This is the key:
Too much for a 10440.
FWIW this is a decent charger, a bit slow on the big boys but they usually come off the charger at a hair less than 4.2V... a good thing.

Then there's this: DealExtreme: $8.76 TrustFire TR-001 Multi-Purpose Lithium Battery Charger. While its specified as 4.2V 500mA, end user "Scalex" in reviewing it lower on the page measured the charging current on a pair of 10440s as only 27-30mA.
... and that means I have to be into batteries. Don't particularly want to, but until one of you guys mod up a nuclear-powered PV ( Oh yeah ,I'll drive my PV to work!), I'm stuck with 'em. If you want to learn more about batteries and chargers and why it's important, skip to the links below because the remainder of this post is mostly to help others.
Many of us hope or plan to be doing this for the rest of our lives. That's a lot of batteries bought, and many, many more charges and discharges of those batteries and thus all the factors we have control over ( our choices and behaviors), are only part of what raises and lowers our risk. If you think all you need to do from here on out is use the charger that came with your ecig and buy whatever battery is on sale as long as it's protected, you just raised a risk you could have avoided.
All batteries and chargers are definitely not created equal and since we're going to be sticking them in front of our face...we should give them their due. Which is that we should pay them some investment of our time. There are unprotected batteries I trust further than many so-called protected ones. Battery tech doesn't change fast like computer or ecig tech so we can easily keep track of the small bits that are essential to us. All li-ion batts need your attention both charging and discharging. Don't let it discharge too far down or get too hot. These two usually happen together and it's caused by letting the battery drop too low before recharging. It can no longer supply what is being demanded of it and gets hot about it. Don't go there. Also, taking Li-Ions all the way done to dead shortens their life or as does leaving them on the charger after they are fully charged. Everyone that knows more than I do ( The girlfriend reading over my shoulder just said, " That IS everyone!" Feels like I'm dating Don Rickles. Ow !) about batteries recommends charging well before they take a big hit in voltage and pulling them off the charger before they are fully stuffed. So, overcharging is not good and neither is fast charging I'm just full of good news. good. At best, it is bad for the battery, at worst it is potentially very bad for you. Reduce your risk by getting a good or at least decent charger. This is considered a decent charger so long as it's not the "old" model. (Different manufacturer)
Do yourself a favor and research protected vs unprotected and batteries and chargers just the way you researched e-cigs before you bought one. (Ok, in some cases your going to want to research better.) As I mentioned above,"There are unprotected batteries I trust more than many so-called protected ones." Unprotected batteries used in series ( That's two or more in the same device and not just ecigs. Flashlights, anything.) need the most attentiveness to their own set of "rules" and should always be used together. Once together, always together, till death do them part. When one of the set goes dead you change BOTH( or ALL, as the case may be) and create a new set out of (preferably) new, never used batteries and never pair the survivor up with another battery. If you have a device that you can use it in alone great, if not, pitch it so you don't use it with another battery. treat 'em like the bulbs in your headlights. If they went in as a set and one dies, the other, barring an accident, is probably on it's last legs. the difference here is that if you want to run a mismatched set of bulbs, ok, but NOT OK with unprotected batteries that were part of a set. A good single unprotected battery ( just only the one in the device) still needs attention to charging and discharging.. A poorly made "protected" battery is more risky if we believe it is safer.

Good post. Here are the links that you mentioned.

I bought protected 10440s from Dinodirect and they are NOT protected.
I purchased [FONT="]the Precise from Super-T and had a hell of a time. This unit needs the extra length of the protected batteries or it does not fit (unprotected are too short). I believed I HAD protected batteries, had to make a conductor from a pen spring to get it to work.
[COLOR=DarkSlateBlue]I just ordered the protected batteries from [/COLOR][/FONT][/COLOR][/COLOR] [COLOR=DarkSlateBlue][FONT="]DealExtreme - the picture look right and it says "[/FONT] [FONT="]Over charge and under/dis-charge protection." Hope these work, I like the Precise, would be great if I could get it to work without my homemade spring!

As far as I know AW doesn't make a protected 10440
. If they do please prove me wrong, 'cause I'd love have some.

If they are the grey TrustFire ones they will work fine in the precise, that's what I use in mine.
Nope, they are blue, and trust me - these don't fit. I took a spring from a pen and fit it to the inside of the switch, cut it until it just makes contact, and it works but worries me as this is not how it is supposed to work!
Hopefully the protected batteries won't take too long to get here.8-o8-o
My bad, I wasn't very clear. I was refering to the ones you ordered from dealextreme.

Maybe they were mislabeled online at the time I ordered them. Looking at the receipts now, it does say unprotected. Not sure why I said that now, sorry. Maybe it was wishful thinking.
AW does make a 10440, but it is not protected. From what I have read, it is also slightly longer than most unprotected 10440's.
