Are these protected or unprotected lithium cells?

I believe that they are protected. This is a rechargeable, but I haven't needed to use this one yet. It's a back-up battery.

The battery is a hard-shell protected Lithium battery ssimilar (but not the same size) as those offered by Sanyo (Eneloop). and other rechargeable battery suppliers. Regards,

I do not recall any 'protected' claim for this rechargeable, so suspect it is NOT... also, I found this website with additional information: http://www.lighthound.com/Rechargeable-Lithium-Battery-Information--Protected-vs-Unprotected-Li-Ion-Batteries--Lithium-Ion-Battery_ep_36-1.html

I guess I don't know what protected/unprotected lithium cells are. I can tell you that the one that came with my radio didn't last very long and the new one I ordered doesn't appear that it is going to be much better. It is suppose to be 3.7 volts but neither of them lasted very long. I can only get to to charge up to 3.58 volts by hand. I know that the crank is running the voltage up to the 5 to 6 volt range, so it should charge higher. Not sure what I will do now? Don't know where I can buy another battery this size at 3.7 volts?

I had issues with that. And the battery. Bad cell. Return was quick and painless tho. Amazon got me a new battery in 2 days. The charger I would recommend only using one that specifies lithium. Battery tender was out of stock so I got a battery tender plus charger. You can leave it on the battery for long periods and it's safe with lithium. I hope this helped.

My battery pack is a Lithium Ion type and model # DC9181 Type 1 20 Wh and is still going strong...I have 2 batteries that came with the set, a drill and a light and the battery got drenched and will not work now...I guess it is not waterproof...should be though.

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

What is not in the description is that these batteries are protected. In my vape I can't use them since I run sub ohm coils. And the batteries don't fit in my itaste vrt. To tall with the button top. The charger works perfect and the batteries last a long time when I use an atomizer that has a 1.2ohm or higher coil.

Honestly, I couldn't tell you. Lithium batteries can catch fire when modified, at least that's what the manufacturer warnings say for any Li-Ion/Li-Po batteries I own, so be careful! I've had two spare batteries for my MJX, and one of them has stopped working, so I'm not sure about the reliability/build quality for this battery. Perhaps this is a common issue with this particular battery.

NO!it should reject them.lithium cells require dedicated chargers.they could explode/vent with flame if improperly charged.

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.

Oh, thanks for clearing that up for me. But I'm kinda worried that they aren't replaceable. I've seen a few batteries die completely in a state where they aren't even rechargeable anymore. I hope these lithium batteries last if you can't replace them.

Hi James: I also thought they were lithium but they are not. They are an upgraded NiCad. The ones I bought are working great. Found out that you do NOT keep them on a charger all the time. Use until run down then recharge and remove from charger when charged. These have lasted over 2 years. The older non upgraded lasted 6 to 9 months but I kept them on the charger all the time.

i really can not recall but as i said in the review i would not buy these. all the ultimate lithium i received were bad and i received a refund on them because they would not charge. the rechargeable lithium are the ones i use and are great.

You need protected cells in all high-current flashlights such as this one. With batteries in series, it is impossible to protect each cell from one circuit - it has to be in each cell.

Good question. Mine were black and protected for sure (slightly longer) than any of my non protected green label batteries.

If you are referring to a case and in plastic then yes they are protected. I received mine on time and haven't had any problems so far.

These UltraFire 18350s are definitely not protected. Your device is not in any jeopardy from unprotected cells, the protection is against discharging the battery too deeply and killing it.

No, they are simply rechargeable batteries (excellent batteries for the cost) and like any battery of this type they rely on the devise they power for protection. Hope this helps, Have a great day.
