You nailed it yzer that explains it I charge my battery over night & leave it in the charger till I wake up in the morning I wont do that any more thanks for the explanation!Unfortunately, the TR 001 would continue to trickle charge batteries as long as they were left in the charger with the green light turned on. Leaving the batteries in the charger for several hours after the green light went on resulted in batteries overcharged to 4.3V.
4.3V is too much charge on the battery. Before going further I would measure the battery voltage with a DMM as well as the voltmeter in the Sigelei to see if they agree. I can't do without a DMM for vaping. I test every carto coil before I fill a carto for the first time.
I posted before that I had problems with a two year-old Trustfire TR 001. When new it would bring batteries to 4.17V or so at the time the red light turned off and the green light turned on. Unfortunately, the TR 001 would continue to trickle charge batteries as long as they were left in the charger with the green light turned on. Leaving the batteries in the charger for several hours after the green light went on resulted in batteries overcharged to 4.3V.
You can put the overcharged battery into the Sigelei and see if the overvoltage protection will allow you to use it. If it does then use the battery but keep alert for signs of battery overheating and potential failure.
4.3V probably won't kill the battery but it will shorten the battery lifespan if done frequently.
I recommend the four bay Nitecore Intellicharger i-4. It isn't perfect. The sliding battery contacts are a bit balky. However, it does a decent job at charging and stops charging completely after batteries hit 4.2V. I bought one from Amazon for $17 several weeks ago.
Two points:
1. Overcharging batteries is a sure-fire way to reduce their lifespan: Charging Lithium-Ion Batteries
2. I note many have recommended lubricating the screw threads in the Sigelei ZMax telescope section. Noalox is one suitable lubricant since it is conductive. Yet, many have also complained about misfires. May I suggest a better (and cheaper) alternative?
Go down to your local arts and crafts store and buy a 4B (very soft) pencil. The lead in this is good quality graphite which is both highly conductive and an excellent lubricant. Clean and degrease the threaded sections thoroughly with something like alcohol, then let dry. Scribble a generous dirty black mess onto the inner threads of the telescope section from 5mm down (so handling the device doesn't give you dirty fingers) and the screw threads in the battery end-cap. Reassemble the device to grind the graphite into the threads. Give it a quick clean with a damp cloth to remove any excess graphite that may have escaped onto the outer body and you'll probably never misfire again. The only thing to watch out for is to avoid touching the ground-in graphite on the screw threads in future when changing batteries (you'll get dirty fingers!). Safe, non-toxic, long-lasting and effective.
All the best,

Some models come with only 1 cap.I just received my V5 from SweetVapes. I only received one end cap. Aren't there supposed to be two in the package?
My v5 only came with one end cap, if it's the telescopic version, you wouldn't need 2 end caps, as will take 18350 to 18650.
Okay cool, so I shouldn't be worried? I kind of left them a nasty email saying I didn't get both caps in my Sigelei Box.
No you shouldn't, used 18350 battery when 1st got it, but now use 18650 with it.
Guys how would you compare it to the VAMO and the SVD? I am considering buying one of these and I can't decide! I am talking only about the V3 (flat head).
Zmax blows them away in form, function, and durability. Vamo = stripped 510 .. Svd = wonky buttons, giant night stick
Zmax = solid stainless steel all the way through
