Heat killing batteries

[Overlord]

This is something i've been wondering.

We all know that batteries don't like heat or cold. They like to be within a certain temp range.

One thing im wondering cause these batteries that come with kits are not very well made. They seem to loose their capacity fast compared to the other Lithium batteries in other devices.

Most devices I have that use Lithium batteries stay strong for about a year before starting to show performance issues. But 3 batteries in 2 months? Something isn't right.

But today i noticed that with my 510, I was going at it a bit hard and the atomizer got hot ... pretty hot.

I noticed that my battery was hot as well .... not as hot as my atty, but way too hot for my liking.

Do you think that the heat being transferred from the atomizer to the battery might be the cause of batteries dying too young?

That could certainly be a part of it. I think another part of it is that the atomizers put quite a strain on these little batteries. The Lithium batteries in most devices are much better matched in their capacity to duty ratio.

Most lithium battery powered devices don't need a recharge after only a few hours of INTERMITTENT use. I think I read somewhere that the average cig-sized PV would burn for about 5-6 minutes straight before the battery would be depleted if you were to let it burn that long (which I wouldn't recommend). That is a huge burden on these batteries.

Three batteries in 2 months? Wow your burning thru them fast. I have 2 cigs and 3 batteries and they have been going strong for about 4 months now. It may just be the manufacturer of the battery, or maybe your vaping too much too close together not giving the atty time to cool down at all. Also don't charge your battery until it is dead, even though people say that these batteries do not have a "memory", they all seem to no matter what technology of battery it is.

 

[Overlord]

I have to agree CommDown, I think they do have some sort of a memory even if not easily found.

This is why I'm wondering if the 510 PCC might be the cause of such battery problems. Cause i really only used it while at work. I would pull it out, use it for 10ish minutes, then put everything back in the PCC. This would happen like 8ish times while I was out.

When at home, I would use the battery till it died, then use the home charger.

Hmmm ..... PCC doing this perhaps?

The little lithium batteries that come with the various PV's are not meant for what they are being used for. Most Lithium batteries have a max drain rate of 1C or less. So given that you are looking at a battery that should only be drawing .18 amps of current in case of the 510 batteries and .28 amps of current with the 801's. Yet we are subjecting them to a draw of around 1.5 amps of current. This leads to them breaking down rather quickly. Also lithium batteries have a limited recharge capability before they start holding less and less of a charge each time. The avg is around 500 cycles until it gets down to 80% capacity. This is the reason that they don't last in our uses.

Most veteran e cig users have a modded e cig. Myself included.

After multiple hundreds of dollars on Chinese toys, I got a Prodigy.

I am set for a long time... love it.

I'd love to by a prodigy myself just can't afford one right now. I do have one of their PS's though and I love it. For my away from the house use I did a box mod and used a regulator to make it a 5 volt unit.

I'd love a mod myself too but in the same boat as you are rfw2003. Just don't have the $$ right now. Trying to build one myself, but I kinda feel silly using a box mod out in public.

Granted, I also feel goofy using my passthrough in public but at least its not as noticeable. Just using a portable USB charger with it. Seems to last a while.

I was wondering about battery charging in general. I've read in some forums that batteries should be immediately removed from charger after they are fully charged. I've been vaping for over a month now and have been ANALOG free since then. I invested heavily in trying out various models. My model of choice is the 510. Consistent throat hit, tons of vapor every time. I have a PCC for my 510. Great to have if you are a user of 510. So, should I remove my batteries from wall charger right away after charged? Or, is it ok to leave on charger over night even though indicator states battery has been charged.

Thanks,

So, should I remove my batteries from wall charger right away after charged? Or, is it ok to leave on charger over night even though indicator states battery has been charged.

There's been some debate over this, but the bottom line is that these chargers are designed to stop charging when a full charge is detected. These types of batteries are very sensitive to over & under charge.

BUT, being somewhat cheaply made, I think many of us prefer to not take a chance on a malfunction, which of course could result in a fire or explosion of the battery.

So while it should be perfectly safe for the battery to leave it in overnight, it's probably good practice to not do so from a safety perspective, or at least not to make a habit of it.

Kevin,


Thanks for the advice. I really appreciate it.

Well as Kevin said the Charger itself is designed to stop charging the batteries when they reach the correct voltage level. Even the cheaply made one do this accurately as it's a design of the controller chip itself. But if you are still worried about that just make sure you are using protected batteries as they have a circuit of their own that does the same thing. I believe but don't quote me on this that the batteries that come with the PV's are protected as they have much more on the tiny circuit board then just the resistor and led.

I'm not sure if the PV batts contain over-charge protection or not (maybe, maybe not?) but I do know that they contain under-charge protection, which is why they flash when they are low. When they flash they are not completely dead, but low enough to the point that continued use would significantly lower the life of the battery which is why they no longer work after that flash until they are charged again.

I wait until the charger starts to cool-down a little.
Is that the best way to know when the battery is fully charged(cut-off point for the charger)
Seemed to work well for my rn4081s, but not so for my 901s(smaller batts) Then again having a few probs with them at the moment
