When to Change a Battery

[Myrany]

I keep seeing different numbers so I am not 100% sure what is correct.

What I have been doing is changing my 18650 in my REO when I finish one internal bottle of juice (6 mL). So each bottle gets a fresh battery. When the battery is removed the multimeter says it is at 3.2-3.6 volts (varies from change to change a bit).

AM I swapping too early? too late? about right?

I usually feel a significant performance drop between 3.6-3.7 volts and change my battery then.

So you go longer than I would, but I don't think you are going too far. Going under 2.5 volts is the number I've read where you start damaging your battery.

If you don't mind the change in flavor, 3.2 is ok, but very close to the limit so just don't go below that point

Over discharge limit on AW is 2.5V for Panasonic it's 2.6, just stay above 3V and you won't have to worry.

I charge batts when I notice vape performance drop to lower joy level (about 3.6v). My batts last a year or 2 before they don't hold a charge very long.

I'd say that's right on the money.

I never go below 3.2, and switch out in about the same ranges as you.

based on what everyone on ecf says, i gather that overdischarging IMR batteries is at least a little harmful to them and will shorten the useable lifespan of your battery and maybe the performance as far as capacity on a single charge. to put my safety and the longevity of my battery first and foremost i make sure to not drain my aw imr 18650's below 3.2 volts and not charge them beyond 4.1-4.2 Way to go on using your volt meter to be safe! sounds like you got it

Thanks guys it sounds like I am hitting in about the right place for a recharge. That is very reassuring.

I never drain it below 3.6v, sometimes 3.7-3.8 and I change for a new one
