Been charging BMW for 7 hours and the charger still shows it in the Charging Mode. If I manually cycle Mode button it goes to Green Full Charge ?

I don't know the answer to that question because I don't know if he is hooking it up properly. Once the equipment is hooked up you have to cycle the mode button to the appropriate symbol (for a car it is the battery symbol). Then let the car charge. It is not for use on a dead battery as far as I know but only to maintain a charge on the battery while car is not in use for long periods of time.

I have had the same experience. I have found that if I unplugged the battery tender from the power outlet and then plugged it back in it would recycle and perform as intended. Have you attempted to start your vehicle? I'm sure your battery is up to snuff. The other aspect is that this is not a battery charger in the common term. It is a battery tender and will cycle in and out. The purpose is to maintain the battery at optimum charge without overcharging. I keep four vehicles that I don't use often on these tenders constantly and have never had a problem with my batteries. Great piece of equipment. I have had the same experience.

Depending on the battery condition the charger may take more than 7 hours. The last amount is at low current to fully charge.

Sometimes the charging mode is down to a trickle, but not enough to change the light status. Manual operation will trip the circuitry. Are you sure that the battery type selected accurately depicts the battery in the car? We have over over 30 of these units in operation and never seem to have this problem. However, it your situation continues, and it bothers you, contact Ctek and they will either repair your unit or replace it. They are very easy to deal with and very helpful!

When it is fully charged the light turn into green and stops. I don't think there's any problem in living it more hours connected... I have forgotten it some times charging of r a day or more and nothing happened...

The charger I got with mine had a little light on it that is red when it is charging and turns green when it is done charging.

I don't have this problem. Make sure the light on the charger turns from red to green. I haven't clocked it but it takes like 10 hours.

My battery came charged but not fully charged. It would start the bike BUT when hooked to my charger the "red" light did NOT immediately go green. I charged it overnight and haven't had a problem since.

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

There is a charging LED light on the charger that will be red when you first plug it into an outlet. It turns green when the battery is fully charged, about four hours or so. You should unplug it when it turns green and not leave it plugged in indefinitely.

It's probably not your charger... My daughter used hers for 5 minutes and it never charged again. The whole bike is not what it was supposed to be..

I haven't used my new Charger long enough to answer correctly, but it has a box at the bottom that tells you when the battery is full charged, it may turn green, but I cant verify that yet. sorry.

No, it is a trickle charger (compared to a "smart" charger that automatically turns off) and will overcharge. Please read the instructions, which clearly state not to leave it charging for more than 8 hours. Only charge until the light turns green, then stop. They also state to recharge immediately after use, and every 30 days if not used, to keep it topped up. Apparently they don't want you to leave it in a discharged state.The battery seems to be the weak link in these rather crappy quality lights. I would do everything I can to follow the instructions and not do anything that might damage the battery or shorten its life...

I left mine on charge for several days. The light never turned green. The light on the charger went out, and now nothing works. Evidently, at these prices they do not include technology to stop the charger from over charging the battery. I will be attempting to return mine forthwith.

Hi, When the light is green its not charging any more, Battery is at 100%. its supposed to start discharging.

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.

It's supposed to turn green when is fully charged! I don't know what's wrong with yours ! You may need return it!sry

OK Susie P., so you've used the battery until it is completely exhausted and now it won't recharge, correct? If you have checked to make sure there is power to the charger, the charger light should glow red when no battery is inserted, red while the battery is charging (a couple hours) then green when the battery is fully charged. If the charger glows red and you never get to a green light, then the battery is defective and should be returned for an exchange/refund.

I don't have an answer for you, but I did notice the same thing. I have been charging my deep cycles on standard. I am a little disappointed that it does not offer a separate deep cycle charge as this is my main reason for a new charger.
