4 Important Safety Tips for Safe use of Li-Ion Batteries
Do not leave charging batteries unattended.
As with any battery, don’t leave 1860s charging unsupervised. Even though most chargers are comprised of fire-resistant materials, accidents still happen. Batteries charge in roughly 3 hours on the slowest setting when completely dead.
Do not leave batteries in extreme temperatures.
Manufacturers warn against leaving batteries in hot environments, which can cause capacity loss, leakage, and rupture.
Do not use a damaged battery.
Neglecting to inspect a battery for signs of water/juice damage or a damaged packing is highly discouraged. Using or charging defective batteries can cause venting
Do not carry batteries with metals
Batteries should not be transported or stored alongside metal objects to avoid short circuiting between the battery terminals.
Are 18650 batteries dangerous?
When it comes to Lithium batteries, how can you be sure they’re safe? This is information that you need to be aware of. For the simple reason that batteries can permanently harm you if they’re not handled correctly. However, users can ensure the best performance while also remaining safe by taking the proper handling precautions and being knowledgeable about 18650 battery safety.
Even though 18650 batteries are safe when used properly, they can be dangerous if misused. They may look like AA batteries, but they require special handling.
Check the insulation
You should inspect your cells each time you remove and reinstall them if you plan to use them individually (i.e., not as part of a battery pack). Verify that the wraps are intact and free of tears, and that the insulator ring at the positive end is intact and free of damage/distortion. The insulator separates the negative (-) outer cell from the positive [+] inner cell.
An insulator ring that is damaged, loose, or missing can result in a direct short circuit, fire, explosion, and injury to people or property. Keep in mind to clean and free of dirt/debris the contact areas (top and bottom).
The battery wrap performs a critical function. As a result, the cell’s body is safe from damage from a voltage spike. If the wrap becomes damaged, stop using it until you can get a new one.
