Pros: Quality seems good. Stays cool while charging. Shrink-Wrap on batery secure.

Cons: None, so far.

Other: I don't know how if this battery will out perform ultrafire ones. But it is worth to spend a little bit more for me.

Pros: Lights up the Ultrafire WF-500(SKU1317) with a single click everytime so far! And thats with the WF-500 lamp drawing around 3amps!

Cons: None so far...

Other: I have no regrets buying these.

I have no doubts that these cells are good quality and can withstand high current applications.

Pros: This battery lasts a VERY LONG time. Build quality is good. Does not heat up when used or charged.

Protected for shortcircuit and over/under drain.

Cons: None.

Other: I would keep buying this brand again as a good source of 18650s!

Pros: I don't believe it! way better than the Ultrafire. On my WF400 both Trustfire and Ultrafire batteries fully charged and rested the Ultrafire current rating at the battery 650mah while the Trusfire is at 900mah!!!

Cons: The protection circuit is not flush at the bottom has a noticeable angle.

Other: Buy these instead of the Ultrafire.

Pros: -Cheap price (relatively) -2400mah, high capacity! -Takes only 2 hours to charge (using sku 5837) -Has the PCB and short circuit protection that puts me at ease when I put them in my high end flashlights.

Cons: -Mine came defective (1 of them)

Other: Good bargain for the price, but watch the safety issues.

Pros: Cheap protected 18650 batteries - Great in applications that require 2xRCR123A's granted the application has ample room for the slight diameter increase and decrease in voltage is not an issue - Great runtime - Color scheme corelates to the protected status of the batteries - Short circuit protection - Protects your equipment from malfunction
- Long Run Time
- Quick Charging

Cons: None

Other: If your looking for a well rounded protected 18650 batteries then this is the one to get.. In fact, get these over the UltraFire ones since they seem to be better and cheaper..

Cons: -wrapping may be a little flimsy.

Other: if you want cheap well protected 18650 batteries get these. the ultrafires are slightly more expensive. these are good
