is the IMR 18350 800mah 3.7v High Drain Li-mn Rechargeable Battery with Flat Top, protected or unprotected?

Just do a general google search for "what is a IRM battery" and you will find your answer. Quick answer is yes, long answer is complicated.

they are unprotected a hot spring or similar safety device is recommended, they are a safer chemistry though and can be safely used within their amp rating

A flat round 3v lithium battery # CR 2032, which is under the top cover it just pops off.

There doesn't appear to be any protection built into these batteries. I took a voltage measurement while I had these sitting out of circuit and they had just over 4 volts several days after I gave them a little time in the charger.

All rechargeable (NiCad or NmH) flashlight batteries will eventually go flat if not used, just like the battery in your car unless it's a lithium ion or lithium polymer. To prevent it if you aren't going to be using it for a while, take the battery out, or keep it charging when you can to prevent it from deep discharging, which ruins the batteries fast.

18650 Batteries come in two versions, one "unprotected" and the other "protected". The "protected" batteries are just a tiny bit longer than the other. That might make the difference for you.

This light should always be used with protected 18650's, I use the protected Panasonic 3400 Mah cells from international outdoor and couldn't be happier.

batteries came in regular cellular warp. (don't understand what is meant by "protected batteries".)

I have one it is a backup battery that is hidden. So if the main battery would get cut or disabled the car is still protected. Its just an extra layer of security.

Protected means that the charger is "smart" and will not overcharge your battery. It also will not "short" if you accidentally insert the battery backwards. The charger charges specifically to optimize battery performance

There is no protective cover that I am aware of. All you will have is the extended cover (sticks out about 1/2" due do the size of the extended battery). The new battery life is well worth the inconvenience of the bulge. Be careful though, the cover tends to fall off/pop-out as it is only held in by a few flimsy plastic "clips". These tend to expand due to movement and heat and may pop off intermittently.

It is usually flat like other batteries but you may see some sort of bulging at the top of the battery (near samsung logo). Bulging in the middle is not normal.

***UPDATE*** According to Joel Koury, the battery is glued to the casing, hence not replaceable. Thanks for the update.--------------------------I would say YES. It's not like Monster would make a proprietary battery. It probably uses a standard 18650 lithium battery or something that is very similar and available to purchase from battery vendors. From the looks of it, there are two circular rubber disks (not the four rubber feet) that cover the screw holes on the bottom of the unit. Remove those rubber disks and unscrew the base. That should give you access to the insides including the battery. ***UPDATE*** According to Joel Koury, the battery is glued to the casing, hence not replaceable.

It has the standard protection for reverse voltage being applied to the Cree LEDs and to keep them from using too much current. Protection when using Lithium batteries is needed inside the battery itself. If too much current is being used or charged a Lithium battery can overheat and explode or burst into flames. Always used Lithium rechargeable batteries having the internal protection built into it.

Yes, the protected charger will also charge unprotected 18650 unprotected cells but keep in mind that they are unprotected. If they have a bad or damaged cell it will not help.

It's a lithium ion battery with built in circuitry to protect against overcharging/overheating
