does the transmitter uses 9v or AA batteries?

these transmitters take 2 AA batteries and last at least 4 hours of full use. I have used both Sennheiser and Sure PEM' and the GTD PEM' are no different in quality.

uses 2 double A batteries, but we do not recommend this item, even after repair can only use one side.

AA batteries in the transmitter and a built in rechargeable is soldered in the car

It can use rechargeable 9 volt battery just as any device using normal Duracell AA battery can also use rechargeable AA cells.

I'm sorry, but I don't remember. I think it was the AA batteries as I do not remember having to buy a 9v. I gave as a gift.

It actually takes both a 9V and the AAA batteries. One is for the device to actually lock/unlock and another powers the wireless features is my understanding, but it definitely takes both.

It uses one 9-volt battery. I have used both disposable and rechargeable, both without any issues.

Yes, it does work with a 9v battery. It will not reach full potential with a 9v battery.

I use AA Duracell Ultra. I have no idea if they will accept rechargeable. BTW, I will soon order another transmitter because they have worked so well

No, it uses two AAA batteries and this is one of the main reasons I bought it. I use rechargeable AA and AAA cells and avoid 9v if possible.

It uses the 9 volt batteries, you could use rechargeable 9 volt if you wanted to and they were available.

The collar has a low battery indicator. I have not had the kit long enough to see if the transmitter has one. I am still using the original 9V battery.

yes, the transmitter has an internal rechargeable battery, it does not need to be plugged in, in order to work

I don't remember the specific battery types, but it comes with a complete set for the transmitter and receiver.

Yes, I have three sentry wireless transmitters that all use a plug in power source. The earlier sentry's included one, the newer do not. Pick up a universal battery eliminator, available at such as CVS or RiteAide or Walmart. These can usually be set to different voltages, I find 12 volt works better than 9 volt and dosen't burn out the transmitter.

I do not have a 9V battery in mine and I unplugged it for five minutes just to test this. It did not seem to lose its tare weight or configuration information.
