Possibly. Batteries do wear out over time. Seems like batteries for vaping should be designed to get more than 3 months out of them, but vaping can be pretty harsh on batteries (you're basically shorting across the terminals when you fire your mod, so currents can go fairly high, which wears on the battery).

Maybe someone with more specific knowledge of vaping equipment can help clarify.

What mod and batteries are you using specifically (brand and model)? Is it an internal battery mod, or a mod that uses removable external batteries?

Batteries lose their ability to take and hold a charge over time, and lose their ability to hold a charge depending upon how hard they have been used.

There are no 18650 batteries that are specifically designed for vaping. All of them were designed to be used only in battery packs using a BMS (battery management system) for the electric auto industry and portable power tool industry. They were never intended to be used as a single or dual cell use like we use them. The vaping industry has simply borrowed the technology because they are the best option available to us.

It’s prive v8 mod with a Prince tank, removable battery

That basically answers the question, if he's using a mod that uses 18650s. I just did a quick calculation. P = I^2 * R. If you're using a 0.15 ohm coil at 100 watts, that is about 26 AMPS. Finding a handheld battery designed for that seems unlikely. Batteries have an internal resistance and will self-heat, which damages them.

Probably time for a new battery.

That's output current, which is irrelevant to your battery, unless you're using a mechanical or unregulated device where output current is equal to input (drawn from the battery) current.

P also = V * I, which is what's important in a regulated device. Divide your watts setting by the lowest voltage your batteries can reach before cutoff, and you will have the maximum current drawn from your batteries. If you don't know the actual cutoff voltage (and chip efficiency) of your particular device, "three volts under load" is a standard rule of thumb. 100w, divided by 3 volts, equals 33.3 amps. On a dual-cell device, though, you're either looking at 16.6 amps (33.3 divided by two cells if they're in parallel, since the amps are "shared" between cells) or 16.6 amps (100w divided by six volts instead of three if they're in series, since the voltages are combined.) Note, "16.6 amps, or 16.6 amps". The journey is different, but the end result is the same in either case.

That's why I asked the above questions. ;)

Since we now know he's using a regulated mod, we need to find out which battery he is using specifically and then we can determine if there is a more appropriate battery available for the way he wishes to vape. Different models have different battery specifications; most important being the amp rating of the battery.

A 15 amp battery will have a 45 watt limit.
A 20 amp battery will have a 60 watt limit.
A 25 amp battery will have a 75 watt limit.
A 30 amp battery will have a 90 watt limit.

Using a battery at or near its limit will prematurely age the battery so that it can no longer hold or take a charge effectively. That's not even taking into consideration that the rewrap brands exaggerate their amp rating.

Coil resistance is irrelevant if using a regulated mod. What is relevant is the wattage setting used.

Don't forget laptop computers whose battery packs generally use a bank of 18650s.

You are technically correct, the best kind of correct.

Point is that that is still a whole lot of current for a handheld device. Tens of amps at a time are going to be rough on a battery.

I don't recognize that battery "brand", so I have to assume that is a rewrap brand. As far as I am concerned its a unknown battery made by an unknown manufacturer with unknown battery specifications. There is no way to know if it is even the correct chemistry or if it would be safe for vaping.

You definitely need a different battery, preferrably one made by Lg, Samsung, Sanyo, or Sony. What wattage setting do you use?

between here and there
Did you put that wrap on yourself? Unless you know who makes that battery we won't be able to help you figure it out.
Look here for Mooch's testing and battery recommendation.

Guess I am too slow.....lol

It really depends on what kind of battery the OP is using. The ones I use are rated at 20 amps CDR or above. CDR means Continuous Discharge Rate. "Continuous" means "all the time, every time." My understanding is that CDR is a level at which the battery can be used continuously (it's right there in the name) for hundreds of cycles before before any significant deterioration should occur. I don't worry too much about running them at 16A and under. 'Course, if OP has got some 5-7A flashlight cells, that's a different story.

What did it look like before you re-wrapped it with The Flash?

I would interpret continuous to mean the same. That's probably reasonable then. I'm using a mod with an integrated battery at 10 watts. So I can't say I know a whole lot about 18650s. (My experience with batteries is with sizing 125 V banks for backup control power in substations, last one I did was 150 amp hours)

What do you mean, "you don't recognize" the Flash? :D

Seriously if the battery came that way, yeah it is time for a new battery. Using that battery would be like buying gas for your car at a place called "It Might be Gas" with a "?" on the octane sticker on the pumps.

Only for curiosity's sake, where did you purchase it?

If a vape shop, never buy batteries from them again. Use a trusted online battery supplier instead:

North America
www.liionwholesale.com
www.imrbatteries.com
www.illumn.com
www.rtdvapor.com
www.batterybro.com
www.orbtronic.com
UK
myepack.co.uk
www.batteriesplus.co.uk
www.fogstar.co.uk
www.nkon.nl
Welcome to Ecolux. The UK's Battery and accessory specialists. Wide range of authentic leading brands in stock ready for immediate dispatch.

Getting information from this guy is like pulling teeth. :facepalm:
