Many people dont understand the risk from buying cheap Li-ion batteries, Li-ion battery can be very dangerous in general. Most report I've seen are from cheap/fake batteries. Do a quick google search and you'll find some battery exploding like mini bombs.

This flashlight is around the $12 mark at any given time, so this 'sale' isn't a sale. The marked-up price is never the going price since it's a 24/7 'sale'. It's a great item to post for reps.
The UltraFire batteries are basically your only option on Amazon.com for cheap 18650 batteries. As many reviewers (and third-party review sites) state, the UltraFire batteries on Amazon are re-packaged cells from old laptop batteries. An easy test would be to roll the battery along the table. A regularly packaged battery will not be lop-sided and roll normally. A repackage battery, such as the UltraFire brand, will be packed in with filler, and the actual cell inside will actually be off-center, making the battery roll along off-kilter.
However, I seemed to have lucked out. I purchased a $12 1000-lumen Cree-LED flashlight from Meritline and a $14 charger/battery combo from Amazon. The flashlight is about 600-lumen effective brightness (which is plenty strong for a small handheld), and the battery has held its charge for over two months and still going strong with 2-minute usage every other day.

Besides, that it is for flashlights around the house and again, just not that critical. And all the lights and batteries have worked fine although I really did only start to buy them a couple of months ago..time will tell.
But yes of course if money is no object, then buy the most expensive and reliable batteries and flashlights.

And none have exploded and burned down my house yet...am not saying it couldn't happen but the batteries work and charge fine and make the flashlight really bright.
Just look on ebay and find the least expensive ones and buy them and they should work. Sure you can pay 5x that amount for a more dependable and safer battery, but that cost/benefit equation is up to you to figure out.

Lots of good information. Ever since I've had a CR123A cell explode on me this past summer, I've been wary of cheap lithium batteries.

For $1 more, this one has adjustable zoom:

As for the red trustfires, I've got those but like the unregulated ones better, once power starts to go on them, it goes from super bright to nothing and you're in the dark. At least with unregulated ones, it starts to dim and you know you've only got a few minutes left until it gets really dim and you risk discharging the battery too much.

There are a ton of options here, many are crappy knock-offs with fantasy power ratings... Name-brand prices are sky high.
I strongly prefer the red foil-wrapped Trustfire batteries, and DX has them at great prices. DX tests capacity, and if it is overstated by the MFR, it will be "in quotes" with the tested capacity listed in the description.
The Trustfire's are considered "protected" cells, since they include a circuit board that protects them from under voltage and short circuit issues that can create fires. Ultrafire's suck, stay away! My favorite, made by Trustfire:
Trustfire 18650 (dia. 18mm, len. 650mm) -. 2/$10
There are a zillion lithium charger options out there, starting at $4... If you buy a cheapo, I suggest only using protected cells to reduce fire hazards...
Considering fire safety and overall convenience, I finally settled on the SYSMAX Intellicharge i4 JETBeam Nitecore Li-ion / NiMH Battery Charger V.2 $27:
The Sysmax is a great charger, charges everything (Lithium, NiMH, and NICD), in any combination, automatically, using the preferred method for each cell type. Super safe and super handy, even has a car adapter... No other charger currently supports all three chemistry systems, since some require constant current and the other constant voltage.
NOTE: DX items are made in and shipped for free from China. This takes about two weeks, so prepare to be patient.
