Bench Test Results: AW 12A 800mAh Button Top 18350...only a 6A 700mAh battery

These tests below only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.

Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.




Bottom Line
Both of the cells I tested delivered about 700mAh of capacity and were poor performers with an exaggerated current rating. Their large voltage sag made them essentially unusable at 10A, as displayed by the huge drop in the Wh delivered between 5A and 10A.

Both cells had the anti-counterfeit hologram with microprinting and were purchased from Avid Vapes.

The two cells I tested delivered 696mAh and 704mAh for a 160mA (0.2C) discharge down to 2.5V.

I am estimating this cell’s ratings at 6A and 700mAh. Current ratings for high internal resistance batteries like these are a combination of the temperature the battery runs at and how badly the voltage sags, i.e., its Wh specs.

Two cells were purchased for the purposes of testing by me.

Performance Specs
- DC Internal Resistance = 52.9mOhms (milliohms) average for the two cells.
- Total energy delivered down to 3.2V at 5A continuous = 1.4Wh (Watt-hours) average
- Total energy delivered down to 3.2V at 10A continuous = 0.2Wh (Watt-hours) average

Good timing, I actually just pulled these out from my drawer the other day to use on my Atto unregulated mod SKX clone. Wonder if my batteries spec out to your? Mine are over a year old purchased from RTD Vapors. I vaped on mine with a .72 ohm coil & got a few hours run time the mod never got hot.

Thanks Mooch, confirms my test results left on your 18350 shootout thread, I posted there with a link to this thread for those interested. I can only discharge up to 2.5 amps with my current setup, but your results are a bit better, but similar, my 2 batteries sat for a long time. I was highly suspicious of the 15C ratings on this battery from the beginning.

I’m mostly disappointed as the AW branded batteries have always come highly recommended in the past.

Yeah, I'm pretty disappointed in these test results as well. AW generally had been believed to be the top performer in the 18350 and 18490 size batteries.

I don't use either size any longer as my Provari's are retired.
