14500 or AA?

                                                                                                                                                                                                                                                                                                                              What is the difference between the  AA & 14500 rechargeable battery? I have an Ultrafire C3 SS, and a http://www.manafont.com/product_info.php/sipik-sk68-floodtothrow-zooming-cree-q4-convex-lens-led-flashlight-black-1aa-p-5821 on order. Will one battery out performe the other? Can 14500s be charged in a Duracell 15-min charger? Also, what other devices can they be used in ex. digital camera? Any advice on brands, price, or websites would be greatly appreciated.

Thanks Dave

Those 15 minute chargers are cell killers - they are throwing 8 amps through a poor cell.

But if you are lucky, it won't charge a lithium cell. If you are very unlucky it will, shortly followed by an explosion and fire. I suspect it'll reject a lithium cell but I'm not about to try it.

14500s charge up to 4.2V so are not going to be charged in a charger intended to charge to 1.4V. The C3SS gets very, very hot on high with a 14500. If you can hold it for 5 minutes on high you are either wearing gloves or have extremely heat-resistant hands. Or have a higher pain threshold than I do.

My one does about 130 lumens on an NiMH, and 250 on a 14500.

I don't seem to have numbers from the Sipik on a 14500.

Don't use 14500s in anything not designed for the higher voltage (3x as much as a freshly charged NiMH). You will kill the device.

 

The numbers from my light tests are always to be found here.

Don't even use 14500 when DX (or other sellers) says "Battery Configurations: 1 x AA/1 x 14500 Ii-on battery". Always check comment before or you can kill your flashlight (one example is akoray K-106..)
The C3SS works with AA and 14500 but with 14500 is almost impossible to handle without gloves!

While we are on this topic, from what I have read, AA Eneloops can be safely substituted for AA ALkalines or AA Lithiums, correct?

Rats, finally sold my 2010 509hp Mustang...now I can buy more lights!

Sold the red one too! Now guess what I drive, doing my penance for 500 hp commuters...

Yes. The Eneloops will quite often give more output due to lower internal resistance despite the lower nominal voltage.

Hmm.. 14500 in a 15  min charger. That would make an interesting video. Hopefully it would not charge but if it did I would expect an explosion.

Thanks for all the good info. I found 4-14500's 900ma w/universal charger on E-Bay for $11.99 W/free shipping. I am going to use the charger for my AA's and ditch the 15 min charger.

Thanks everyone for the help.

Hi Dave,

Just confirming your new li-ion charger is for charging your new 14500s  and not for recharging NiMH AAs right?

Remember the 14500s charge up to 4.2 volts. (Or are you saying you are getting a charger for both chemistries?)

First of all buying batteries or chargers on ebay is a bad idea

Absolutely the worst place to buy important things like chargers or batteries ..Too many fakes , too much junk ,

 

that'ts a really good question ..Are you thinking about charging nimh with a lithium ion charger ??

 

And those 3 words are pure death anyway .. 15 minute charger ?? huh ?? on what planet is this ?? if a nimh charger doesn't take like 4 hours you can almost always trust it's junk.

 

You need to study this stuff before you buy

Sorry to get ya all worked up. http://cgi.ebay.com/4-x-900mAh-14500-rechargeable-battery-charger-AA-AAA-/130502134632?pt=LH_DefaultDomain_0&hash=item1e62888b68 Is what I ordered.

I have a similar charger I use for my 18650's with no problems (also e-bay). Guess I got lucky with my 15 min charger I have not had to buy any batteries for my camera for the last 3 years.

Anyway, I know some of these questions seem dumb to some of you. I would rather ask it here rather than ask  someone in china named Joe.

The charger will also charge my 18650's so that's bonus.

I guess another greenhorn question would be   Universill means so onley for Li-ion batterys?

If the batteries are fakes I wonder if they will work in my fake Sipik flashlight?

For lithium-ion batteries you need a specific charger that can only charge that type of batterie because the voltage is much higher than that of Nimh-batteries.

Do not use the wrong charger, it can be dangerous.

I use a Ultrafire WF-139 for 14500 and 18650's, and a Maha Powerex MH-C9000 for AA and AAA.

