World highest capacity Japanese cells. Protruded button top.
Measures only 68mm in height!
These second generation 18650 cells offer world-highest capacity at 3400mAh.
Only 68mm in height
We are the first to offer protected 3400mAh 18650 li-ion with only 68mm in height. That makes it highly compatible with all 18650 flashlights and chargers in the market.
Button top design
The protruded button top design makes it work with any flashlight that uses hardware anti-reversed battery polarity protection. It also ensure good conductivity when multiple batteries are used in series.
Our 3400mAh cells give the highest capacitor, especially during heavy current loading. It is tested to yield 3400mAh at 0.2C of constant current discharge (see our own discharge testing below).
High voltage platform
The ET 3400mAh 18650 offers high voltage output even under heavy loading. This offers longer constant regulated output runtime in a single cell application (buck circuit type).
ET 3400mA batteries, when discharged at 1.5A, yields 3303mAh capacity. When discharged at 680mA, it yields full 3400mAh capacity.
