i put the battery (new) in the charger. a green light comes on quickly then goes off. no light. what does this mean?

I'm not sure. Usually, the light is orange, then turns green once the battery is charged. The contacts are particular, but if they're lined up, and you're still having the same issue, I would think there was a problem with either the battery or the charger.

I rather agree with both the previous answers. When you say the light goes quickly from green to off, do you mean immediately? If so, I would check that battery in your phone to ensure that it is fully charged. I have had similar experience with a battery I was unsure if charged or not. Even so, the light would turn green, then remain orange perhaps a minute, then turn off as it was fully charged to begin with.

Light on charger is red when charging, changes to green when done. Once green, don't let it overcharge too long.

Try reversing the way the battery fits in the charger. Turn it updside down and put it in and it will charge. Topside will only display a green light and will not charge it. Hope this is clear enough!

Can't tell if you have the same problem but a note to all owners: After using my mower I plugged in the charger but the charger light stayed green even though the battery was discharged. Contacted Customer Service, who said take it to a repair shop. THEN, I read, in very fine print, that the light is green if charged OR if disconnected. So, I jiggled the charger plug (at the mower) and the light changed to red. Problem solved.

My charger's green lights show if the batteries are fully charged, or if I don't have any batteries installed in the charger. The red lights come on when the batteries are actually receiving a charge. Make sure you have fully removed the protective plactic that covers the new batteries when they are shipped, or your charger will think no batteries are installed, and the lights will stay Green.

There is only one light in this charger. When you plug it into the device, it will turn red and then it will change to green when charged. Check the side once you plug it in. Took me a couple of looks to make sure it was functioning - I did not think it had a light myself.

There is just the 2 red LEDs and 1 green one for the "charge level" indicators, correct? If so then seeing both red and the green LED come on when you push the test button does hint it is fully charged. If this is the first time you've charged it (where it can take 24 hours to charge), then I'd double check that it's full by pulling the plug on the charger and then push the test button again after 30 seconds. You should still get the 2 red LEDs, but probably not the green. If you have a volt-meter you can also check the battery voltage on the jumper cables, full is ~14V with the charger plugged in and without it plugged in it should drop to ~13V and hold there. If you suspect the battery being bad, then the way to test it is with a known load and see how low the voltage goes. For example, I plugged in a spot-light that pulls ~4 amps and a good battery had the voltage drop to 12.4V instantly and very slowly dropped the longer I had it on (like after a minute only dropped to 12.3V). A bad battery instantly dropped to 11.2V and within 30 seconds went down to 10.5V. That's how you can tell if it's really bad.

I just plugged my charger in with two batteries. Light is solid red. Will turn to green when charged

From what I understand from reading the owners manual, that indication is the chargers way of telling you that the battery is very discharged and is only at about 25% of its capacity. The LEDs are supposed to blink, not light up solid, as the charger is charging. If there is nothing wrong with the battery, the charge level should start going up after a while and in a few hours, the LEDs should read at 100% (solid, not blinking, red, red, yellow, green LEDs). I hope this helps you Mary! Michael R

In fact, at the time it starts to charge (with battery inside), it must be in red mode (the charger light), but when it is full charged, the same light changes to green. If it begins in green you have to check if the battery is in right position, I mean, the connectors have to contact ones to each others (charger - Battery). If not, please adjust them until they contact together. it can occurs frecuently. good luck.

There is a charging light that stays on while the battery is charging; the 'maximum charging' light does not stay on the entire time on mine, and mine works fine. So - maybe you should have yours checked out or return it..

When you plug in the battery the little green light will come on to let you know it's charging. When that light has turned off then the battery is fully charged and you can put a new one in.

definitely NOT normal. Your charger should charge the battery and you'll see a blue light.

I don't think it is. I charged my battery using the charger that comes with it and the green light stayed on even after 5 hours. I then plugged that battery in to my other charger and it showed that it was fully charged. The drawing on the charger does look like the light should go out but it appears it doesn't.

First is the battery new or relative new? If the battery is older it could not be taking a charge, the green light will stay on until the battery is charged. Second, if the battery is relative new and the charger has been on it for 12-24 hours and still green then the charger most likely is defective. You will have a better idea than I because of the age of both the charger and the battery. Note: The chargers do go bad after just a few years and you will get the results you explained. Will be glad to help more if you wish to give more information due to age of each item. Of course it would be an opinion but an educated one, I am a certified electrician. Maybe this will help..... either one is bad news because you can purchase the whole unit as inexpensive as you can purchase a Charger or Battery!

Charger light changes from red to green, IIRC. Don't have it with me right now. *Might* be printed on back of charger...

is the green light on the charger on after charging battery. if not battery not taking full charge, battery on my u12a stopped taking full charge after 3 charges and green light would not light,
