Confused. Why would it be 4.2/4.1ish if it's a 3.7v battery? I'm going to get a nicer charger soon, that does provide this information.
A fresh battery is 4.1 to 4.2. 3.7 is the average through the charge cycle. You are good.

Also, if you have a voltmeter NOT part of a mod, i.e. a DMM, check the battery voltage right after charging and then again a few hours later. Should be 4.2/4.1 right off charge and stay there. If it doesn't, likely just time to recycle and replace.

Or get a charger that shows a digital readout of the actual voltage of the battery.

Give it a cleaning ... and in particularly take the spring out of the cap and give it a stretch ... more than you think it needs. The spring pressure is the most common probably for low batt readings.

Just did the cleaning - put my not-as-nice-as-I-thought-it-was-battery in - 99% battery remaining :)

Don't really know what that means, lol! :D

As long as you're not vaping at .2 ohms or 150 watts, the battery is fine. It's those idiot cloud chasers who really have to worry about how many amps their batteries can deliver -- us tootle puffers are generally only dragging 5 amps or less. :) (my present 2.1 ohm coil and 9w setting is dragging a blistering 2.07 amps!)

I have no clue why they use "I" or "current" to describe it, because it is amperage; I suspect it's because of some weirdness in the french language, which is what makes Ohm's Law so utterly mystifying -- they use "I" instead of "A". They also use "R" instead of "O" for ohms, but that is a little better, because "R" stands for "resistance," which is what ohms measure.

Oui oui, ma petite chica-D... eeeeeees vraiment non veirdahness eeen la lange du Francais.

In 1820, the French mathematician, André-Marie Ampère developed a theory and had it published. In the publication he used "I" for "intensité de current" (translates as intensity of current). The symbol for the intensity of current (now just called current in English) has been "I" ever since.

The units for current are called amperes (or just amps for short). One ampere is equivalent to one coulomb of charge per second.

One more question - I bought this Provari P3 + 2 Nauti tanks off of eBay for $75.

I notice when I put my "fully charged" batteries in it that they are neither of them at 100% according to the Provari.

I have an older (2 years) 18650 Kamry 2100mah that starts at 73%
and
a 3-week old Imren 18650 3000mah 3.7v 40A high drain that starts at 91%

What's up with that?

hejira, have a look-sie.

It's VapersTek -- sorry!

I use WTA -- I *have* found a link for a way to make it, but if I don't have to, I'd really rather not! The stuff you buy is a lot more refined and purified -- the best possible place to buy it is 15ml WholeCig WTA e-Liquid -- very good stuff, very pure, and a LOT less costly than a nearly identical product from aroma.

Andria
Man. I should have asked you where to buy it. Been buying from aroma.

Means you're getting better connectivity ... most likey it was stretching the spring that helped the most. Also - note, the P3 batt gauge doesn't indicate the 'charge' in the batt. It's more like the gas gauge on your car showing the estimated miles you can travel based on gas consumption. Jump over to Provari forum area to learn more.

A fresh battery is 4.1 to 4.2. 3.7 is the average through the charge cycle. You are good.

Yep, that, and that slight variations in meter calibration, test lead resistance and such can throw the reading off.

Along with differences in chargers, their adjustments for cut-off voltage...

So if a given set-up of equipment gives you, say, 4.1 volts consistently at the end of the charge, no problem. Consistent good readings are desired. If an hour later that same equipment show 3.8, the battery isn't keeping the charge.
