mmmm, Lets just say you can get different results using different batteries and atties.
So to answer CDs post, of why more people dont usually use aa batteries to mod?
the trend seems to be going toward smaller mods, so using multible AAs instead of
one 3.7v defeats that purpose.
The Puck is small. It uses AAAs, not AAs.
As far as using alkalines, yes they work but I only recommended them for emergency use do to the cost but they are great in a pinch.
There is no harm in using them though even though your voltage is quite a bit higher with them. The Puck runs about 4.6 to 4.7 volts under load with freshly charged NiMh AAAs. It stays pretty constant drop only tenths of volts until the batteries die completely, all at once. I usually can vape (and I vape pretty constantly) until the same time the next day that I put the batteries in (call it 24 hours with sleep).
I haven't tested the Puck using akalines under load so I probably need to do that to see what the voltage is dropping to. You most likely are not running 6 volts and probably more like 5 or less under load but I will check it out.
Akalines are great for emergency use but the cost will add up if that's all you use so you are smart to get the NiMhs but I would have bought them at a grocery store or hardware store since Radio Shack is very expensive normally for their batteries. You can get a set of brand name NiMh 4 AAAs at Lowes Home Improvement stores for less than 10 bucks.
All NiMhs that I have bought so far have worked out pretty good though.
As always, keep your cart wet and you will get better battery life. A wet cart only needs about 3 seconds button press but longer when it is drying out which will eat batteries faster.
