What type of Li-ion battery does the sensor use? I thought it doesn't until I read the detail descriptions.

It doesn't have a battery, at least not one that is user serviceable. The light socket provides power back to the sensor.

I have no idea. I have used it now for over a year: it plugs directly in to the light socket, works exactly as described, and is powered by the electricity it's plugged in to... so (a) I am not sure what sort of Li-ion battery it may use, (b) not sure that it matters, and (c) the product has worked very well for me in very cold weather, very hot weather, and in continuous usage for over a year.

I don't think there is any battery in there. You need to connect it to a socket.

There is no battery. The unit gets its power from the screw in bulb socket. This device works pretty well.

As I understand this type of batterires Lithium-Ion can be charge at any time without any damage because they don´t have memory efect, mine Works perfect and I charge it whenever I want

We have an older model, and have a recycle bin on the floor under the sensor. I have found if my wife puts something in the bin that blocks the sensor (a few inches away), then the batteries go dead in a few days. Otherwise, it usually more than a year between battery changes.

To tell u the truth. I believe its a lithium battery. Charges, then runs about 2-3 full mivies off of a full charge. Only thing I don't like about it was that it looks like a huge CARS car, lol. Catch my son playing with it like its a toy all the time. Lol. Otherwise. Awesome product.

The description on the back of my battery rates it as 7.4V 2200mAh. Li-On isn't mentioned -- assume it stands for lithium ion, which these are. Work great in my Core micr+wire gloves, now going on four years! Got new batteries a few months ago. Caveat: I can't get more than 2 hours out of batts without recharging, and usually a little less. I keep a second pair charged for longer periods. And, recharging fully usually takes about 4+ hours. Still the best thing I've found for my colder-than-normal hands during Colorado foothill and mountain days below about 30F. The gloves are even better fitting, more flexible, and sleeker than most outdoor activity gloves. The description on the back of my battery rates it as 7.4V 2200mAh.

Thanks for your question! According to the manufacturer this is a Lithium battery. I hope this helps!

The battery just plugs in so it can be replaced. It is Lithium Ion or Lithium Polymer. Google the part number online or check at a Batteries Plus store. The trick is getting the right size and it looks exactly like the ones that run my RC helicopter and plane.

3.75 lithium ion. Not something you can buy at Radio shack but you can find them online. You'll probably never need one if you take care of it.

It uses one of those quarter-sized lithium batteries. Sorry not sure what they're really called.

Hi Charles,The Sensor or Transmitter battery is a standard CR2032, 3V coin cell. Mine last as long as 6 months, since a Transmitter wakes and sends a short burst only as the door or window begins opening, closing or the battery is low. The Receiver runs off a 12VDC wall wart with a 110 to 120VAC input.

All the sensors have batteries included, they are lithium I think (cant remember) and are odd size ( much shorter than an aaa). My parents system is still going after several years so they are good ones!

I have two multi-sensors in service since Feb 20, 2014. Both currently report battery level at 75%. Note they have been at this level for a while. At this rate, I am expecting a 9-12 month life span.

It's a proprietary Canon 3.6V Lithium-ion battery. But, the camera comes with a recharger.I like it.

I normally waited until I got a low battery indication. However, I don't believe that modern lithium-ion batteries have a "memory" like many of the batteries of a decade or two ago.

Hi u can use either battery I use the 9096 nicad it's cheaper than lithium ion advantage to lithium ion is it will last longer before a charge but nicad is great

16650 lithium ion's work great in mine. Get a good quality charger and batteries and don't leave any lithium ion battery charging unattended. That includes cell phones, tablets, laptop computers, etc. Unattended includes over night.

Good question. I would guess it is a Li-ion battery which you simply recharge and get several years out of it. If someone was to replace the battery after several years; the battery would likely cost more than the device.
