14500s charging faster than usual

[KiloWatts]

I've noticed that my 14500s are charging insanely fast these days. It usually takes 20-30 minutes for them to reach full charge now. I make sure to put them back on the charger as soon as my vape drops off in intensity, so it might be that. But is a faster charge time indicative of anything in particular? (batteries aging?)

The Q should be how long are they lasting between charges? A battery as it ages will charge quicker than when new but won't last as long and that is the indication ya need more batteries. If you have an MM you can check their charge state when they come off the charger.

And what charger are you using, 20-30 minutes seems awfully fast.

I'm using this charger:

Specs are:

This is a very nice corded charger that also comes with car adapter and plug. Has a switch that allows you to change the max charge from 3.6v to 4.2v.
Has two independent charging channels for Li-Ion batteries but will now also charge Ni-MH and Ni-CD 1.2 volt batteries.

750 ma output at 1.2 volts and 650 ma output at 4.2 volts, charges batteries fast.

Smart electronics chooses the fastest charging method based on the inserted batteries.

The batteries definitely aren't lasting as long, but I don't know if that's because they're aging, or because they're not being charged correctly.

Both! What is the resistance of the atties you are using on them and how long does a batt last? In order to help we need more specifics, so spill the beans

@ 650mA it should take roughly 1.5-2 hrs to charge.

Well, I'm using 1.5ohm atties, and the batteries last maybe 4 hours at max.

Here's the thing - the charger is totally chinese so I don't have a big idea of what's going on. There's a switch to choose between 3.6V and 4.2V. I leave it on 4.2V, because it never seemed to finish when it was on 3.6V.

Here's the "manual" for the charger:

I don't have a multimeter, so I'm in the dark.

Now that I think about it, I have been charging the batteries on the 2nd terminal, instead of the 1st as recommended. I wonder if that has anything to do with it.

It shouldn't. If you are going to vape LR get yourself some IMR batts they will last longer You might have stressed your battery some and the rock content of the battery may be excessive. Rock content is spent chemistry that can no longer take a charge,

Your cells are just wearing out and you are experiencing a combination of reduced capacity and increased cell resistance (reduced performance) as a result.

For the record, a 1.5Ohm load on a LiCo chemistry 14500 is over the maximum discharge rating of the cell and will wear it out quickly. For those loads, you would be better off with IMR14500s. They will also wear out, but they are safer at these loads, and will maintain performance as they age a little better.

a battery is a battery. The charger is what makes the difference. Your experience with other cells and chargers is what?
