When does a battery

[Butters78]

cut off usually? As in aw imr. I noticed that when my provari said my battery was dead it was 3.8. I thought the aw imr cutting off at something like 3.2. Oh and notice when the provari says it is dead and I take the battery out and put it in it starts working again. Odd.

I don't have a provari, but I think it depends on what you have on for an atty resistance wise and the watts. The voltage of the battery is only part of the equation. It may be shutting down because at 3.8 Volts it can't give you the dialed in watts.

Hopefully someone with a provari will come along.

My mini starts flashing at 3.2 volts with the AW 18490, but I've noticed that the battery's voltage seems to "rebound" after a short period of rest.

When they flash I remove them though.

3.2 with a load or without? Mine is 3.7 without.

3.2 with heavy use.

3.2 with heavy use.

With load I meant with an atty attached aka under load.

 

[Underwhelmed]

Yeah with an atty attached.

Mine fires when I check the battery voltage or ohms, so I always have an atty on there. Sometimes it seems like the best vape is when I check the volts/ohms, lol.

Are your batteries getting some age on them? I think the resistance changes as they get older.

I'm not battery guru, but remember someone mentioning the crystallization a battery gets as it gets older.

you can unscrew the bottom of the provari, pop the battery out for a couple of seconds and put it back in. Sometimes you can get an extra 10 minutes of use this way.

Has it / does it always do this? Could have been a fluke in the electronics. Had that happen once or twice with other devices.

Mine will start giving me the low battery warning. I'll ignore it for a bit. Goes away all on its own. Its been tripping me out.

I'm not sure if my positive contact is getting a bit dirty and that is causing it. Generally when I check Cb at this point it'll tell me 3.5-3.7 yet its still saying the battery voltage is low.

Some where after it starts to blink but before it is truly dead, I swap it out for a charged one.

At first I thought the Vari was reading incorrectly then figured it had to be the difference between underload (in the provari) and resting (with the multimeter). Multimeter has always told me 3.7 - 3.8 when the Vari says its dead.

Every Provari Ive ever owned has done this.

Dirty Contacts.

Dirty Contacts.

Good thinking.

I've owned the provari since January and never cleaned the battery contact. I used a qtip and some isopropyl and there was some black stuff on there. Thanks boss.

Mine are getting pretty old. I got the provari back in January. Right now I'm debating on getting the extention cap and 18650's.

I have the 18650s, and they are almost 1 year old, Provari quits consistently at 3.2v. If a newer batt or cleaning the batt terminal doesn't solve the problem, I'd contact Provape.

Thanks boss. I think part of it is that I've been checking it without a load. Hopefully it will say 3.2 with an atty on it.

Hmmm.. I don't own a provari, so I don't know the voltage they shut off at, but on my ZMax it cuts off after being at 3.4 for a few hits. 3.8 seems like a high shutoff since they only charge to 4.2V right?

The provari flashes slow to let you know the battery is starting to get low, then it will stop flashing for a bit, then it will flash fast to let you know that the battery is about to die.

It cuts off before the battery has nothing left in it to save you from ruining your batteries. If you are running a mechanical mod you should change your batteries before they die.

Seems like quite a difference, even if not under load. 3.8 and then reading 3.2 under load? I'd suggest the same as others - a clean, and if that doesn't work then contact the vendor.
If a battery measures 3.8 on your multi-meter it shouldn't be dropping to the cut off low volts on your device.

I cleaned it and right now it's reading 3.9 without a load and 3.6 with. So hopefully that was the problem. These batteries will be a year old next month so I'm going to order some new ones soon.
