how do you know if it is the batteries bad or the charger?

I use a voltage meter to test the output of the charger when there is a question of the efficacy of the charger.

Usually it is the battery. Take a battery you know is still chargeable and see if it recharges.

You try different batteries (that you know are good) in your charger. And your batteries in a different charger (that you know is good)

Two questions: is the charger functioning properly? And, is the battery old and no longer able to be charged?

I had this happen to me. Battery charger did not produce a charge of the battery. I got a new charger and everything works fine. I don't know how you would easily ascertain if the charger is bad except to see that the battery is not charged.

I too had issues with the batteries the charger works well but the batteries are sub in performance:

Nope. This might be a knock off styled battery charger, or the batter itself might be broke. Do you have any other batteries to try out to see if it's the charger itself or the battery? Someone you can borrow from? Do some testing to pin down what it is that isn't working here. Good luck.

Sounds as though the charger transformer may be shot, test it with a tester or hold it to your ear see if it buzzes, or feel it see if it gets warm. Check connections also. Assuming of course it is the correct charger for the batteries.JT

You need to test the charger first to see if it's actually putting out a charge. If you have an Ohm's meter or just an "Idiot light" you can do this. Then, if you have a "Batteries R' Us" in your town you can get a new battery. Failing that, They are aval. online. In the past, I've cut the old charger off and using one I have around the house,rewire the battery attachment to an old but working charger. Good luck !

It may not be the battery, it may be the phone, or the battery charger itself. I would have them both checked.

I never had a problem with the battery or the battery charger. If the battery charger is working properly it must be the battery itself. See if you can get a replacement from the seller. Most sellers will accommodate you.

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.

Most likely it is the battery. Generally the charger either works or doesn't. If its the original battery I can almost guarantee the battery is shot.

My charger melted the battery I bought from Amazon. Ruined my drill, so don't buy from Amazon. But to answer your question I would say the battery is bad.

It could be a wire in the charger is broken, and the minimal power you see is what is left in the batteries after they have had time to rest and redistribute their charge.You might ask someone you know to check it with a voltmeter.

It's bad charger or battery. I had that happen too. I returned to the company I got it from on amazon. They sent me a new one that works good

Hello, if I understand you correctly, the output voltage is less than what is required? Maybe a defective battery.. Although, dual voltage rechargeable, 220\50htz, may be the problem. The same with 110/60htz as well. So, it could be the charger. I have had zero issues with mine. Check the component that your using them on too... Hope this helps.

Have your battery & charger tested. If ok, must be a bad connection and should be returned

sounds like a bad battery or is not on the charger properly-ours tells us when charge is complete
