12/12/13... After 14 months, im still getting 240-260 minutes of use out of each recharge (avg use time of 60 min per day for 4+ days) under the following conditions: 1.) Note that this is when the transmitting unit is plugged into the ear-phone jack on a "powered" speaker. i dont bother with the volume controls on the audiomate... instead, i adjust the speaker's volume and that takes some load off of the audiomate's battery. But when the unit is plugged directly into an audio source (where no power is supplied for volume control), the transmitting unit has to work harder and therefore loses some run-time. 2.) I am usually within 20-ft of the transmitting unit meaning, im not walking outside or going into different rooms, so the transmitter doesnt have to use extra power to penetrate walls, doors, etc. Note that the further you move away from the transmitter, the more battery power it will have to use and consequently, you wont get the 240-260 min of run-time. 2.) I always run it to the point of complete discharge before recharging (some studies say thats not the best way to treat Li-ion batteries but it seems to work for me). Bottom line... after 14 mos use, it's holding up better than i initially expected. It might be good for another year or two?...

I am looking at doing the same thing for my wives hearing aids. Amazon has several Bluetooth transmitters available. I 'm still working on what transmitter to buy. One of the major differences is battery or wall plug. Some that run on rechargeable batteries do not transmit while recharging. I plan to install it in our theater room. Currently she uses "TV Ears 3.0 System" earphones (wireless & works great) for listening to the TV. They actually digitally process the sound so that the speaking portion is clearer for those that have a hearing loss. With Bluetooth, you will have to rely on the settings of your particular hearing aids. I am looking at doing the same thing for my wives hearing aids.

Mine worked fine. I read on one forum that high capacity rechargable batteries could damage the transmitter, but the manual didn't say anything about it.

According to the manual, the AC adapter only supplies power to the radio. It can switch from AC to batteries, but says nothing about recharging, or rechargeable batteries.

It does not come with an AC charger. The headphones operate on battery only. Battery life depends on usage. Although there is no AC adapter included, you can purchase one. I suggest you do, because if you fall asleep, your transmitter will drain the battery if left on.

Yes, the batteries can be used instead of the AC Adaptor, I do not know how long they will last though.

The radio can run on AC adapter (not included). Not sure if this will recharge the batteries.

It uses 4 AA Alkaline batteries, they last about 6 months more or less depending on how often it is activated. Alternatively you can use Lithium AA batteries but it's not necessary. This unit is just the outside transmitter, it requires an additional inside receiver (sold separately) which uses an AC wall transformer and needs a 9v battery for back up power.

It uses 4 AA batteries. You can use rechargeable batteries if you choose. Since it runs on batteries it doesn't come with an AC adapter. It is very energy efficient and the batteries last a long time. I've only had to replace the batteries 2 times since I bought it and have taken several hours of video and hundreds of pics. The first time the batteries were replaced with a cheap $1 pack and they lasted for 2 weeks. The ones that are in it now are much better and have lasted ever since. (about a month)

For the transmitter, there is a socket so you can plug in a 3 volt AC adaptor. For the headphones, no - I use AAA rechargeable batteries for it.

Hi, thay take a 9 volt battery. Thats one of the things that make them great, some of the other receivers takes a special batteries that can cost as high as $12 bucks a piece.. I hope this helps you..

PetSafe sells the special batteries for the receiver. They last us about 2 months. Amazon can put you on a subscription for delivery of a new battery every 2 months.The transmitter ONLY plugs into a 110V AC wall outlet.

I own a set for me and one for me wife, both work with the same transmitter. I don't know how significant it is, but one of the units shorts out on me when I add new batteries. It very well may be because they warned me in their literature to charge the unit for no more than 12 hours, and I forgot and left it plugged in for the whole weekend! Still using the other one, but for more info see a previous "answer/review."

The "receiver" uses a CR 2032 lithium cell, 3 volts, sometimes called a button battery, since they look like a button. The "transmitter" uses a style 27A, 12 volts, alkaline battery. Both of these are found at Amazon and most retail stores. Note that if the mounting tape is used, the screw holding the cap on the "receiver" becomes covered; most of these tapes are not reusable once removed -- something to keep in mind.

Hi David,The battery is reachargeable on the receiver and the transmitter and you should expect to get hundreds or recharges on both batteries. The transmitter and receiver batteries are replaceable and the manufacturer recommends that you do not open the transmitter or receiver until you receive the replacement battery pack. If you have other questions please let us know.Thanks, EZDogFences

The transmitter uses an industry standard battery : 27A 12 Volt 23-944 - They can be found at Amazon and many other places :http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords;=B0002LXXC4
