18650 Battery Safety

Whilst Lithium-ion batteries are not inherently dangerous, they can be if they are misused or mistreated. It is important you read and understand the information in this section to ensure you keep yourself and your electronics safe at all times.

This battery safety information applies whether you are using 18650, 21700, 20700 or 26650 batteries or any other lithium-ion batteries. 

NEVER KEEP BATTERIES LOOSE IN YOUR POCKET

Always use the case provided to store your batteries when they are not in use. Never put loose batteries in your pocket, or leave them in purses, bags or even drawers in your home. Incorrect storage is the number one cause of all battery-related incidents. Batteries left exposed to other items such as keys and coins can easily short - causing them to explode or burn.

If you like to take multiple batteries out and about with you, you’ll benefit from investing in a larger EVA case, these can carry up to x4 18650 batteries.

LOOK AFTER THE BATTERY WRAPS AND INSULATORS

Wraps and insulators should be periodically inspected for tears or damage. If a battery has a damaged wrap, it should be repaired or disposed of immediately.  The insulator is a round disk on the top of the battery - it separates the positive and negative terminals. If you bridge them with a metal object they will overheat and either explode or leave you with a nasty burn.

DO NOT USE YOUR BATTERIES IN ANY OF THE FOLLOWING CONDITIONS

The wrap insulates the negative terminal holding the insulator in place. Do not use batteries with damaged wraps or insulators. Either dispose of them immediately via a recycling point or return them to your retailer who will be able to repair them with a new insulator and wrap. If you’re confident in replacing the wraps yourself, you can do so using our wrap repair kits, you’ll find a wealth of resources on YouTube demonstrating how to do this. 

NEVER CHARGE YOUR BATTERIES WHEN UNATTENDED

Lithium-Ion cells should be charged on a dedicated charger rated specifically for Lithium-Ion cells. Never leave a battery unattended whilst charging and always be sure to remove the batteries from the charger when the charging cycle is complete. 

Whilst charger failures are rare, they’re not impossible. Recharge your batteries a convenient time when you’re in the room and able to keep an eye on it. Furthermore, when it’s completely charged, remove it from the mains. Overcharging it carries the same risk.
