Trying to figure out battery life with different clearomizers.

Tabacso

What determines the drain on the battery ? Is it the voltage or the wattage?

For example I have my istick set at 7watts.

When I stick a 1.2 Clearo on it, the voltage is 2.91v

When I stick a 1.5 Clearo on it, the voltage is 3.57v

Which one will drain the battery quicker?

This is a totally n00b question I know.

Thanks!

the lower the Ohm reading the higher the drain on the battery, therefore therefore

1.2 clearo will use more battery than a 1.5 -

I thought that only applied to unregulated batteries where you can't choose wattage / voltage?

I just can't wrap it around my head.

The 1.2 coil uses only 2.91v

The 1.5 coil uses 3.57v

Yet the 1.2 coil depletes the battery quicker.

Yup, according to ohms law the lower the resistance the higher the voltage/current.
Or something.

That's only with non-regulated batteries. Like those competition mech mods etc.

I thought I knew what i was talking about until i read this, Now i dunno anymore.

Cheeze.

This is what the math says:

>>When I stick a 1.2 Clearo on it, the voltage is 2.91v

2.91v x 2.91v = 8.4681 / 1.2ohm = 7.05675 watts

>>When I stick a 1.5 Clearo on it, the voltage is 3.57v

3.57v x 3.57v = 12.7449 / 1.5ohm = 8.4966 watts

If you are setting the watts on the device to 7 for both those coils then the real value for them would be:

1.2 Clearo = 1.209728571428571
1.5 Clearo = 1.8207

Which is using more power?

The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):

I(A) = P(W) / V(V)

1.2 Clearo = 7 watt / 2.91v = 2.405498281786942 amps
1.5 Clearo = 7 watt / 3.57v = 1.96078431372549 amps

So finally - your 1.2 clearo is using more battery.

Thanks. Makes sense now.

I made a mistake in my previous post.

My 1.5 clearo is actually 1.8ohm.

Your calculations still make sense though as I had the correct voltages.

1.2 Clearo = 7 watt / 2.91v = 2.405 amps

1.8 Clearo = 7 watt / 3.56v = 1.966 amps.


Anyway, I now have another reason to hate how vaping is moving away from regular resistances to super low resistances. I can't get anything over 1.2 for my new shiny Eleaf GS-Tank and I hate it.

This is definitely linked to my TC40w Rant thread from a few days ago. I noticed that my battery lasted feck all with my low resistance clearo on it. Even though I was vaping at the same wattage and LOWER voltage. I couldn't figure it out. Hence this new thread about which clearos affect battery drain.

If I used to 0.2 coils that came with my clearo the battery would barely last a day.

Watts are a bigger drain(bigger indicator) on a battery than anything else.
The higher the wattage the bigger drain on the battery.Hnce your ESB bill coming in kilo watt hours.

Forget about amps,voltage (well not forget about them) but if you know your watts you`ll know how much drain is on your battery.

But they're both at 7 watts. And the 1.2clearo @ 7watts causes faster battery drain. So it can't just be the watts.

Ok that's the way I was always thought it--not vaping related though and Im still learning these things.

A 0.5ohm coil at 4V and 32W should use the same amount from your battery as a 1 ohm coil at 6V and 32W

But if you use a higher resistance coil at lower wattages then yes your battery would last longer.

So basically get a higher resistance coil and use it at lower wattage.

Btw Ive only started on sub ohm vaping so Ill let you know in afew days if it holds up.

I used to vape a 1.2 coil @ around 12-14 watts--4-4.5 volts
Im vaping a .6 ohm now at 13 watts. 2.7 volts.

If it hold true my battery should last the same amount of time between charges.

I should have added, and as Hellrazer has stated, that watts = power consumed.

But but but when it comes to batteries it's amps that matter and on top of that the efficiency of the battery itself.

You see batteries are rated in amp hours meaning that they will produce X amps for N time.

Batteries also consume themselves as they provide power and a higher draw (amps) as created through chemical reaction in the battery causes a certain amount of energy to be wasted as heat. The efficiency of a battery will vary based on the amps not watts consumed by a device.
