If you have the skill to determine the transformer input is open, I would expect you have the skill to replace a transformer. Based on this assumption: determine the input voltage (120 vac?), determine the output voltage (14 vac?), determine the power requirements (output voltage times the charging current), find a transformer at www.digikey.com or www.mouser.com or www.newark.com.

SOURCE: My 12 volt panasonic cordless drills charger

Unfortunately, Panasonic uses a unique profile on their battery packs that allows them to fit into Panasonic chargers. So trying to find another brand charger won't be possible. At one time, DeWalt made a really nice Universal charger that would charge literally any rechargeable battery made, but it cost a small fortune and they stopped selling them after only a year.

I would suggest that you call the customer service number and see if they can provide you with a local service center that can repair your charger for you.

http://www2.panasonic.com/consumer-electronics/support

You can also check the Panasonic site to see if they'll help with a repair or possible replacement under warranty or customer satisfaction, etc.

Sorry to be the bearer of not so good news, but hope you find this Helpful and best regards!

SOURCE: charger died.

It is usually a current limiting resistor anyway... so I would think that about 100 Ohms should be all good, you generally need about 250 - 300mA to charge ya batteries. It is simple Ohms law calculation.

How to wire with a 12v supply from cp charger

If your question is about using the transformer (charger for your cellphone), the answer is that the transformer is made to convert (110-120 volts) to the required DC input for the device. You can't use a cellphone charger (typically 2-5V) to charge a device requiring 12 volts. The voltage converted is in the plug itself.

yes
but battery charge voltage has to be 14.5-14.8 volts to charge a battery
batteries are known to be 12 volts but in fact at 2.2 volts a cell they are 13.2 volts capacity so 13 volts will not charge a battery

I have a question about a freedom marine 25. If the voltage into the inverter charger is not at 125 volts will the system not charge properly?

I don't know if i'm not reading your question right...but an inverter is an equipment that takes 12 Volts DC and transforms it into 120 AC. The input is a 12 VDC not 125 V.

APC BACK-UPS ES 500VA fails to provide back up during power failure

Get APC Powerchute Personal Edition for free and run it. If it says your battery isnt charged, check its voltage disconnected. Charge it with a car battery charger and see if its still a good battery. If not , replace it. If the battery is good, then check the charging voltage. Should be about 14 volts. if not, check the small transformer on the main board. Should be 120 in and 17 to 18 out. 4 diodes in a bridge for charge. The input to the transf has small fuse into it alone.

My vector vec157 will not charge on 120 volt. It works on 12 volt

If you light is charging when you use the 12v automotive charger but not when you use your AC power transformer, my thought is that you might have a problem with your AC charger, not with the light itself. I have AC/DC transformers from the 1970s that still work fine, but I have had numerous modern AC/DC transformers burn out on me in recent years.

One easy test is to use a multimeter to measure the output voltage of your wall charger. Place one test lead on each of the charging terminals (i.e., one inside the barrel and one outside the barrel, if you have a standard coaxial charging port) and check the DC reading. If it's zero--or anything less than 12 volts, actually--the charger isn't working correctly. The problem may be a torn or cut wire or something actually inside the transformer.

Replacement chargers can be found at Radio Shack and other stores. You may also be able to score a cheap replacement at a "dollar plus" store or even at a second-hand shop. Make sure that the terminal polarity is correct on your replacement charger or else you'll fry the batteries in your light.

Good luck!

I have a Shark Clean Sweeper and need to replace the 7.2v charger. Where can I find this.....I'm running into blank walls.

Actually, the charger for this 7.2 volt machine probably puts out nearly 9 volts to push the voltage into the battery. It shouldn't hurt the battery to use a 9 volt charger as long as the connectors match up. There are a lot of devices out there now that use 9 volts, so it shouldn't be too hard to find one that would match up with the connector on your sweeper. All the charger/transformers tell the input they use and the amount of voltage they put out.

Battery charger model 1400666 not charging The red led is not on.this is a 12 volt charger.

I have two 18volt chargers doing the same thing. I have had them apart and it seems to be the transformer not pushing any power thru. If you can find a transformer that fits and has the right voltage that should fix the problem. From what I can make out if you leave the battery in for too long on charge it cooks the transformer. Hope this helps
