It depends on what voltage you are vaping. I have used the DCs but only at around 4 volts and had to keep it topped off often. I would think you should be getting more than 1 day out of them tho.
Like Wharf said, the yellow on mine meters at 4.5. I hope you get it worked out 
What kind of battery issues? We may be able to help you with that too.

DO not ever dry burn a dual coil. The taste goes south if you do it and doesn't get right again. If you keep them wet they last a long time, also I find they are better between 4-4.2 V.
Well, I think I have my battery issue narrowed down to a bad battery. I put it on the charger and sometimes it wont turn red when it is drained. After swaping them around and unplugging the charger it turns red and works fine for a day. Sometimes I get about two minutes from what I thought was 2 charged batteries and then I start the whole not turning red thing again. I have snugged up the cap screw and cleaned every connection. I have two batteries that I have not had any problem with at all. The cap screw was backed out too far and it took me a few days to notice that. Not sure if that led to any of this, but I think I have one bad battery, luckily I have four so I can rotate them.
I burnt up 3 sets of batteries during LR testing. LR is very hard on batteries.
I thought 1.5Ω DCs actually provided 3Ωs of resistance. I'd like to know this because I'm planning on stopping by Kalamazoo Vapor Shop later this afternoon and picking up a box of SMOKtechs. I've yet to try the DCs and I don't want to burn the filler first time out.
The 1.5 DC is two 3 ohm coils in parallel. 3 ohm parallel 3 ohm = 1.5 ohm apparent resistance, with each coil getting half the power; if you're at 4.5 V, the DC draws 4.5 V /1.5 ohms = 3 amps, and each coil is getting 1.5 amps, 6.75 Watts. Total power is 13.5W (a lot). (I'm lucky to be a simple person, happy with my 3.1 - 3.4 ohm standard cartos )

I have been using the dual coils for about 3 months now on my OB at about 4.2V and really like them. They do drain the batteries faster but batteries are cheap and the increased flavor and TH are worth it for me
BTW- I have accidently vaped a dc dry and will give you a burnt taste. However I refill and vape through the burnt juice (no inhale) and the DC is as good as new IMO. The filler does not burn very easily

NO they are 1.5 ohms total , 2 x 3 ohm coils in parallel so they power gets split between the 2 coils this requires 2x's the current to get the same heat to each coil .

Ya but everyone trusts your answers more than ours so we like it when you answer.
