectively after normal use, it may have reached the end of its charge cycle life.

Q: Is it safe to leave the battery charging overnight?
A: Yes, the built-in protection circuits in Barebones products help prevent overcharging. However, for best practice, unplug when fully charged.

Q: Can I throw my Li-ion 2-18650 battery in the trash?
A: No. Lithium-ion batteries should never be thrown away with household garbage because they can leak harmful materials or pose a fire risk.

Q: How should I dispose of my Barebones 2-18650 battery?
A: Take used batteries to a certified recycling center, local hazardous waste facility, or designated battery drop-off location. Many electronics retailers also offer free battery recycling bins.

Q: Why is proper disposal important?
A: Recycling prevents harmful chemicals from entering the environment and allows valuable materials (like lithium, cobalt, and nickel) to be reused.

    Barebones Railroad Lantern battery issue

    Battery failed after only being used two times in less than a year. I notified Barebones and after confirmation of my purchase receipt, a free replacement was sent. It now works fine and hopefully it was a one off on the failure of the battery.
