Dimensions: 20.4mm x 70.1mm
Note: These IMR cells have much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher ending voltage when charged in certain chargers (especially older versions of the WF-139 charger). Please check the voltage of your 18650 IMR battery right out of the charger to see if they are above 4.20V when fully charged with your charger. You can do this with a Multimeter Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even damage them. DO NOT use the charger if it is overcharging IMR cells.
Battery Safety: Our 20700 batteries are approved by CE and comply with RoHS and ISO9001/2000. Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of lithium-ion rechargeable batteries in charging, discharging and assembly before use. Ã¢ÂÂ¢ Always charge in/on a fire-proof surface. Ã¢ÂÂ¢ Never leave charging batteries unattended. Ã¢ÂÂ¢ Store safely in battery containers when not in use. Ã¢ÂÂ¢ Never put batteries into loose pockets or bags, keys, metal objects can cause explosions/sparks. Ã¢ÂÂ¢ Discontinue using a battery if it fails to retain a charge or looks damaged. Ã¢ÂÂ¢ Dispose of used batteries only at approved recycle locations, containers. Ã¢ÂÂ¢ Always use lithium-ion batteries with a control circuit (protection PCB) to assure safe charge, discharge. Ã¢ÂÂ¢ We are not responsible for damage if there is any modifications made to batteries/chargers. Ã¢ÂÂ¢ We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries/chargers.
Please have a basic understanding and knowledge of the batteries you are using and how to take care of them properly. Custom Vapes will not be held responsible or liable for any injury, damage, or defect, permanent or temporary that may be caused by the improper use of a lithium-ion batteries.
Warranty: Due to the nature of todays low resistance sub ohm builds, the use of third party units/mods or non approved chargers, no returns are accepted on any Li-Ion batteries unless the product was defective upon receipt or dead on arrival (DOA) and we are notified within 48hrs. For more information please refer to our returns policy.
