They tested the cell the same way he would, by discharging it on a test rig while plotting a curve.
Those Aspire cells are pure bull shit, in my opinion.
Ecf may be chock full of dicks but the battery testing methodology is sound. Just another Chinese company taking advantage of Western willingness to believe anything on a label. Regardless of the discharge test mimicking use in a mod or not, aspire says theyre a.constant 40A, so they should be. Why forgive them lieing just because we.don't constantly discharge a cell? You'll be needing a decent constant discharge if your mod ever starts auto firing.
There's no traceability or accountability when it comes to this battery.
The chinese are bending people over big time as they trip over themselves trying to find as high an amp limit cell as they can.
You're a lot safer buying 25Rs and exceeding the continuous than you are buying Aspire 18650 IMO .
