These are the 2 items im looking at. But when i looked at the battery info, and the battery rated voltage was 3.7V. And then i checked the charger, and the output was 4.2V, and i wanted to know that do these 2 work together, because i checked 5 chargers and they all had the 4.2V output.

tl;dr Does a 4,2V output charger work on a 3.7V rated voltage battery

yes 3.7 volt lithium batteries are charged at 4.2 volts. A fully charged battery will read 4.2 volts but soon drop to 3.7 volts as it is used. 3.7 volts is it's nominal voltage while being used.

Thank you. That helped a lot <3

You do understand those batteries are protected with a 5.2a CDR, right?
And the pcb doesn't trip until 7.2 - 8ish amps.
They wouldn't be of much use for vaping.

PCB?

Printed
Circuit
Board.

These are not the correct batteries for vaping. They have a built in fuse and the amperage is not high enough

Look at lg he
Or Samsung 25r instead

Those appear to be protected ICR chemistry batteries. They're not high drain or safe chemistry. They are obsolete for use in vaporizers. Not recommended.

You want IMR chemistry batteries. These are unprotected, high drain, safe chemistry, and high amp output, like below. Pay particular attention to brand and model numbers. I also recommend purchasing only from reputable battery vendors like RTD Vapor, Illumn, Lighthound, or Orbtronics.

Battery Basics for Mods: IMR or Protected ICR?

Deeper Understanding of Mod Batteries

Ahh Printed circuit board. Yes another issue is the length is longer with the protect button on the top. They can be used for vaping if your mod will accept the longer length and you stay below the trip amperage for the protect button. The protect button resets with connection to a charger if you trip it, at least all I have seen do. They are safer for vaping than an ICR one with no protection.
However IMR batteries are recommended for vaping. Safer.

Not only are those batteries totally unsuitable for vaping, I wouldn't trust that charger with some rechargeable AA's, let alone a high-drain 18650.

You're better off with one of the following:
Sony VTC4
Sony VTC5
LG HE2
LG HE4
Samsung 25R

Just to name a few...

The charger, like nyiddle said, not a good choice. Check out the Nitecore I2.
Without info on what your mod is and what resistance you run in your atomizer recommending a battery other than the one you are interested in can't be done beyond what GrandSam recommends. The 'right' battery would be capable of providing approximately twice the amps that your setup requires.
