No battery, it come with a charger. You just plug the charger into the outlet and hook / plug it into your Silver Sonic and wait for it to charge.

This is a very small device without serviceable batteries...no snap opens etc...it is recharged automatically via the usb cable. The batteries will last for at least one hour or longer...I let my dog run and have made videos much longer than an hour...and still have some battery left...I shut it off intentionally...never had a problem with not having battery power available...but I also make sure that it is fully charged before using...I leave it plugged into my computer before use...

no battery, not rechargeable. it plugs in the outlet, or it can be plugged in the car.. I use it only at home, not in the car.

4 double A rechargeable. They came with my used one. The charging cord is a usb like a cell phone. Im sure you can buy a different one. As long as you want to listen to it plugged up you can but it will NOT change while you listen to it. Have to do one or the other

Not sure what the requirements are but I run mine off of a 10 amp 12 volt deer feeder battery that runs my 32 qt ice chest radio powering 4, 6" 8 olm 120 watt speakers. A fully charged battery will last about 18 hrs ! Hope this helps!

it's rated for only 118 minutes per battery...that means one lousy 2 hour run. Meh, I will stick to my Petzl headlamp that uses AAA batteries or my Diamond Sprint headlamp that has a USB rechargeable battery.

Great Questions. I have had mine for almost a year. I use it several times a week and it is great. It charges in little sunlight. I experienced discharge of battery and replaced the battery after a year ( keeping in mind I used it on a daily basis but I let it sit for about 4 months). My suggestion is to remove the battery for long term storage or when you need to use it or only putting battery in once every month to recharge if needed. I have found it very useful when camping, in the office, and in power outages for getting emergency alerts when the power goes out. From my understanding you should be able to find a replacement battery (only one needed) on amazon for around $10 (Ambient Weather WR-BATT 3.7V / 800 mAh Rechargeable Battery (LIR123A)) . One of the reasons I chose this unit is because the rechargeable battery could be changed. Allot of these rechargeable type units the battery can not be changed. But overall the reception is good, all the charging options are included with the unit, the unit recharges small electronics, and it is compact and lightweight. The volume is not overly loud, some may want a louder unit but i think it is loud enough. I would recommend this unit if you are looking at alternatives like this one for a reasonable price.

It does not ship with a rechargeable power source. You can use rechargeable "AA" batteries in the radio and they will recharge if given an external charger (not provided) like a USB-based cell phone charger. You will need a standard mini-USB (not micro) cable.

It uses a button battery, I have owned it for almost a year and use it all the time without major issue. It uses the ultra lower power consumption bluetooth transceiver so I wouldn't worry about battery life. It is not rechargeable though, you have to buy a new one when it dies.

Can't remember if it included batteries, but you don't want to use those anyway. Have your own 9-volt. Other than this, all you need is some kind of soundboard/speaker system to plug it into -- uses the larger, 1/4" jack, comes with the cord.

I am not sure exactly. But I will tell you the batteries drain really fast. I would recommend the rechargeable one.

The batteries are not removable. You must charge it periodically. It has never gone dead on me, I just plug it in to charge from time to time. I believe the battery life is given in the specs- something like six hours between charges- plenty of juice for a teacher. You will not use it plugged in, I don't think, because this amp is very portable. You can walk around and would probably not want to be attached to the power cord. (emergency charge only!)

i am not sure what your specific question is....... i will answer this way. i have one of these and it is fantastic. it works very well but i do not use rechargable batteries in it. you have over 100 hours of life with regular batteries. rechargable will probably be less but then again you can recharge them. as far as the picture goes with mine i can make out the grain pattern of wood several hundred feet away. it is a great buy

Yes. I put rechargeable batteries in mine and can just plug it in to recharge or to take power from the outlet. It's a nice little amp. The sound isn't as rich as even my 25 watt Crate practice amp, it's very portable and packed with features.

It comes with Standard ++AA battery, one of the cheapest option. It can be rechargeable also.

For me the batteries lasted quite awhile. I used it for short term trainings and a trip to Africa. I only used it at night when I was sleeping. If used more than that it might not last long. I didn't try rechargeable.
