chemistry LiMN means reduced risk of venting with flame or explosion.
For maximum protection during charging, use a Li-Po Safe Charging Bag.
****DO NOT leave batteries charging unattended!****
Due to the safety inherent in IMR safe chemistry batteries there is no
protection circuitry added or built in, which provides a slightly shorter
battery length to enable a good fit in most mods.
To ensure longevity, it is not recommended to allow the battery to discharge below 2.5V.
Please note that due to their inherent safety, IMR cells don't have a
protection circuit built in. They should never be discharged below 2.5
volts or cycle life/performance will be reduced. Maximum charge voltage
is 4.25 volts.
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. It is recommended that batteries always be charged using a SMART charger.
