Testing ecig batteries

[mikeprice]

Hi all

Mrs mikeprice uses those vape things.

Clearly they use a small li battery to vaporise the fluid and they 'wear out'

 

Now - she is saying that she has some that are getting low on power and some that are starting to head that way so I though I would try testing them to see what is what

 

There is a clear terminal at the bottom of the screw thread - and the barrel acts as the other terminal

so I connected a multi-meter to both and tested it

 

go a reading of 3.5 - 3.6 V of the ones that are one their way out

 

 

and a LOWER voltage from the ones that are working fine

 

which seems strange to me

 

anyone any idea what is happening?

It's going to be the current draw that's important here, not the voltage.

 

It sounds like you are using the ce4 style batteries, they are quite cheap and cheerful, I'd look for something that uses 18650 cells, you can get a much more robust battery then, and it will probably outlast all the others combined!

I recently picked up some of these

I don't run higher than 20W so the current is fine, they last a good while being 300mAh

How does that battery connect to the ecig tank and element section?

 

Is there a container that will replace the one that she normally uses - which is sealed?

 

Thanks

The battery pack (Mod) I'm using, has a door to remove the batteries to put hem in a charger. https://www.vapeclub.co.uk/vape-mods/geekvape/aegis-legend-200w

 

The tank (bit with the coil and the bit you put juice in) screws into that.

Interesting article here about using vape batteries for drones in Ukraine. Don't be getting any ideas @mikeprice ....

If its an 18650 battery then the voltage range should be from about 2.5v to 4.2volts.

 

4.2 being 100%.

 

Something like this can charge them

I agree with the idea of using better cells

 

However, the batteries that fit her ecig do not mention which type of cells are in the sealed unit that we buy

 

She only wants ones that are tubes about as thick as an AA battery so that limits what I can get for her

To test the health of a battery you need to measure its internal resistance, not voltage, you can do this by measuring its voltage and then measuring it again under a controlled load. Internal resistance also changes as the voltage of the battery drops so make sure you test them all at the same voltage to start with. https://learn.sparkfun.com/tutorials/measuring-internal-resistance-of-batteries/internal-resistance

 

21700 Cells are much better for high loads, I use the Molicel ones in my electric Mountain board.

I might be stating the obvious but I have found that charging the non removal batteries using a higher rated usb adapter will degrade the batteries a lot quicker. Same goes for the 18650's in a charger.

Those devices with non removable batteries only last a year or so at best in my opinion if you are a heavy vaper.

 

If you do go for a new device with removable batteries, please watch out for dodgy battery makers. My preference would be to buy these from a shop as opposed to online.

Not charging your device or batteries overnight also helps extend battery life and prevent a fire risk.

Regards not buying online, all of the below websites are safe to buy from and more than likely supply any shop you might use if they have good cells
