Should I be concerned about my battery/charger??

[dw'struth]

I have noticed recently that my MNKE 18650 has charged all the way up to 4.3 volts, according to my Vamo anyway. Should this prompt any action such as seeking a new charger? At first, I thought, "Ah, no big deal." But I want to make sure......

As always....Thanks!

Is that right after charge or after a "rest"? Some sites state that IMR should never go beyond 4.29.

Orbtronics has 4.29 as max for Panny CH.

Orbtronic - Panasonic CGR18650CH With Top Button, 2250mAh IMR High Drain 18650 Battery Cell-Made in Japan

RTD Vapor has 4.2 with a +- of .5 which would be 4.7.

If it was me... I would buy another. It is kinda borderline.. and not sure I would go through the worries of "what if".

It might be time to seek out another means of a voltage reader, the Vamo isn't exactly very precise, get yourself a multimeter.

you left out the most important piece of inf... which charger are you using?

I have two Nitecore i2 and never saw anything above 4.2 and that number drops to 4.1 after one or two draws.

I agree use a voltmeter once the battery is fully charged. Heck you can take it to a auto parts dealer and they can check it or Radio Shack. Overcharging a battery is never a good idea.

Need to know what kind of charger that is.

The battery should be allowed to rest for at least 30 minutes after charging. The Vamo should read a properly charged, properly rested battery at 4.1v.

May i ask if 30 minutes rest following a charge is also recommended for say a innokin VV or MVP?

A rest period after a charge is recommended for all batteries, doesn't matter what device you use.

Yep.

I also concur with the recommendation of getting a multimeter. They have multiple useful purposes around the house in addition to their usefulness in checking voltage, current and resistance in our devices.

A good one can be had from any of the big box stores and auto parts stores from ~$20.00. It's a great investment.

Ok, I have a nitecore 2 charger. I have heard about resting the batteries. However, I probably (I know I did) popped it into the Vamo right after charging. I don't even use the Vamo lately, but just used it to check voltage before putting it into my mechanical.

Next time I charge, I will be sure to rest before checking said charge. Thanks.

The MVP is excluded, mainly because it can be used as a passthru while it is being charged.

you can and do get some whacked readings from a battery fresh off the charger sometimes, because the internals are still stressing and relaxing after having a bunch of energy shoved into them. I would say take the battery and let it rest for a bit then read it again to be sure it is what it says.

The Vamo is accurate to within 0.1v when reading battery charge and 0.1 Ohms when reading resistance. If you popped the battery right into the mod straight off of the charger, then you could have gotten a 4.3v reading when the actual voltage was 4.2v.

I would still get a multimeter. And I would be religious about resting those cells after coming off of the charger. If you continue to get high voltage readings after charging, then maybe a good charger has gone bad and needs replacing. The battery, too. Continued overcharging will seriously shorten the life of the cell and could cause an accident no one here wants to have happen.

After this evening's charging, and a good rest, it showed 4.2 on my Vamo and my voltage checker. I think that I am in the clear for now. Thank you...

 

[Scarey]

My i2 has never gone over 4.22V. I think the variance in your Vamo is messing with you. Get a multimeter.

I am always learning something new here!
I never knew a charged battery needed a rest. Thanks for the MVP2 exception, I was wondering since it can be used while charging. I do regularly charge batteries for other uses and will now make sure they get their rest first before using.
