They're 20 amp cells according to mooch, I wouldn't touch them.

Thoughts on Andrew Wan?
Does that wrapper not contain a reliable, quality 20 amp cell?
Does MXJO not have a good rep?

That's the key, I'm buying some Aspire 1800 mah cells because I read mooch's testing and know that for the way I vape they'll work fine. I know that MXJO cells are crap simply because I'm getting 2200 mah and I wouldn't dare run them for anything requiring 15+ amps. Aspire batteries are the only re-wraps I will touch, they're not actually re-wraps though. When it comes to batteries ALWAYS do your' homework, it'll save you a trip to er.

I smell something fishy.
I'd like pictorial proof you're measuring capacity including, but not limited on v low and v high readings, device power setting age and cycles on cells, capacity reading (pictured) name of device you're using to measure capacity.
Anything you can provide if you don't mind.
Last I checked...
Though it's been a while...
MXJO had a good rep and only wrapped good name brand cells according to independent testers. (Hkj, dampmaskin, Mooch, etc.)
So this baffles me TBH.

Thanks for all the opinions folks! At least there was only one useless comment so far!
I'm actually interested my self.
Can't do the test now I will once my other MXJO battery is charged up. here's all the other details before I do the test so you know what I'm using for the test.
They're the three post cells authentication confirmed through MXJO's website, they have around 150-200 cycles on them. That's a rough estimate since I usually charge around 3.7 if I can.
Device is a VF lite set to 14 watts. Resistance of the tank is 2.1 and it's firing at around 5.5 volts. Rounded up that's a four amp load, nothing to serious.
Charger is a Xtar VC4, I usually charge at one amp, unless I'm charging two other batteries, in which case it's a .5 amp charge.
Test will be done after the cell is fresh of my charger, I will read the voltage before.
Cell will be discharged until the device says "weak battery." Voltages will be read with my TEK model No. 10709 multimeter. Mah will be done through the charger it's self. Stay tuned should have the results by Monday or Tuesday.

My only concern is the "fairness" of the test given the cycles on the cells and that their entire lives they've been at or above storage voltage.
At 150 cycles at that charge state, I'd expect 10% or so capacity loss.
More if some time had passed.
When did you notice this behavior?
Tapatyped
When I bought the cells they were at about 3.5 from what I remember, which is the proper voltage. I store them at 4.2 BUT they're not sitting long at that voltage, maybe eight hours max. They've been used all their life and they get charged between 3.5-3.7, except when I forgot to charge the other one then it's down to 3.3. So capacity should be fine might have dropped %10 at the most I would say. I only noticed when I did a full discharge after maybe 10 cycles, and the charger read 2500-2600, from what I remember. That would be acceptable if I was pushing these cells at 15 amps, not four amps.
My six married hg2 batteries get around 2800 mah under mixed load. My four, married, aging, hg2 that have around 300 cycles get around 2400. They've been abused (25 amp pulses) too. They're going to wind up divorced and used in low wattage applications until capacity hits the 2000 mark.
So vtc5 under the wrapper labeled 3000mah, I presume?
Or would you say more likely old stock when they were sold?
Tapatyped
I have not took the wrapper off so I don't know what's under there, going by mooch's testing I would say vtc5. They're not bad cells, but you can better cells for the same price. The only cells I would buy besides the "big three" (LG, Sony and Samsung) is the Aspire cells since they do 25 amps and according to Mooch they hold voltage very well, plus the capacity is what they say it is. The Hohm tech cells are also good from what I hear. I compare it to pop, would you buy generic cola if it was the same price as Coke?
