IMR Battery Question!

[greghemmings]

How long do IMR batteries last?? I have been using the same three batteries, two 490's and a 650 continuously for three months. Now they don't seem to hold a charge as long. Is this normal??

What brand are the batteries? Two of my18650 AW IMR's lasted almost two years before i couldn't get an all day vape.

They are AW's...

My AW 18490's are over a year old as are 4 of my Grey Panasonic 18650's and they are all still going strong.

Treated well, they should last you at least 300 charge cycles. What charger are you using? What voltage do they measure immediately after charging? Are you using mechanical mods or regulated?

I would expect a longer life before the dropoff was noticeable with AW IMR's, but I vape at 1.5-2.2 ohms. Three possible causes would sub-ohm vaping, which may shorten battery life, a crappy charger or the possibility that they are counterfeit. If you got them through a major AW reseller, counterfeiting probably isn't the case.
