Just wondering how long they last till they need to be replaced. And what to look for when they begin to fail.
Thanks a lot.

Since they need to be charged every day, about 2 1/2 to 3 months??
I may be wrong but I thought I read somewhere that they have up to a 1000 times recharge capability.
NOTE: I just checked a few websites and they say >500 cycles.

No battery expert, but most of the stuff I have read says they take about 400 cycles. Roughly a year +/- depending on your style... Mine are 3 months old and show no signs of wear. A good charger is key to success with IMR batteries, I use a xtar WP2 II and it charges them to 4.18 just below the full capacity threshold that will in theory lengthen the life of the cells.
I use a Pila charger... I just noticed that after 3 months or so that they dont have as much holding capacity as when new... Thats when I replace them....
I have a Tenergy TN270 charger that was sent with my Provari.
I don't let the batteries run all the way down before I recharge because I have 2 of them. I usually charge one while I use the other one.

The tenergy will do just fine, just make sure to pull them off the charger when the light goes green. Don't charge overnight as the tenergy will trickle charge the cell; meaning there is a possibility of overcharge. Overcharging a IMR battery will reduce the cells lifespan and severely overcharging it can cause it to vent. This is why a Pila or Xtar charger is nice because when the battery is full they do not trickle charge the cells so there is little chance at overcharging the cells.
As long as they are treated well should last at least a year being cycled every day in my experience. Yes they will loose some capacity over time but they shouldn't in 3 months. When mine loose 15-20% capacity is when I toss them since they degrade quickly at that point.
Are you sure about the Tenergy?
"Indicator lights alert you when the battery is charging or fully charged and it will auto-shutoff after charging is complete, so the batteries will not over-charge."
I got six of them to keep in rotation. I'm getting just under 24 hours on one charge, so I've got a while before I hit 500 charges on a single battery. Good.
Anything to do to extend it. Like keeping out of the cold, running down all the way before recharging, clean charger, run my Provari on lower voltages etc.....??
Also., is this Tenergy charger auto shut off when it's charged?
Thx

I suspect that the tenergy charger, like many 'smart' chargers, poll the battery at intervals, and decide whether or not to supply current based on what the battery is reading at that time. Once it detects the battery is charged, it stops. However, there is slight leakage over time, and it will eventually trigger again. I doubt that would happen overnight though, unless your cell is bad/old. Perhaps that is the concern?
Rotating 2 sets for 9 months now and staring to lose a lil zip but still working. Running at about 80% of original state.
The Pila is the only charger id trust to cut off at full charge . Most still trickle charge after the light goes green.
As for the 2000mah 18650 ,you would be better off with the 1600mah 18650.Battery life/performance is better then the 2000 actually from what i read.

#1: Don't Use A Cheap Charger.
The Pila has been thoroughly proven to be the best cradle charger for Li-Ion batteries, can't beat it with a stick. I did much research on the CandlePower forum before I bought mine.
ProVape sells them for $45.00, seems like a fair price, I payed much more over a year ago.
Mine charges to 4.15v and then stops charging with NO trickle (very important).
Just buy the Pila and forget about any charging issues.
Its just the right thing to do.
You'll thank me in the morning.

Tenergy is an ok charger. I wouldnt worry at all using it and also your batt will probably stay good for a year at which point it will not hold as much of a charge as it does now that it is new.
I would replace all my batts once a year if I were you. They dont cost much. So dont worry about it. Use them as long as they perform. I have used a tr001 trustfire charger for 3 years and I still have some IMR 18650's that are almost 2 years old now and still going..
The tf and tenergy charges arnt complete pieces of crap but id still put them in the cheap charger catagory. It doesnt compete with a Pila imo.
