Good battery if a bit large!

Pros: Good battery for the price, the protection circuitry was a must for me.

Seem to be as rated which was a pleasant suprise!

Cons: These are a fair bit bigger than AA batteries, I bought these for a battery box modification and had to cut most of the Negative spring away & cut away a lot of plastic from the Positive end of the box

Bottomline: Best measure up to make sure these will fit whatever you want them for,  if they do, then buy them as they`re a great battery with circuitry protection.

great, beyond expectation

Pros: worked beyond expectation with the Q5-wc flashlight sku 28546, I left it on for 2-3 hours at max before it was empty, fits light with no issue with pcb, the circuit also works, and cuts out charging when full., using with charger sku 04151, had a bout 10 cycles on both batteries, and there has been no issues with anything.

Cons: none, minor imperfections on crimping, but it doesn't matter at all.

Other Thoughts: good stuff, seems like the rating is actual correct for theese things.

Bottomline: will definetly buy more, we are buying them + lights for all techs at work.

Great batteries!

Pros: Good quality, holds the charge well and works perfectly. I use it with my UltraFire C3 Cree Flashlight (sku 01993).

The circuit cuts off the discharge when the battery is flat, so you know when you have to recharge it.

Good price!

Cons: A little bit bigger than regular AA batteries (because of the circuit), but it fit well my flashlight.

Other Thoughts: I recharge it with my Universal Smart Quick Charger (sku 14885). It recharges really fast!

Bottomline: These are the first rechargeable batteries I bought on DealExtreme and I'm very pleased!

Pros: Finally, my first protected cells arrived.  Measured 3.84V which is good.  After charging with the 'OEM charger" (100% fully charged and went to discharge test...
The capacity is 857 mAH which is good since I expect less as experienced from previous 'fires'.
The battery cut off @ 2.65V and remained so until the load was disconnected as expected.
Perfact.  I do not have to worry about discharged to zero voltge wich generally kills Li-on cell.
Note: Sku 13820 type of charger stays at 4.24 Volt and truely 'tops up" the battery.  The DSD type cuts off @ 4.28, usually means internally the Li-on cells ia about 4.0 V meaning only 85% charged due to internal resistance.  You can tell by measuring the terminal voltage immediately after charging.
 
Cons: The one bid disadvantage is the length is now 51.8 mm instead of 50 mm.
This is big deal because it is too long for "AA" size.  In my case, I have to modified my battery cap.... not I wanted.
 
Other Thoughts:  
Bottomline: Since this "AA" size lithium cell generally is to replace 2 "AA" size in flash light, is a matter of adjusting spacer.  In the even the cells are arranged side by side as in radio or camera, this oversized "AA" wouldn't fit at all..
