I'm sure wiser folks than me will chime in soon, but the general consensus is that anything with "fire" in the brand name is something to avoid - at Fasttech prices I'm finding $10-12 for two decent batteries, so the cost you're quoting sounds almost too good to be true (likewise with the 5000 mah runtime). There's a great thread that talks about battery safety in the RBA subforum, directed at sub-ohm builders but valuable for anyone (I haven't gone below 1.6 ohm yet but I got a ton out of it) - http://www.e-cigarette-forum.com/fo...-discussion-safety-battery-info-warnings.html

I just got a sigelei mechanical mod, and I was wondering what I need to know about batteries. I have a yellow ultrafire 18650 5000mah battery. I've seen similar batteries in a pack of 8 for $12 bucks or so. What should I really know about a good battery and proper care?
That battery is an ICR Li-ion battery, I can't tell if it is protected or not as multiple product listings do not say. Regardless, protected ICR batteries have fallen out of favor for use in mods in recent years with the advent of safe-chemistry, high-drain batteries such as IMR (Li-Mn) and even newer hybrid batteries.

My advice is to stay away from any battery with the name "fire" in the name. These are typically inferior quality batteries and not to be trusted for use in a mod. Fake Ultrafire 18650 battery warning - Page 4

For a list of recommended safe-chemistry, high-drain batteries:

the battery is protected, i think. It is not a flat top

It doesn't matter if it's protected. It has ICR chemistry and that is dangerous. If the protection fails and it sees a short it will very quickly vent and burn with flames. Put that in an enclosed space like a mod and you have the possibility that it will explode. IMR and hybrid Li-ion batteries don't burn so while they will still vent, there is almost no chance of a explosion.

For a lot more information on all this please read the links Baditude gave you in his post :thumb:

OMG....this battery talk is making me scared. I have no idea what kind of battery I have. My mom brought it up to me..said she saw a special on tv about e-cigs blowing up and being dangerous in their own ways.

Everyone should have a healthy respect for the power that is in batteries...any battery... Lithium ion (Li-ion) batteries are used in multiple devices such as flashlights, cell phones, laptop computers, as well as e-cigarettes. All have the "potential" to vent gas, some have the potential to vent flames, and if enclosed in a metal tube or box without vent holes have the possibility to explode.

IMR batteries are quite safe. Their chemistry is inherently safer than ICR batteries and do not require the IC that so-called protected batteries have. Use common sense and safe battery habits and the likelihood of a battery incident will be nil.

Stop using common sense and stop using safe battery habits and the chances greatly improve that a battery incident can happen.

Use only the right battery for the application you use. Use name brand batteries such as AW, Efest, EH, Orbtronics, Panasonic, Samsung, Sanyo, and Sony. Avoid using Surefire, Trustfire, and Ultrafire batteries. Do not use generic no-name batteries.

IMR (Li-Mn) batteries better suit our purposes than do ICR (Li-Ion) batteries. Never use non-rechargeable batteries or un-protected ICR batteries in a mod. If you can not identify the type of battery you have, then do not use it.

Never charge your batteries while away from home. Charge them on a flame-resistant surface such as a stove top, cookie pan, or pyrex dish. A battery should never feel warm to touch, if it does consider it to be unsafe and discard it. Use a quality charger such as Pila, Xtar, or Nitecore.

Do not carry spare batteries in an unprotected pocket or purse - use plastic battery cases. Batteries which come into contact with coins or keys can become extremely hot and vent gas, and some will vent flames.

When in doubt, use authentic red AW IMR (Li-Mn) batteries from a recognized authorized vendor such as RTD Vapor.

That's a typical eGo style battery. Best practices are, don't leave it plugged in overnight or when you're not there. Don't use a unknown charger. It's also safer for your computer if you use a wall USB plug instead of the computer USB port. Don't leave it in a hot car in the summer. Don't charge it in a car USB port, specially on a hot day. If the battery ever heats up during use, there is something wrong with it and you should stop vaping it immediately.

These things are valid for all batteries including cell phones, laptops, camera batteries, etc.

There are literally millions of these eGo batteries out there. They don't fail often and when they do it's mostly during charging and most of the time that's because people use the wrong charger with them. The hot car thing has happened a few times too.

I have a few of these batteries and I don't worry about them.

Hope this helps!
