Pros and cons………
good and bad………
charger compatible …….
what’s the difference ?
thanks
Regular LiIon has more capacity. IMR can deliver higher current. Thats about it with the difference.
Charge with the same charger (IMR is just a type of LiIon) unless you have something fancy (there are cells that have to be charged to 3.6V and such).
IMR is just one of the types of LiIon cells. They generally have lower capacity but higher discharge rates than ICR cells. The IMR is usually considered to be a little safer and more tolerant of over discharge.
The ICR cells have much greater capacity than IMR cells but lower maximum discharge rates. ICR cells do not handle over discharge well at all, which is one of the reasons they are available with protection circuits.
They both can be charged with the same chargers.
I just realized I've been pulling ~3A from a li-on 14500 in my edc. Oops.
too high of a current for a sc52 or a sk68 clone?
SC52 is regulated -> no problem.
SK68.. should work but might get hot. You have a DMM? Check the amps with one of your IMRs at a voltage of about 3.8V first, if you get ~2A, a fully charged IMR will be too much.
thanks to all for the information
And now comes the resulting question: how much current is much and how much is not much???
I have no problems with 2-3A from 14500, the nitecore and the keepowers(sanyo14500p).
Just checked the Sanyo and there is a discharge curve for 2C in the datasheet but no real maximum current mentioned…

2A: OK
3A: too much
If you assume 2C for regular LiIon cells in 18650 and 3C for smaller sizes, you should be on the safe side.
