10440's

Think I should share this information from my pm with kreisler.
(I have reformatted the pm and removed some other unrelated content.)

I saw the bottom of kreisler’s post.
“UltraFire Gray Protected red marked cell 254mAh-0.1A (repeated tests: 261mAh, 260mAh), or: typical if not charged fully to 4.200V: 245mAh) UltraFire Gray Protected *unmarked cell* 225mAh–0.1A, rest offline voltage 3.3V (repeated test: 229mAh)”

What is does it mean by red marked cell and unmarked cell?

remember i bought a PAIR of cells?

it is to distinguish one cell from the other.

i use a marker to mark one cell.

Thanks for sharing the PMs. Now everybody can see that kreisl is a nice guy helping fellow boardies in need ftw. i am the best!!

hehe..

How we do say here, no tienes abuela, eh? :stuck_out_tongue:

What does that mean? From my meager understanding of Spanish "you don't have a grandmother eh?"

Hi scaru
Yes, that is. If you don’t have a grandmother you need someone else (kreisler itself!) to do compliments / praise / be kind on yourself.

Thanks. :)

Couldnt figure that one out so I went to google translate. Does that mean "praise own shit safe"?

more like: Own praise, sure shit

There are 2 more options for protected 10440 which might get popular.
Hope there will be reviews for the batteries soon somewhere.
They could be identical or clones of those mentioned in the OP.
The protruding nub of the ultrafire one looks different as it looks smooth in the third picture on the site.

I have bought the Trustfire blacks.

Hi there BLFiers!

How2, have you got an iTP A3 by any chance to check them?

Very nice ! reminds me to check my 10440's , must be about a year or so since charging the one in my Maratac ..

Wow - 4.04 volts , and its been sitting in a drawer for about a year

No I want to buy the Ultrafire UF-T1

I cant vouch for the current crop of chargers , but the GTL charger is some what low current

for smaller batteries .

Ooops , thats the wrong way to do it ! - Been 2 years since testing charger ! damn .... Ok the right way now ..........

Ok , this is the right way to do it !

Where was I , thats right , the GTL charges at about 300mAh , now I cant vouch for the current crop of chargers

as this one is over 2 years old . But if you want a low current charger , more suited to 16340 - 14500 and 10440

then you may wish to cinsider a GTL charger [ cant beleive I said that ] , the quality is ??

I have never tried 10440’s as of yet. While I was buying a couple of AAA Balder TD-0 I decided, what the hell, and grabbed a couple of cheap ultrafire 10440.(not a brand I would normally buy). As its taken so long for the lights to be shipped, I’ve since ordered a couple of AW ICR’s and an IMR, so I guess I’ll be exploring the world of 10440. I already own a UltraFire WF-138B (10440/14500) charger with a max charge rate of 250 mAh, so I guess I’m good to go.

Now... what kind of li-ion put out 60mA at dead short? A dead one. Lucky. Imagine if you had mistakenly tested dead-short on a fully charged one .

Lucky it was in the charger ! + its a protected cell , so the protection circuit probably cut in .. + low state of charge , + it was an AMP meter , so probably may have killed the meter rather than the battery going boom .

Old4570 I did the same thing with a 16340 battery on my ultrafire wf-139 and Trustfire TR003P4 the results are

WF-139 varying 0.39 to 0.41 amps

Trustfire TR003P4 0.10 to 0.13 amps

The way I did it was Connected the negative cable the the positive battery and the positive cable the the charger Like you did in post #28 last pic.

My mistake one 16340 battery was reading 4.00v therefore got the above readin for the amps if it was empty then the charger would have charged at .460amps.
