I would make sure the batteries are both positive up in the charger unlike when installed in a remote in alternate directions like with most applications requiring batteries. You might also try another outlet to insure it is not the outlet causing the problem.

I did not have this issue. Other have recommended checking to make sure you have the batteries in the charger correctly (+/-). If this does not help your issue I would contact Amazon and arrange a return/exchange since they are most likely defective. I recommend an exchange since these are otherwise decent batteries.

Try moving both batteries to the other side of the charger. If you had them on opposite sides or in the middle I believe the left side as you face it plugged in is the side to use for less than four batteries.

Had that happen once. Of course, always Make sure the negative end of the battery is inserted into the spring. Never try to charge it throughout the night. It messes up both charger and battery. It burns the cells of the battery if kept long in there fully charged. The charger you have takes a while to charge. It is low voltage so not that much juice is delivering into your battery. This is a very good battery I used it for my vaper "ecig" and can last for a few days without charge. Hope this helps.

With mine, all the green lights are on when it's fully charged, but now always. I have no idea what the red light means. It may be just for show. I wouldn't buy another one of these, though. It works 95% of the time. Sometimes I pull the battery off after a few hours, and it hasn't charged. It didn't come with any type of documentation.

i was having this issue as well...but i read that there is a RED light that turns on when the battery is charging...so i played with the USB that is plugged into the unit, and found that the red light turns on when its plugged about HALFWAY in. i checked, and it IS in fact charging. try adjusting the B side of the USB (mini part thats in the actual unit) before you return it.

The first time I tried to charge mine it did the same thing, I moved around the charger connection to get the red light to stay on, you may have to unplug an plug in again to get the red light to stay on. The other issue that causes problems is the delay between getting a good connection and when the red light actually comes on. Plug it in and wait a few seconds to see that the red light comes on and stays on.

Unfortunately, I have the same problem and no amount of charging is fixing it. It almost feels like there is actually no battery inside, or it used up its number of possible recharges. Returning it to Amazon. Will try one more time to order this thing.

I think I solved it. Once you clean it as the manual says you need to reset the system. With it plugged in but NOT turned on, put a paperclip or something in the reset button and press the (I think) Timer button. Should work then. The reset procedure I just described is in the manual right after the cleaning instructions.Thats funny V. Montez, I did the same thing - put it away for a cpl months and finally decided to tackle that damn blinking red light. Its all working well now!

Dear Kenneth, Thank you for your message. There should be a built in charger in your system that is charging the battery. If you have the battery for a long time and it is not working, most likely the problem is with the battery not the charger. If you are sure that the issue is with the charger, then most likely you need a 12v 2amp charger. Unfortunately I wasnt able to find one with the model number you have provided us with. Please let me know if there is anything else I can assist you with.

I can only guess at this but I would look at the charger itself. If the red light is showing when plugged into outlet and it does not turn green, then I would assume you would need a replacement battery. If light not showing then I would purchase the charger. However, I had a similar issue with one of my sweepers. I happen to have two sweepers so it was an easy check for me. I thought the battery was not charging because I could not get the sweeper to work. The battery light on charger showed green or charged, bur when I plugged it into the the sweeper, it would not work. Turned out that the sweeper itself was not working, the battery and charger were just fine. I can only guess at this but I would look at the charger itself.

Hi Thomas Q., I ordered mine and plugged it in and I believe it has charged the batteries. I will check tonight when I get home to see if they were fully charged and let you know. I do know the charger red light came on when I plugged it in which should signify it is working and charging.FD

Make sure your batteries are correctly installed and then plug it into the provided charger. I charged mine when I received it. Also check all battery compartment connections. I had a slightly bent connector. If it fails to work after that I would defiantly as to exchange it. They really are great headlamps. Despite some of the minor issues.

I have a problem, that might be related and I wanted to ask people as well. When I put the battery in the charger (I have two), most of the time, even though the battery is empty, the charger shows green light and does not charge. I have to put the battery in slightly elevated angle and push on it and then it will start charging. So maybe your batteries were not charged at first place. Also happens to me, that the batteries discharge if not in use for 2-3 days, so before use I always recharge.

when purchasing new yes,however when i purchased a refurbished one , i did not receive a instruction book or a charger and was very upset !1

The battery is kinda hard to get in the charger. If you get it in correctly you will see what looks like 4 small batteries. If any one of the batteries are flashing it's still charging. When all 4 batteries are on and not flashing the battery is charged.

Probably not the answer you seek but my suggest is to call Home Depot or Lowes. Both stores would know if the correct charger for the battery as well as if this is right or wrong. All Dewalts that we have ever owned always blink red while charging and then stay green once fully charged. God Bless You with a fast solution.

About 2 months ago I purchased 18 of these units. When charging them all, I initially found that only 4 of the 18 green lights on the chargers came on and the rest remained off. However, I verified that although the green light was not on, the battery was still being charged as expected (the charger was working fine, but the Green LED just wasn't working). As time went on more green lights would come on, somewhat sporadically it seemed - but all the chargers were still charging. It's certainly inconvenient. As a result, I measure the voltage on each battery after charging to verify that it reached capacity. About 2 months ago I purchased 18 of these units.

The charger did not work for me. My batteries were completely discharged and the charger must detect X amount of current before it will activate. Most modern chargers are similar. That having been said the charger must be attached to the first and last battery in the battery bank. Posative to one battery and negative to another. Look at your battery bank. you will see that the batteries are connected together positive to negative. 8 volts each x4 to get the 48 volts. Look for the battery posts that are connected to your charging plug in, and or that have wires going to your speed controller or motor. That is where you want to attach the charger. It should work fine. The charger did not work for me. My batteries were completely discharged and the charger must detect X amount of current before it will activate.
