Again Good Luck. There are a lot of good people on here ready to help. I can't stand being with out my e cig for even a minute.
OK Lucky, I decided to run a test on one of my new Trustfire batteries from HTD. The battery I used in this test has been through 4 charge cycles. I used my Protege with a fairly new atomizer. The resistance of the atty is 2.8 Ohms. How I performed this test was that I tested the battery before the test and then used it on my Protege for 30 minutes runs. I would then take the battery out of the protege and insert it into one of my nicosticks. I took a voltage reading with no load and then pushed the button and checked the voltage of the battery under load with another atty on the nicostick that also had a resistance of 2.8 ohms. I repeated this sequence until the battery protection circuit kicked in. The results are as follows:
unloaded under load
Initial voltage 4.17 3.93
after 30 minutes 4.02 3.79
after 1 hour 3.91 3.70
After 1.5 hours 3.83 3.62
After 2.0 hours 3.77 3.54
After 2.5 hours 3.72 3.48
After 2.5 hours 3.62 3.42
After 2.75 hours 2.93 0.00
This test was conducted while I was watching TV and surfing the web. I usually take 5 to 6 second drags on my Protege. So you could say I'm a very heavy hitter when I'm not busy doing something that requires my full attention. I normally don't push one that hard but since I was testing I naturally over did it.
You can see that the last 15 minutes the voltage dropped off rather quickly.

Hi Lucky -
I've been using the silver protected UltraFire from Protected UltraFire 14500 AA sized 3.6V Li-Ion Rechargeable Battery 900 mAh CR14500 Lithium Ion and just pulled a batt I've been using on and off for the past 24 hours and still have a reading of 3.84... it's still vaping fine.
Yup, I don't have a multimeter but I use the UltraFire protected and put one in last night before bed that I'm still vaping strong on. I have 4 in rotation and usually can't use them fast enough. I don't think I'm a crazy heavy vaper but I run through 2.5-3 ml a day and usually switch out the battery once a day (twice if I just feel like swapping for a fresh one, but the protege has never really required it). I use the protege exclusively, 510 atty dripping constantly. Looks like they are twice as much as the TrustFires from DX but after reading through this thread I'm glad I went that route (and maybe they last twice as long in relation?).
I hate to dissappoint you but the Ultrafires are really no different than the Trustfires. My first 4 bats were Trustfires from DX. One came DOA but at the price I guess I couldn't complain too much. The next order I bought 8 Ultrafire silver batteries from DX. One came in DOA and another one died after one week. I have used them side by side and can find no difference except that the Trustfires fit the Protege better because they are slightly smaller in diameter. Sometimes I have to struggle to get the Ultrafires out of the Protege. 2 of the first 8 Ultrafires have an intermittant issue with the protection circuit.
Otherwise the performance of the Ultrafires seems to be identical to the Trustfires.
Every time you charge one of these batteries you will lose a little capacity. If you are lucky you will be able to do this 300 times before they die. For me I will never get to that point because the drop in performance begins long before the 300th charge.
Just updating and checking in. Someone so kindly sent me a brand spanking new AW battery. It came fully charged at 4.1 v. It's vaping like a champion. I'm 3 hours into it with continuous vaping. It started at 4.1 and is now at 3.8 and still vaping nicely. What I do not understand is when I check the voltage and drop time on some of my trust fires, by the time they get to 3.8 v they are sucking wind and they get there in about 2 hours or so also. WHY at the same voltage on 2 different batteries do I have a pleasurable experience on one brand and not on the other? Could these trust fires even be underrated on voltage? I realize they are on mAh, but voltage? Any thoughts??? Once I have been using the multi meter, I do not see these trust fires dropping as Steve described with one of the batteries he has of mine, but WHY the horrible vape? I would think it would be contacts, but it can't be contacts, because why is the AW one working perfectly?
Hi Lucky,
One thing I've noticed is that my batteries seem to last longer using the 510 adapter than they do using the 801 adapter. Does the 801 atomiser use more power to run, I wonder?
Seriously, I do not think I have a battery problem. I have went through every single step with my multi meter and an electrician and it's not the switch. I truly believe it's my adapter. No one else is having the issues I am with the 14500s or whining that they aren't getting decent vapor and throat hit off their Protege. I am. That is a problem. The 510 actually uses MORE power than an 801 I believe. So that is strange. I know it uses more than a 901.
