Is there any charger that is built with a tester in it, something that tells what the battery is coming off a full charge? If there is I want one

Now that would be a good prodcut to make and sell for vapers. bnrkI was away from here for about a year. What happened to the "Signatures"? I can't seem to edit mine to include a battery safety statement.
I think a Battery Safety Banner members could include in their signature would get the word out around the forum more than threads that may never be seen, like this one that is under "Media & News".

I was thinking about that this morning. A charger with a built in meter. I imagine the Chinese are working on it as we speak.
I think the suggestions of checking voltage before and after charging and logging the results are like buying a new car and having to check the oil every time you turn it on or off.
I saw the internal resistance test information and thought it was good. I had never seen that test procedure and thought that it was something only labs with expensive equipment could do. Even with that information, consumers are probably 90% ignorant of how to do that or what it means. For all they know, Ohm's law applies to transcendental meditation. So, we still are back to the question of how a typical consumer, who doesn't know a watt from an amp and has never found a need to buy a voltmeter, processes this information to decide what's safe and what's not.
I think that in the future, electronics will protect us from ourselves. Inside that, I think smart chips in ecigs will detect signs of failing or potentially unsafe batteries and warn us on a display that the battery has reached end of life for whatever reason it detects. It might be gases venting slowly from the end cap or signs of internal resistance building or a 30% rise in battery heat inside the mod. The only sure way to protect the consumer is to make the device itself safe to use. We are still sort of in the hobby stage of ecigs, low in the technology curve of a product that hasn't reached maturation.
Until then, we depend on vendors to supply us with relatively safe batteries and information on what battery to use and why the wrong battery is unsafe. Aside from that, there are cheap batteries that didn't pass QC test available from many sources, although you never know why they are a few dollars cheaper. We are a Walmart low price generation, but we still expect low price goods to be safe enough to consume without danger.

Excellent idea- here is the link everyone needs- http://www.e-cigarette-forum.com/fo...9007-warning-rechargeable-batteries-mods.html
Thats a whole different point, I was only trying to let you know about your first question DaveP about checking the internal resistance,,,, by the way you can use your Atomizer as the resistor since you can check and know the ohms of your Atty
there actually is a new technology meter out there that can also check the internal resistance of a Battery, but not the ones we use yet I believe , this = Battery charger and battery analyzer experts - Cadex Electronics Inc.
The reality is the "business" of e-cigs is driving the market today.A marketer once told me that if I could PROVE what I was suggesting
would increase sales...He would be all ears.

Good idea about using the atty coil for a load resistor. I was just daydreaming about the future of batteries. Where there is a problem, someone will eventually invent a process to eliminate it.
It is mind boggling there is much out there! Glad I am not a newb wading thro all this, whew, it is even more saturated than when I started! bnrk
I couldn't get the signature to accept the link you suggested, so I'm going with this for now. Until someone comes up with something better.
I've started a thread in the Campaigning discussions sub-forum with a summary of the items I mentioned in the post:
http://www.e-cigarette-forum.com/fo...14-vape-responsibly-campaign.html#post5885778
The notcigs electronics protect against reverse batteries, short circuit, over current, over temp, and have a low voltage cutout. Using an unprotected battery in an APV where at the APV level you get every protection found in a battery protection circuit is a reasonable thing to do, to me. That the vendor also, very clearly, in caps and red text, on the page you have to go to to buy the batteries, says don't use them in unprotected devices, also sounds reasonable.
(If someone wants to use protected batteries, to double up on the electronic APV protections, or imr for a softer fail mode, that is super, as a personal choice.)

Safety
One important advantage over other lithium-ion chemistries is thermal and chemical stability, which improves battery safety.[6] LiFePO4 is an intrinsically safer cathode material than LiCoO2 and manganese spinel. The Fe-P-O bond is stronger than the Co-O bond, so that when abused, (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration.[citation needed]
As lithium migrates out of the cathode in a LiCoO2 cell, the CoO2 undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO4 are structurally similar which means that LiFePO4 cells are more structurally stable than LiCoO2 cells.[citation needed]
No lithium remains in the cathode of a fully charged LiFePO4 cellin a LiCoO2 cell, approximately 50% remains in the cathode. LiFePO4 is highly resilient during oxygen loss, which typically results in an exothermic reaction in other lithium cells.[4]
As a result, lithium iron phosphate cells are much harder to ignite in the event of mishandling especially during charge, however any battery (LiFePO4 included) after exhausting chemical ability to absorb any more energy can only dissipate overcharge energy as heat. Therefore, unlike commonly cited impression of bullet proof safety, with high enough rate of prolonged [over]charging, at some point it will ignite itself and its surroundings potentially causing catastrophic outcome. It is commonly accepted that LiFePO4 battery does not decompose at high temperatures.[6]

After further thought, I don't think it is sufficient to just include safety information with the device in shipment.
The problem is that the consumer has already purchased the device.
I believe that prior to purchase, like when you look at a device on the website, there should be a pop-up similar to this at a minimum.
This Name of Device is designed to be used with size, type, voltage, etc batteries and x.x x.x OHM atomizers/cartomizers.
Use of other batteries, battery configurations, atomizers/cartomizers in some electronic cigarette devices have been known to cause explosions, fire, property damage and personal injury.

That still wouldn't have mattered in this case because the man it happened to was not the person who ordered it. Its a good idea and I will support it but in this case it would have been no diffrent

It might have made a difference since we don't know how aware the purchaser was. The same warning should also be included with the device in shipment. In this suit, even if the device design stands up, the failure to warn will probably stand.
Could be the reverse though. The warning was definitely there on the site, part of the user manual to be downloaded from the site and in their subforum, specifying which batteries, even to the exclusion of other LiFePO4 cells, to use for "6V" and the required charger for the cells, similarly to the exclusion of other chargers that can charge at various settings for different battery chemistries. Meaning it was something like buy this set with these batteries and charger included, or buy the device independently for intended use with these specific batteries and chargers. But whether the device holds up to use with lithium primaries, possibly charged, or insertion of any number of different energy sources is another issue more so dependent on engineering of the product itself for any number of possibilities rather than warning against those possibilities or failure to recommend "proper" use. Maybe part of the case, maybe not.
I like it! It has to be stated at the source of purchase. This will go far to educate buyers. bnrk
