Why are all the batteries Positive and no Negatives? They wont work.

Almost all, if not all button batteries are stamped with their brand name, type I.D. and a positive symbol on only one face of the button battery cell. Since the opposite, rear, or unmarked face of the battery is always the opposite polarity to the marked polarity, and considering the marked polarity is always positive (+), the opposite face will be negative and thus no negative (-) mark or stamp is required. With button batteries their proper installation into a product, e.g. a watch or calculator, is normally assured by their physical stepped edge design which dictates in what orientation they must be installed, i.e. which face should face into the device. Normally this would be the unmarked face. The marked face you will normally see after the battery is locked into place. If the battery's power is exhausted and it is properly installed, then the device it is to power won't work. Normally putting in a fresh battery in its correct orientation will get the device working again. If that doesn't fix the device, the device is either defunct or you may have installed yet another exhausted or dead battery. A voltmeter is really the only practical testing tool that can tell you if a button battery is exhausted, that is to say dead.

My cats meow worked fine when the batteries were installed so I don't know what the problem might be. Have you checked to be sure you have the batteries installed in the correct direction--the negative and positive terminals are indicated on the battery holder to show which direction to install the batteries.

It could be that the batteries you recieved were not connected correctly or they might be defective? Thats all i can think it can be. Or maybe your charger is going out? it could be multiple things really.

I had the same problem with the one I ordered so I opened up the battery case to see if maybe the betteries were bad or missing. They has become badly oxidied in the case and so were obviously very old. I pried the suckers out with a screw driver, threw them away (being careful not to touch them with skin in case they were leaking any fluids), cleaned the inside with a clorox wipe, and popped some new batteries in and it has worked great ever since. Give that a try and I hope this helps!

I just changed the batteries on mine and they work fine. I have had them for about a year now.

try removing & re-installing the batteries Make sure they are properly installed, positive & negative direction Make sure the door is closed tight for a good connection

I had the same problem. New batteries did not make any difference. I sent it back to amazon and got my money back. Don't know why they keep selling these, I posted the problems I had with it months ago. I guess Amazon doesn't care. If someone sends it back they refund the money, but many don't send them back and amazon is ahead. George Jensen

My batteries have been working for almost 6 months now. Try using all new batteries and see if that makes any difference

Only thought I have is that you have the polarity reversed on the battery leads. If the leads are correct, the controller is faulty.

Well if the batteries are fresh, and installed correctly (correct polarity), the problem must be the unit itself. The unit's microprocessor might have a problem.

I would suggest that you contact Melnor, the maker of this item. I have NO idea what might be wrong, as long as you've put in new batteries, in the correct direction.

Start with calling the manufacture and see if they can send you a new battery and a new adaptor. If neither of those work, then exchange it for a new set.

Did you put the battery in correct way? Check it,if still not work try in different way and see. Or try new battery and check the connection ( contact) of battery. If still not work then could be problem of the set. My set has no problem to start.

I have been put some new aa batteries in, but it doesn't work. Maybe it is a defective.

Just put them in the charger, side by side. Batteries must be charged in pairs, either two or four at a time, and they must be of the same type. If they are not charging, one of them may be bad. Try switching one of them to find and get rid of the bad one.

reboot...re insert batteries, check their orientation. If all fails contact them cos mine works brilliantly
