After my headlight battery went dead the first time, I connected it to the charger. The LED on the charger has been red for 5 hours. What's wrong?

Nothing wrong, the first time my battery was 8 hours connected until the led turn green.

Red means it's still charging. Mine sometimes needs to be left charging overnight before it turns green. Not sure if that's the case with yours but it's worth a shot.

The battery was low in charge, and the charger is not very powerful. Mine charged with the indicator red for about that long when I first used it. I'd give it at least 10 hours to turn green unless the battery gets hot (in which case its bad and needs replacement).

My LED is red when charging then turns off when the battery is fully charged.

It needs a new batttery, or the charger is bad. Check the volt output on charger.

sorry I had to return this item as, I charged it for almost ten hours and still nothing turned on. Also I never noticed a red light I believe that the one I got was ruined.

The only suggestion I can add is to make sure the charger is working properly. It seems obvious, but it's one of those things we take for granted. It happened to us this spring. The charger's plug had come loose from a power strip. If that's not the problem, use a voltmeter to check the power output of the charger and the health of the battery. If that all checks good,it's either the associated wiring/switches or motor. That would surprise me. My bet is on the battery if you've had it for three years or more.

Something must be wrong with your charger. Mine works fine. After use I repace my unit in the charger and the Orange light will turn to green (indicating a full charge )after one or two hours. Ready for use again. I have had no problems with my unit and use it for 30 to 40 minutes every other day ..Kendra

Probably your battery is dead and cannot be charged. Usually, the 25% LED should be solid and jump to the 50% LED (flashing) and so on until all LEDs are solid, then the battery is fully charged.

Eventually after the battery is fully charged the light goes to a steady green. If the battery is defective, a red light will indicate that. This charger is a little more critical of the overall health of the battery. Some people have commented that the charger says to replace the battery were other chargers say it is fine. I have only had this happen to me one time and I believe the battery probably should have been replaced.

My red light went off after 3 min. of charging. I can't tell if it's charged or not...

Tony,I have not had this issue, after the 23 hours of charging, when you check the battery indicator lights, are all 3 lit. if they are, there is no issue. the battery is at full power. Otherwise run the battery until fully depleted then recharge. usually they take a few times to come up to full power. Hope this helps!

Well, when I tried to charge my battery, it immediately stopped. The red light on the charger went off after two seconds. So, I just used my old charger. The old one worked fine, the red light stayed on until the battery was charged.

Here is a link that fully answers your question. http://www.batterychargers.com/Documents/0099001192WB-00.pdf Basically when the YELLOW LED flashes, the charger has aborted the charge as the battery may no longer be capable of taking a charge and must be replaced. That said, it is a good idea to reset the charger and try the charge again before replacing the battery. To reset the charger merely unplug the charger from the wall, wait a minute, then replug it back into the wall...If the light stays SOLID ON and yellow, then it is charging...it may take a while...if it faults out again and starts flashing yellow again, then replace the battery. GOOD LUCK. and I am most sorry for your the loss of you husband.

This is just a guess, but LED light technology is such that the light will still work even if there is just a little power remaining. There just might not be enough power left to charge your device. It's possible that you just have to re-charge your battery by plugging the micro-USB cable into the battery and connect the other end to a power source. If that doesn't work, contact the manufacturer.

I've noticed the same thing. After a short time they are completely off and do not drain the battery. I don't know the reason for sure. My theory, LEDs have a broader amperage operating range and pick up the residual in the system for a short time. Just a theory.

It might be that the charger died. I have had that happen. They don't last all that long. About as twice as long as the batteries in my experience. Do you have another charger to test them in. Maybe a friend has one.

Sounds to me like you may have a defective battery. Only sure way to find out is to try another one or ask a dealer (if you have one in your area) to check it for you. Thats the best I can tell you as this is the first thing you should always check. Its also possible your charger is not up to snuff. Good luck. -js

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.