Every type of battery needs the correct charger, for the 12V battery of your car, you also have to use the right charger...

Dave, don't worry about asking "dumb" questions. Like Don says, the dumb question is the one that never gets asked. It's worthwhile to be as informed as possible when dealing with Li-ion batteries especially.

The charger on the eBay link provided seems to indicate that in fact charge both NiMH and Li-ion. It has 2 different outputs. I wonder how it knows which battery type it's charging. If it ever makes a mistake...

Hi Dave,

Interested to hear how the batteries and charger perform.

I'm no expert on Li ions but $12 for 4 x 14500s and a charger seems way cheap.

Assuming the protection circuitry/design doesnt kick in, I see the charger discharging the battery, but its all depending on its floating voltage.

Slightly off topic but I just stopped the wife putting 2 14500's in a tv remote. The batteries were dead so she thought she would change them and saw what she thought were aa batteries lying around. I wonder what would have happened?

Or maybe you would be able to set your TV Remote to "stun".

The charger and batterys should show up any day or week now (china) I will let you guys know how they work out.

If on the news you see any clips of a house fire due to battery explosion in Michigan. That might cause a delay in me getting back to everyone on how they perform.

Thanks for all the input. Dave

Been reading up a bit on Li-Ion batteries, having some basic questions as well:

 

1. Are protected Li-Ion preferred over non-protected?  

I read in some places some flashlights won't take protected--wonder which would be safest purchase for compatibility with flashlights on the market then (protected vs. non-protected)?  

 

2. It seems the light output on the same flashlight is normally doubled for Li-Ion vs. AA NiMH cells (assuming the flashlight takes both).  I suppose that would mean the runtime would be almost half on the Li-Ion's compared to NiMH's then (if I take TrustFire 14500 0.6mAH x3.7v = 2.2WH, a bit less than an Eneloop AA ...) ?

 

2. Was reading a bit on the BLF Battery database, I wonder what'd be a good choice for 14500 Li-Ion?

 

3. And I am reading that the sizes for the same Li-Ion type can vary quite a bit among different brands.  

Wonder if the ones in the database are those that conform to the standard sizes--and if not, would be great if there'd be an additional column for the actual battery dimensions... .

 

Thx much for the info... .

if you're not sure, definitely get the protected, and yes the light will be a lot brighter. i've had good luck with the trustfire flame protected 14500 batteries, and they fit everything i needed them to fit.

I have 3 of the exact light… they will run on 14500’s but don’t! They get way to hot! SS is not a good conductor of heat. I love that little light, but I also question the durability of the switch with high amps, if the driver is changed!

EDC rotation:
KR4, SST-20 FA3 4000k (favorite!)
FW3A, Nichia 4000k sw40 r9080 (second favorite)
FW1A, LH351D 3500k (third favorite)
FW1A, XP-L Hi 3A
FW3A, LH351D 3500k

I have been using 14500 and 10440 (AA and AAA sized) batteries since the cree led came out. I have only used unprotected. Mainly because of size difference (protected batteries sometimes will not fit/ bigger). Also because I only use these batteries in single celled lights. The reason for protected is that the batteries can explode. This happens when drained too much. It is a bigger danger in lights using more than 1 battery. I would strongly advise against buying any batteries or chargers off of ebay. I once bought fake Duracell NiMhs. I would recommend that you purchase a quality battery from a reputable source. This is also true for chargers. I have been using Efest batteries lately. I don’t like the trustfire brand. You want to charge 14500 and 10440s at .25 amp. I recommend Mountain Electronics (online store). Prices are good and you won’t be purchasing counterfeit items or crap. I don’t use these batteries in anything but flashlights. I like them for small keychain (EDC) flashlights.

I just purchased the Tank007 E09 (10440). The Tank 007 E19 (14500). Both were inexpensive and perform well on 10440/14500. Both are small and light.

You need a charger for Lithium-Ion batteries

Unprotected li-ions are usually perfectly safe inside single cell flashlights because their drivers usually need higher Vin than the minimum led Vf, which is ≈2'5V for white ones.

By the way: LiitoKala Lii-100 + TrustFire high drain 700mAh IMR14500s -> Wonderful and economical combo. cool
