IMR vs INR

[numbskull]

Just curious as to what the difference is between these two types of batteries. I know it's different chemistry, but is there any advantage to one over the other?

I think INR is just a model specific identifier for Samsung (?) batteries, like VTC for Sony.

This is true; the Samsung INR batteries are IMR/hybrid batteries, as are the NCR batteries from Panasonic (and Orbtronic)

hey Bad! How's it going?!? Nice to see you here!!

As others have said, INR is one of various hybrid battery systems out there. Plain IMR (lithium manganese) are still being made and while they have the high amp ratings of the hybrids, they don't have the higher mAh ratings. That's why most people use hybrids like Samsung 25R, LG HE2, AW, Sony VTC, etc. They are all quite good.

What we should avoid are ICR (lithium cobalt) batteries. They have low amp ratings and generally higher mAh than the hybrids. They are the ones that burn when they vent and can cause explosions.

Here's a lot more information on it all, specifying cathode materials: Types of Lithium-ion. There are other design elements involved too, but cathode material is an important factor.

Thanks all!

IMR are lithium manganese rechargeable, INR are lithium nickel rechargeable Numbskull. Both are high drain cells. IMR chemistry has been around for quite a bit now, and are know for their safety, durability, high output, and lower capacity vs ICR. INR have a higher capacity potential, safety potential, and energy output potential than IMR or ICR but are still in the infancy stages of development. As for now they're very similar to IMR save for a few issues. INR batts tend to have more inconsistencies between cells, and do not last as many cycles as an IMR (AW IMR rated for >500 cycles, Samsung batteries rated to lose 40% capacity after 250 cycles).

Amen to that! Enjoy the day!

Cyrus Vap sir I have missed talking with you. Glad to see you're still vaping.

Vaping my brains out, totally cig free since day one. Not in small part due to you my friend. Not to rabbit trail the thread but wondering what kind of gear you're using these days, besides the guessable "everything good"

Current work set up is a edna dna30 with a kraken sir (only genny that doesn't leak). Also have a provari 2.0 with a zap that was gifted to me (save the zap) by a friend, a provari 2.5 mini with a kayfun lite plus, sapphire zen 2 altus, and nemesis with a stratus 22. Never got into box mods, just don't like how they fit in the hand.
