If you follow the instructions and only keep the collar on for the recommended amount of time or up to the max recommended per day, the charge on the lowest setting I used would last 4 to 5 days and then need to be recharged to its fullness which doesn't take that long at all. One note: I opt to use it for the max amount each day for 2 days and then started dropping it down to really only an hour after 5 days and then just leaving them off but keeping the collars on them for a few hours and eventually the barking completely changed in about 3 weeks that I didn't need the collars at all anymore. They are very intimidating at first and I know some people don't agree with this type of behavior corrections, but if used correctly and really at the lowest setting, your dog will get the idea quickly and will immediately adapt to a well like behavior. I did think it was a bit inhumane at first but like I said, I followed the instructions on the SportDog website and the 3 weeks of use I can say turned off the excessive barking that all the other small priced products couldn't do. I even bought the Bark Dog House, the remote Dog Bark Controller Clicker and nothing worked but this did. I think what really made this easy is that I was able to get to the result within 2 weeks and I felt great when I was able to just put the collar on but in the off position and they controlled their barking as if the collars where on and activated. I thought without them, they would soon go back to barking, but its been 2 years since I used them and I love my dogs more now than at first because they were out of control and I had neighbors complaining. They Bark now, but Bark when a dog should Bark. Their not Bark-Less Dogs after using the collar, just a behavioral change made the world of difference. Good Luck

I charge my dogs collar once every 3 days. I put it on him every day for about 10 hours a day. It usually takes about 4 hours to recharge so I charge it overnight. The charger has a built in shut off to keep from overcharging the collar.
