Short battery life?

[Dion]

I received my Copper just a few days ago but immediately noticed that the battery life was much shorter than I expected. On a fully charged battery I get maybe 30 minutes of vaping at most.

The batteries that im using are 2xCR2 800mah Ultrafire batteries. Is this normal?

doesn't sound normal to me i get about a day and 1/2 with my 800mA cr2. did you let the battery's charge fully befor you started using? if not you may have damaged the battery's. if you did you may have bad batteries try to get a new set or if you vaping a lot then it might be give it a longer rest period.

be very careful not to pull them below 2.7v each also..which requires frequent removal/checking. they'll make vape ..good vape, even when theyre down to 2.0v

which is why i dont stack batteries lol

Is your atty resistance around 3 ohms?
Can you measure copper resistance w/o batt and with atty?
Do both batts have similar voltages.
