Coolfire tc100 battery

[Simm555]

Hi fellow vapers
I have just purchased the coolfire 4 tc 100
Gave it a good charge and after taking about 5 drags on it the battery drops by about a quarter !! Surely this shouldn't be happening, maybe a faulty battery ? Expected great battery life from a 3300 mah battery. Anyone else noticed this ?

The battery is inbuilt, yes? The battery meter on mods is normally useless.... dropping by a quarter means nothing, it just means it's not fully charged anymore.
My newest mod drops to 4/5 'bars' immediately. Only a full run from start to finish will tell you how the life is.

If you turn it off does it have a charging indicator? If so, maybe wait for that to disappear. Don't go by the battery level just showing full bars.

Some times the first bar on a mod goes away quickly when it drops down from 4.2V to a stable 3.7V. Then it stays there most of the time and the last bar goes quickly also.

3300 is actually not "large" at all, any wattage usage over 10-15W will be fairly hard on it, so it's completely normal.

When you consider that a replaceable 18650 mod is dependent on the battery's capacity which is usually 2500 or 3000 mah,and with a single battery mod, it's easy to kill it within an hour or two (a "regular/medium to heavy" vaper will have to switch the battery about 4-5 times a day in such a mod), I would say that yup, it's very easy to see the drop after just a few uses.

I know that I (and many others have also) switched to a dual battery (and replaceable type) because the pull on a dual (and I prefer a parallel) is much less harsh on the battery so where a single battery mod would last barely an hour's worth of usage, a dual will/can last most of the day.

All my old sealed mods (probably similar mah) are only used at home for my drippers or are just sitting there as they don't push higher than 40W (while my single 18650 battery ones are at least usable being 60-75 Watts, still don't last very long, but at least they are for home usage and I just switch the batteries when needed).

Sounds like a faulty unit, then again could be normal for coolfire. Might want to give your local B&M vape store a visit or get in touch with the factory. My Eleaf Istick 30 shows full charge after 1/2 an hour of vaping (2200 mAh).
