AW IMR fast dropoff?

[DeadPerfect]

i'm using a Silver bullet till my Vamo arives.. been using the black AW IC 18650 protected batteries with it as suggested when purchaced. they work fine. but recently learned the AW IMR's will output more power, which it does. and thats great. i get a better hit from the SB. but after a 1/2 hour, i start getting weak hits, so i toss it back in the charger, and throw in a protected battery while it tops off again. and the hits after a 1/2 hour are alot weaker than the charged protected battery.

is this normal with AW IMR in a non vari-volt mod? or do i possible have a bad battery? got it from RTD Vapor. thanks

My AW IMR takes a while to drop to 3.7v

You should get a multimeter and check the batt.

But given the protected batts usually have a higher mah, the IMRs will die faster.

imr is 2000 mah. protected is 2200. i think its a bad battery. ill check it when i get the vamo.

is this normal with AW IMR

Yup. Unless you have an extreme need for a high discharge rate the Li-Ion's mAh trumps the IMR.

Here it is visually.

thanks.. but a 1/2 hour, moderate vaping? doesnt seem right. black one goes hours b4 any noticeable dropoff...

When fully charged the battery voltage is around 4.2 volts. Normal working voltage is 3.7 volts. Most batteries will drop from the fully charged voltage (4.2) to somewhere around the working voltage (3.7) fairly quickly. Once near the working voltage (3.7) the discharge rate slows down and the battery will maintain something close to it while slowly dropping till it hits the recharge voltage. If you are sensitive to the strength of the "hit" you will notice this fast dropoff in voltage then it will maintain the same "hit" strength until nearly the recharge voltage then drop off quickly again. This is one of the things that the variable voltage/wattage mod was designed to fix.

Might want to do a little checking with a multimeter while vaping with a fresh battery to prove this. If your battery is malfunctioning, none of this applies of course.

Yea pretty much by the second hit.

After about 90 minutes of resting, the battery will drop to close to its working voltage without any use.

Using it, it happens a lot faster. I've heard it's slightly risky to do that and let mine relax if possible. How much risk it is, I don't know.

Have no idea what "working voltage" means. Our batteries are sold and labeled by their nominal voltage, usually 3.7V, which is more or less an average over the life of the charge. If you have a battery that comes off the charger at 4.2V and after a simple rest drops below 4V you might as well toss it and get a new one. That's assuming only that one battery does that.

That said pulling a battery off the charger early can also show similar results. The charger actually terminates based on current. BatteryU uses the term full saturation.
