I just got my battery today. I can't find anywhere why the fourth light is blinking when plugged in to charge. Is it defective?

The answer is no you did not get a defective unit. The lights blink while charging, once charging is complete the blinking light stops. Once you have used the battery you will see that all of the lights blink as the battery recharges. Only having one light blink indicated that the battery was 3/4ths charged on the way to full charge. I hope that answered your question. Mark

The topmost light will blink - your battery arrived mostly charged - if it was less charged then a different light would be blinking

No. It Does that while it charges. When it is done, all the lights will go off

It will blink until the battery is completely charged, once the lift is solid then the battery is fully charged, on the first charge especially that can take a long time, it doesn't sound like it is defective at all.

Mine does this but the yellow light is blinking. Don't know why but unplugging it and plugging it back in fixes it... until the next time. :-/

My light (green) stay's on when charging. It goes off when complete. Mine only blinks when the battery is low. It sounds as if your battery might be faulty. I never use tech support on anything. They usually know less about their products than we do!

If you are charging the battery from empty, when you plug it in only 1 light will be blinking. After some time charging, it will be 2 (1 on, 1 blinking), then 3 (2 on, 1 blinking), then 4 (3 on, 1 blinking). After some time all of the lights will go off. That is when it is done charging. As this is a high capacity battery and usb is a low input source, it takes a long time to charge (as would any other backup battery that's charged via usb). Just give it time.

That indicates that it's charging. It will blink faster as it gets closer to fully charged. It will stay solid green once it reaches about 4.2 volts.

Not sure, but I remember that mine blinked in a way that I thought strange. But it did charge properly, so maybe just try it out and see if it works ok!

Sounds like the charger. It's supposed to blink blue when the battery on it is charged.

Well, this is something everyone agrees on. When you attach your device a number of the four LEDs will light up and start blinking, depending on how discharged your device is. You are fully charged when all four are lit up and steady. It really is something I've found very handy.

Hi Eugene, have bought the same unit, no problem so far. The blue light glows whilst it is charging. I would suggest checking you do not have a faulty battery first, all the battery polarities are correct otherwise it sounds like a fault in the lamp controller. Good luck! Apart from being a little heavy and not particularly pretty this is a great bike lamp, actually lights up the road.

When you first place the light in the charger the red light is on continuously. When it is fully charged the light will blink.

According to the manual on page 5 it says the red and green light blinking at the same time means it's balance charging. When the light goes solid green it is fully charged. Have you tried letting it go for a while and see if it goes solid green with no red?

I bought a 1775 today and noticed the same thing. The charging light lit steadily when I started charging the shaver, and when I came back a few hours later it was off. I watched it for about a minute and didn't see it blink. I then started recharging my cell phone from the same outlet to test the outlet, and it's charging fine. I saw a post elsewhere from a Norelco owner who noticed this with his razor, and Norelco's customer service told him the manual was incorrect about the light blinking to indicate full charge. It looks like the same situation here.

Yes. They blink until fully charged then all four remain fully lit. The first time I charged mine, I thought something was wrong because it seemed to take a long time.

When you are charging the battery pack it blinks green while charging. The light will stay solid green when it is fully charged.

The light is supposed to be lit when charging. It might have a faulty or loose bulb. If it charges, I wouldn't worry about the light.
