Is the charger light supposed to be blinking red when it is charging? I've had my batteries in for about 4 1/2 hours.

The charger light should be a solid red (on mine anyway) and then it will turn green when fully charged. It does take about eight hours to be fully charged so don't be alarm that it takes so long (not very convenient). Also, your charger light may glow green with the battery inserted even though the charger is NOT plugged into an outlet. 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.

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.

The light is red when charging. But if it doesn't hold the charge perhaps it would be best to email the seller with this question.

I'm pretty sure it's not, mine started off red, then went green when charged. After 2 weeks of use it blinked red then stopped working altogether, I'm pretty sure one of the inner connections is loose/broken.

It has a blinking red light when the battery gets low. Also, when you charge it, the red light comes on. When fully charged,the light goes off.

It is normal when recharging. The length of time it blinks normally depends oh how long it's been unplugged. As mention below no true way to measure.

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.

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

Seems like when it's fully charged, the blue light continues to blink. It would be nice if it stopped blinking to let you know that it's finished charging.

The charger should blink when plugged in. We use our phone cord and plug to charge it. If it charges you turn it on by the button on front it should turn green. Personally have never had a problem with any of the ones we bought.

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..

Red light just shows that power is on. When the light is blinking it is charging. It will be steady green when it's fully charged.

Mine displays a Red light on the inside, when charging. Once fully charged the light simply goes out (not green).

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

When you start to charge it a small red LED on it starts to blink. When it is fully charged it stops blinking. I haven't had mine long enough to answer your "how many hours" question. If the answer is not in other questions on this page, there is a similar device on Amazon selling for about $11. Somewhere on either that device or this one, someone said how long their's lasted on one charge. The time on the $11 device is probably the same as this one.

I just got one and the user manual is ridiculously lacking in details. So humor me...how do i check charge status? I turned it on and all lights blinked once. I plugged it in the wall and only 1 light is blinking. How do I know when it is fully charged?
