Important Safety Warning for 18650 Li-Ion Batteries:

Li-Ion batteries, including the Panasonic NCR18650B and the Cameron Sino Range, require correct charging and discharging practices to ensure safety. Improper use can lead to risks, including explosion. It is vital that users understand the proper handling, charging, and discharging of these batteries before creating battery packs. We are not liable for damages resulting from misuse.

Before using this battery, ensure it is compatible with your device. Research is essential as no guarantees of compatibility are provided. Remember that individual Li-Ion cells are UN38.3 certified for transport. Modifying the cell by more than 20% or adding extra cells voids this certification, prohibiting their use on aircraft, either as carry-on or cargo.

Handling these unprotected Li-Ion batteries demands caution due to their sensitivity to charging irregularities. Mishandling can cause them to burn or explode, posing risks to personal safety and property. Charge these batteries on a fireproof surface and never leave them unattended while charging. Use only a smart charger specifically designed for this type of Li-Ion battery. Avoid mixing old and new, or used and unused batteries.

Proper disposal of Li-Ion batteries is crucial when they are no longer needed. Do not dispose of them in fire. Disposal regulations vary by country, state, and local governments. Please consult your local authorities for proper disposal methods. Many retail stores also offer free recycling of rechargeable batteries.

We are not responsible for any damage resulting from the modification of batteries or chargers in any form. This includes, but is not limited to, making battery packs. Our responsibility does not extend to damage caused by misuse or mishandling of Li-Ion batteries and chargers.


Please make sure that the correct cell has been ordered for your application.
