a weird battery thing

[Zealous]

So, in my 14500 woodville I was fiddling around with my coil a bit moving it higher & lower to get it right where it should be with the air hole. Everything had been working fine while I was testing things out at first. But then out of no where it wasn't firing. So I put the battery tester on it to see what the voltage would show & it wasn't showing anything.

I took that battery out & put another fresh battery in. That one tested @ 4.23v. I put another different one in that one also test @ 4.23. Tried the last one I had & that one tested at 3.7 which was about right as that's when I normally take them out. Put the first one, the problem one, back on & it still showed nothing.

so I put it in the charger & charged it up & it seemed to fully charge. I put it in another mod (mostly cuz I was concerned about it messing up my Reo) to see if it would behave right & I think it's behaving sort of right. But it's draining faster than it should be.

Any thoughts on this? If I had over drained it it should have shown SOME reading when I checked it shouldn't it? And I wasn't doing anything unusual with it like a different coil or anything so I had been using it for no longer than what's normal for me before a charge.

Depends. Which battery is it? Is there a protection circuit on the battery? If so then the reason for a non reading is because the battery tripped the circuit when it drained too low. I wouldn't suggest using a protected battery in either case. Imr batteries are best.

It's an AW 14500 button top. And it's 1 of 4 I have in regular rotation for this mod. The other 3 behave like they should but this one is acting weird. I got them all at the same time but I do understand that their "life" begins when they leave the factory so I guess it's not unreasonable for this one to just be older than the others. Still it's weird though & I don't want to be messing with a faulty battery.

Black or orange? A zero voltage reading would point to a tripped protection circuit. The black ones are li-on and have a protection circuit. Most good chargers are capable of resetting a tripped circuit.

If orange, either it has been dropped and is damaged in such a way to only allow an intermittent internal connection between the cells, or you didn't get a good connection with your battery tester when you got a zero reading. The orange ones are IMR and do not have a protection circuit.

I hope that helps.

If its a black battery with a silver sticker then its protected. So either a short or over discharge set off the circuit.

It's red (or orange I guess you are saying). It hasn't been dropped. I have kept them in the same battery case together & I don't take them out of the house unless they're in the mod. The mod has never been dropped either.

why wouldn't it make a good connection to the tester? The one difference between that battery & the other 3 is that one had nolax (sp?) on the tip since I had put it on the contact before putting that battery in. Other than that it's not any different than the other 3 that I can tell.

Well, I have no way of knowing what sort of tester you have or how you used it. So, I really can't speculate too much as to how or why you might not have gotten a good connection.

What I can tell you is this: Getting a zero voltage reading from an IMR battery is unusual. Even if you drain an IMR battery in something like a flashlight - just turning it on and waiting for the bulb to completely dim out -, there will still be at least a few excited electrons floating around and they will become evident in a short amount of time... Even as short a time as removing the battery from the device it was drained in, setting it on a table, and touching both ends with the probes from your multimeter. I would expect a drained IMR that got to rest after discharge for 5 seconds to indicate at the very least a couple or three tenths of a volt.

All of that said, if you have any suspicions about any battery you use, discard it and replace it.

Well, I'm not sure how I feel about that battery right now. It's working in another mod & I'm keeping an eye one it. But I also thought is was really weird that it didn't have any reading with my battery checker. The battery checker is one of those type you screw onto your device & then fire it to see the volts reading. And the other end can have a topper screwed in so you can see what the voltage drop is. The fact that it wouldn't read just that battery but read the other 3 without a problem makes me wonder.

When in doubt toss it. Batteries are cheap compared to er visits.

That would explain why you would not see any voltage from the battery. There is a cutoff on that type of battery checker. (On my particular display, it is 2.8 volts. If the voltage of the battery is less than 2.8, it will not show anything.) That is why I use a real multi-meter for troubleshooting.

Thanks for explaining. I'm getting a new multi meter today but I've been using the volt checker I have since it's worked fine for checking where I'm at with battery levels thus far. As you said though, not so good for when there's a problem.
