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.

The coin battery on the part that attaches to the garage door lasts a long time. Ours lasted over 5 years before needing replacement.

The door sensor uses CR2032 coin cell. The receiver is connected to AC (110V).

The battery is a Li-ion battery, 3.7v, 1700mAh/6.29Wh. Even though it is branded as a D-link NP-120, other battery mfgs make this same battery. Just type in NP-120 battery in Amazon search. The NP-120 is used in many other electronic devices and seems to be available from many sources.

The battery that it uses is the small round one like a watch would use or digital scales. I haven't had them long enough to know but would expect several years from them based on the battery type.

It lasted over 2 hours straight off one charge. I don't know what kind of battery is in it but it is rechargeable :)

I looked on the battery and there is no information. I don't seem to have the literature that came with it. Sorry.

It uses a CR2032 Lithium battery, availble for small $$ here at Amazon, & at almost any drugstore. Average life -- this tuner draws very little power. I have played for many days, hours at a time, never turning the tuner off. The battery is still doing just fine. In other words, battery life is quite lengthy.

I don't know - it was a watch type battery. I threw the whole thing in the garbage after a month.

It uses a CR2032 battery. I have not needed to replace my battery yet, but looking at the unit, I see an access plate on the backside of it. It can be opened using a coin. Replacement should be very simple.

As others said, it is a CR2032 battery, which is a round button-style battery. One thing to note: when it comes time to change the battery, all the settings and the info in the memory will be lost, so it will need to be reset.

It actually came with an extra battery. It uses the CR2032 and lasts about 2 months.
