what is protected battery?

It protects Lithium batteries from being over discharged. It also protects the battery from being over-charged.

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

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

Not sure what that is, but the battery is kept in place by a couple of cotter pins. Hope that helps.

Yes. It has a gasket to protect it from the elements. I have mine mounted outside on my travel trailer to quickly turn off my battery and there has been no issues.

You can have connections to the "unprotected" side of the battery. Just keep them to a minimum as a large load can discharge the battery and the Battery Protector can not disconnect them to save the battery.

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.

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?

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.

I use it as the backup battery for my home alarm system. The control panel and battery are in the small linen closet in the bathroom, which is just off the bedroom. The battery replaced a previous identical battery; between the two, they have been in that location for 8 years, with no safety issues.

Usually, over 80%， device has overcharge protection to protect battery. The overcharge protection is coming with device not charger I think. Hope this helps

Mine was used for a home security system backup battery so I'm afraid I can't help you.

The Batt. is totally sealed. I see no reason why it would not work for your your Appl. & not ruin the Batt.

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

This product uses an 18650 battery. I recommend the "B" variant that has larger capacity also using protection -commonly referred to as a 18650B Protected battery.

There is an external battery pack that can be plugged into the lock when the internal battery is low or dead.

The battery requires a "cage mount" that has two electrical contacts on the bottom that match up to two contacts on the bottom of the battery.It also requires an locking pin that locks the battery in the cage and holds it firm against the bottom contact points. The locking pin on mine uses a key to operate it. Hope this helps.

It's not a mistake and it isn't a battery. It is a magnet taped to the inside of the box. It is used in conjunction with the metal located in the box lid to seal the cover/window/display case lid so you can see the device while packaged but it will remain securely closed during purchase, shipping etc..
