I was told by a rep at V2 that their batteries were a lithium battery.Then I asked about the best way to charge, whether to let run down completely and was told PROBABLY the best was to let it run down completely !
From what I have read here the best way is to charge it(because it is a lithium battery)is to charge it BEFORE IT GOES DOWN COMPLETELY,RIGHT ?
also curious as to whetehr the Volt x2 is a lithium battery or not ??
Thanks
Craig

Here are Two "Rules of Thumb"...

1) If you Can't Remove the Battery from your PV, like an eGo or a KR808, it's a Li-Ion 99% of the Time. Charge Often and don't let it go All the Way Down Unless you have to.

2) Sales Reps are Usually the Least Knowable People to talk to. Unless you want to buy Something from them. Then they have ALL the Answers.

The low voltage cutout on most commercial e-cigs is well above the minimum voltage (0% state of charge) for lithium polymer batteries. So you are never actually getting to 100% discharge.

My $.02... For e-cig use, there are other factors that will affect the life of a battery that are far more harmful than depth of discharge. Seeing the most e-cigs have a high cutout in the first place, any additional precautions are going to be past the point of diminishing returns when you look at the other stresses that we put these things through.

I think you will find that most Modern battery operated devices have some manor of Low Voltage Cut-Off Circuitry.


I’ll will be more Clear.

All other Factors aside. A Li-Ion e-Cigarette Battery will, on Average, have a longer Lifespan if a User does Not Repeatedly Drain the Battery to the Low Voltage Cut-Off Threshold of their PV.

I fly electric powered radio control model airplanes which use lithium polymer batteries (very similar chemistry to the lithium ion batts in PV's). These battery packs are a lot more expensive than the cells we use in our PV's and I did a lot of research on them when I got into the hobby. LiPo batteries can also be considered more dangerous than Lion batts in PV's, so that was a factor also. FWIW, I agree totally with zoiDman and DC2. The link to the battery university in post #7 is spot on as far as I know.

The other point about the charge cycle of lithium batts is that you also stress them if you charge to 4.2 V per cell. On DC2's linked page you will see the effects of charge voltage to longevity in Table 4. I know our chargers are not capable of limiting this, but thought I would mention it anyway. Length of time spent at full voltage is important too. I do not charge a battery and leave it that way for longer than I have to. HTH.

Your statement is true, all other factors aside. But unless someone only vapes in a controlled environment, all other factors are not aside. That was my point; considering all other factors, it is not (IMO) worth worrying about when to charge the battery. If the low voltage cutout was closer to the minimum safe voltage for the battery then it would be worth thinking about. By Cadex's estimates, we are already at roughly 1000 charge cycles just with the buffer of a high cutout. For the average vaper, 1000 charges on an 1000mAh eGo bat would be 2-3 years. How many batteries will make it that long without non battery related failure? I really don't know, but I assume not too many would make it by the amount of "my X month old eGo died" type threads.

If you can't replace the battery without surgery, chances are it is a Li-Poly. eGo, kGo, Riva, Volt X2, 510, 808, ect, ect... All use lithium polymer.

Additional related question- Is it bad to vape it while its charging?
Some e-cigs are what is called "pass-throughs", they are designed to vape while hooked up to power. I believe the Volt X2 is advertised as both a pass-though and a chargeable e-cig battery. Go to Smokeless Image's web site and see. They also have some videos and directions for some of their other products.

No idea about the v2, have you looked at their website?

There is an ECF thread on battery safety, some batteries should "rest" after charging. And, oddly, larger batteries are supposedly safer than small ones.

What other factors you are considering Raider?

As far as I know, all these devices use lithium ion batteries. Please correct me if I'm wrong.

I agree 100%.

The battery suggestions about not completely discharging them are meant for batteries that do not have electronics to limit their low voltage cut-off and full charge voltage. If it has a light that blinks and automatically cuts off, then it is preventing the battery from completely discharging to a damaging level.

As far as I know, all these devices use lithium ion batteries. Please correct me if I'm wrong.
High voltage ( as you mentioned): time spent at >4.1v. This if for the charge overnight crowd.
Tempurature: big battery killer and dangerous to the user if gone to far.
Amperage: completely dependent on the type and size of battery, but many common devices are pushing the limit.

You're right, lithium ion. I had a CRS moment there for a bit.
