They do drain batts fast. My GLV2 lasts about 12hrs with 3ohm single coil and 6hrs with 1.5 ohm dual. Does triple mean it will only last 3hrs??
They're probably using three of the high ohm coils which would work out to about 1.6 ohm. That should mean your battery will last about the same. The increased surface area should provide more vapor, so in theory it could mean shorter drags and increased battery life. I'm planning on fixing my PT and trying them on it--should be a fog machine lol.
