Are these protected or unprotected batteries?

Mine were knock-off UltraFires. Branded as "Ultra-Firos". Notice how they branding is facing the opposite way in every picture. Contacted the seller. Stated it was a miss-print. Internals have no circuit protection. Stay away.

Mine were knock-off, they were called "Ultra-Firo's" Branding not visible in any picture. Don't waste your time with these. The correct ones are silver UltraFire from BatteryJunction.

I'm not sure. It is a sealed battery, like the ones you would find in back-up emergency lighting.

Yes. If you look up Duracell Copper top C Alkaline Batteries 1.5 volt specifies that they have insulating protectors. Hope that helps.Laurie

After watching the video you sent, the answer is, yes they are protected. I had never heard of such a thing. Thanks for making me a little wiser.

I don't think so, but the batteries have lasted for about 5 months so far. Also, batteries are far safer...

Just what do you mean when asking if "the batteries are protected">? I have bought over 12 of these flashlights as gifts and for my home, car, etc and never had a problem with the flashlights or batteries. If you are that concerned why not take it to a battery shop, have them look at it, and respond to your question?

Oops, I just realized that the Panasonic batteries sold on Amazon are not protected. So, to buy batteries from Amazon, I would go with Orbtronic Batteries see the link below. Given that the Panasonic batteries that are not protected I am going to order some Orbtronic batteries myself.ORBTRONIC 3400mAh Two 18650 PROTECTED PANASONIC 3.7V Rechargeable High Performance Li-ion Batteries - 10 Amp Dual Protection - For High Power 18650 Flashlights - Protective Battery Case IncludedJohn Campbell

These Hybrid batteries have a safer chemistry and a protection circuit, and are considered safe in most applications. However, unless your flashlight has protection circuitry built in, it is always advised to use protected batteries or, IMR chemistry batteries, when using multiple batteries in series.

No. They are 18650 batteries. Probably removed from a used up laptop battery.Ultrafire batteries are crap. You might get lucky, and get a good one, probably not.

Do not believe so,. [There are no markings on the battery to indicate they are rechargeable]

Both batteries and chargers are sold on Amazon. Search for "18650B Protected" for the batteries, and "18650B Charger" for the charger.

Well........I'm not sure what "unprotected" batteries are in YOUR case, but I have 4 different 18650 batteries and they ALL charge up and the charger LED DOES turn green after the batteries have a full charge. Now this is for ME and the batteries that I have. One of the batteries I have is an Ultrafire BRC 18650 3.7V li-ion 3800mAh , and another one is an Ultrafire BRC 18650 3.7V li-ion 4000mAh. The other two are in flashlights that I have at another house so I can't answer what the brand is for those. But as I said.......the charger unit DOES turn green with these batteries in there.

I am presently out of town and unable to look at the ones I have. I have never had a problem. They are always well charged and quite btrght when darkness falls. I will be home the end of the first week in Feb and would be happy to check and see if the batteries are replaceable. Off hand I think they may not be, I recall they are well sealed.

These are sealed batteries. That is a standard warning on all lead acid batteries. The chance of gas being released is very small. They are used on thousands of Jazzy motorized wheelchair scooters.

Im in MA. I store my batteries in an unheated garage for several years since ive bought it....no issues thus far. But i agree that they are so small....so if you are worried, just bring them into the house when it gets really cold.

Protected from what? These are high intensity batteries and the flashlight gets hot from the batteries. If I had the flashlight on for any length of time it would become uncomfortable to hold. So I assume if you need this weird size battery, because of it's high intensity, will heat up whatever you put them in.
