battery discharge limit question

[vapero]

I know I should watch the battery bolts carefully in a mech to prevent over-discharge but where is over discharge set really?
I tent to get my bats out at about 3.6V but could I squeeze a few decimals out? what's the optimal time to change a bat? besides the quality of vape (that's pretty tangible and easy to spot) but will I get more charge cycles if I take them out at 3.8 than at 3.4? please illustrate me!

The more you deep cycle your batteries the less life you will get from them, meaning 3.4-3.2v. If you pull them out and charge them around thge 3.5-3.6v mark the longer they will last.
Technically they are good down to the 3.3-3.2v mark, if you want to get specific about it, but if you can keep them charged up on the higher end, it's better for them, as well as a better vape for you!

That's depending on the battery, it varies. Most IMR batteries may go down to less than 3V before getting permanent damage, but I'd not recommend going that low.

Generally speaking, 3.2V is considered the lowest safe voltage to bring a battery down to.

But on a mech the only interesting voltage range goes from fully charged to approx 3.7/3.6V in fact, so I'd not see much of a point in going lower than that.

If you really want to (safely) squeeze the juice out of your batteries get a regulated mod. But it's a different vaping style..

Li batteries are rated to 2.5v discharge any lower they will become damaged. I really really doubt anyone could vape them this low and not notice the difference.

taking them out earlier rather then later is called a short charge and will extend the batteries overall life, but seeing how the average Li batteries are rated for 300 to 400 (full) charge cycles, running a few in rotation will get you well over a year in any case

Thanks I think I got it! I usually have a few fully charged around and can swap them without a hassle I just wanted to know on the long run what pattern will make them last longer. I could se myself vaping up to 3.4 when I'm out and forgot to change them but I do change them much more often

Heck, it won't even produce vapor that low ... so you'll definitely notice.
I know personally, I've ran my down until it basically wouldn't fire. Voltage comes out to 2.8volts almost every time. Which as mentioned, is above the safe discharge limit.


Whether you charge them at 3.2 volts or 4.0 volts will have no bearing on how long the battery lasts. The chemistry in the battery will erode over time, regardless of what voltage you charge them at.

Teehe,
I used one of my MNKE batts so low that I couldn't even check it battery life on my VAMO later that day...

I agree. However, I have to be careful when I've just replaced the wick in my AGA-T. I don't notice the vape deteriorate until the battery is below 3 volts. Took a batt down to 2.7 volts once because of this. I'm more careful now.
