First Post. Can I charge a 3.7v battery with a 4.2v charger?

[BobbySkidz]

Hello everyone,

I have a quick question.

First Post. Can I charge a 3.7v(Evod) battery with a 4.2v(Ego Twist) charger?

 

[alee132]

Yes. You can.

 

[BobbySkidz]

Thank You!!

General rule of thumb. NEVER use the wrong charger.
The very fact that you asked the question means that you have no idea what the chemestry of the battery cell is in either the Evod or the twist.

Please be very very careful when it comes to charging your e-cig batteries.
You really don't want to learn the hard way like I did
This was the result of me charging with the wrong charger. So please, just be careful.

I assumed (yes assumed, but now I know) the battery chemistry of the 2 were the same. I know they are Lithium Ion.

I was just unsure as to whether it is safe to charge the 3.7v (Lithium Ion) battery with the 4.2v (Lithium Ion) charger. I know they sell Evod quick chargers (Lithium Ion) that are 4.2 volts. But I was asking to make sure, now I still really don't know.

So, yes, knowing the battery chemistry I still need to ask the question!

Is it safe if both batteries are the same chemistry (Lithium Ion) to charge the 3.7v battery with the 4.2v charger, both being intended for Lithium Ion e cig batteries?

To be sure- call your supplier.

The 3.7 volts is just the nominal voltage for the lithium battery; chargers for them charge up to 4.2 volts.

The 4.2 volt charger is the correct type of charger; but if you look you should also see probably a 420 mA on it; that 420mA charger is the charger for the eGo sized battery which I assume is the case with your EVOD battery.

I don't think there are cigalike sized evod batteries; but if it's one of those small cigalike sized batteries, they take a smaller charger that supplies about 120mA.

 

[dice57]

umm, as long as amp output of the charger doesn't go higher then the max amps the bat can take.

I use the same chargers to charge all my bats, except the 26650 & 26500's, have to use one with large enough bays.

What's the charger's output, and what's the max input your batts can handle? Know these 2 things and you have your answer.

Both chargers are 4.2v. The EGO charger outputs at 420ma and the EVOD charger outputs at 400ma.

I do not know, nor have I yet found, the Max input specs for the Evod 650maH battery I am trying to charge.

Anyone know where to find the input specs for the 650maH Evod battery?

PS- I see many Evod kits being sold with a 4.2v 420ma charger, but mine came with a 400ma charger.

Thanks.

Lithium cobalt, lithium polimer, and lithium manganise are all "lithium ion" batteres. So now, which one are they?
Most Innokin products use a LiPo cell, and most JoyeTeck products do not.

This is why I won't use ANY PV that I can't put my choice of batteries in.

I have a 4.2 charger, but I use a Vision Spinner. Does that mean when I am charging, I set my spin to 4.2 (or as close as possible?)?

I do understand and appreciate your point. Safety First. That is why I am asking.

However, both chargers are 4.2v(one at 420ma and one at 400ma), and if I were to purchase a replacement charger the brands/models reported to work with the charger would include both the batteries in question (and also would most likely be 420ma).
This leaves little doubt in my mind that the specific chemistry of the 2 are close enough for their chargers to be compatible.

I mean, what is the alternative? Throw it away? Are you suggesting that?

There is no easy (or hard maybe) way to find out the specific make up of this Evod 650maH battery. Do you know of such a resource? Please share with me if you do.

I think I just answered my own question.

So, how about this.

Does anyone know of a reason not to use a 420ma charger in place of 400ma charger (both being 4.2v and for use with LiOn batteries)?

Thanks for all the help and advice.

No need, it is designed to bypass the setting while charging.

Hmm.. I'm wondering about that; that's a really interesting question; if the circuitry does what I think it's supposed to do, it shouldn't make a difference, but I suppose different manufacturers are going to do different things and on some batteries you might have to turn it up for it to charge properly; they way it *should* work is once it sees the charging voltage it should turn off the voltage regulation circuitry and switch over to a different charging circuitry.

I fully understand freedom of choice when choosing which products we each use, BUT

This is why I won't use ANY PV that I can't put my choice of batteries in.

And, this is why

Most of the time the consumer has no idea of what battery cell the manufacturer is using in these products.

Yes: 420 is bigger than 400.

You can do it the other way around, no problem, but don't use the higher amp charger on the battery that came with a lower amp charger.


Personally I don't think there'd be an actual problem, but the discrepancy is notable enough to raise an eyebrow.

Setting the spin or voltage has no effect on how the battery is charged, that's up to the battery charger and the internal circuitry of the battery. If you are charging an Ego style battery, a spinner, twist, or standard ego battery, the 420ma/400ma screw on charger is what you need to use (the one you are using now). The light on the charger will turn green when the battery is fully charged.

 

[BobbySkidz]

@TJ99959- Just curious, do you use mechanical mods? What APV do you use?

 

[reron79]

Could be wrong but the maH is just how fast the charger will charge. To be safe, give it a full charge once while you are close and awake. Don't leave it alone!
