Why my Chargers are broken quickly?

If you use a fast charger, or a power charger, that can be the cause of your trouble. I used to charge with different power chargers till I learned they push every battery over its limits. After at least 3 different power chargers and about 100 defective batteries, I now charge my batteries with normal slow chargers. Before I can go on a shoot, sometimes 8 slow chargers are charging a whole night. But since I stopped using the power chargers I never lost a battery on overcharging (actually overheating)

If they are after market chargers then they are probably not putting out the proper voltage... if they are proper chargers it could be the wall plug is reverse polarity... a 5 dollar wall plug tester which looks like a mini charger and bought at any local hardware store can tell you that with its 3 light system.... be surprised how many are wrong in a house.. if that isn't it the charger maybe shot... unlikely two different chargers are bad though... more likely a second hand pad with dead batteries... which means a trip to the repair Depot. But if they are stolen ...

Hi, Check the connections for tightness and use a volt/ohm meter to check for charging voltage. Anywhere between 6v and 12v. If you suspect charger, replace with same kind and Voltage output.
Also check battery(s). replace if dead. After many battery uses. They can have an internal discharge and will not work properly any more.
Good luck.

The batteries have likely been damaged from being on the chargers too long. Try trading a known good battery into the non-working radios and see if it/they will work with a good battery. If so, replace your batteries, and then only put the radios on the charge when they need a charge, such as after the radios have been used 8-10 hours. Longterm charging can quickly age batteries. Life expectancy of a battery is 18-24 months with good care.

Best regards.

NiCad batteries have this problem when they are recharged frequently after being only partially discharged. This is also the case when the batteries are left in the charger continuously - even if the charger is described as being "automatic". I have old 12v batteries that I have been using for 20 years, but I only charge them for a few hours, and only when they have run down enough to be useless. I prevent leaving them too long in the charger by using a timer that cuts the power to the charger after a couple of hours. A couple of years ago I bought new drills and chargers, and believed that the chargers would be automatic and so could be left plugged in. Those batteries only lasted a couple of years, while the old ones are still going strong. I now use the timer for any of these chargers, automatic or not - but I had to buy new batteries first. good luck, Al K

To answer your questions:
1) The light on the charger should come on and stay on, when a radio or a battery is charging. It is not likely all the chargers would go bad at the same time. With this in mind, check your charge contacts on ther radio and the charger. Clean with a pencil eraser if needed. Try charging a battery outside of the radio (if you have a drop-in base), just to see if you get a constant red light on the charger. If not, your charger or possibly the battery is bad.
2) If you have a voltmeter you can check for existing charge in the battery. It will not tell you charging capacity, but it will tell you if it is flat dead or not. Check the date code on the battery. It is a 4-digit number on the back portion of the label in the white area. It will read as 1121, 11 is the year, 21 the week of the year. NiMH batteries have a 2 year life expectancy. And as you indicated, charging with the radio turned on, will age the batteries quickly. It is not good to leave the batteries on a charger with the radio turned on, or for extended periods of time, such as weeks or months. A few days won't hurt occasionally.
3) Lastly, your radios may need serviced. You could have charge/accessory jacks which are worn out, if you are using the wall plug style charger only, and do not have a drop-in base. If they have been anywhere moist they could have grown corrosion and be non-repairable. However, if they are dry and otherwise free of defect they should be repairable. (Current expected flat rate repair is $69 at a dealer who works on this model.)

Have to be careful... many chargers do NOT shut off automatically, and a great many professing to have automatic charge control - don't. Batteries can be ruined quickly by overcharging.

I buy all my chargers on Ebay at a store called Monster Parts. These chargers have extra long cables and good warrarties, all for under 40 bucks. Most chargers are 25-25 bucks.

2 possibilities

Either unstable AC current in the house (Generally, other items that have AC adapters would be failing too)

Motherboard charging Circuit issue (Motherboard replacement)
