why is my charger blinking when i have the batteries in?

The charger is identifying whether the batteries are appropriate. It should begin charging in a steady light if the batteries are deemed appropriate. It will not charge just any battery.

I've found that sometimes I have to "jumpstart" older rechargeables in a simple old school charger for a hour or so before they will be recognized by better chargers like this one.

From what I have seen on the internet this unit will blink if it detects a problem with the battery inserted. I presume you are not charging an eneloop battery. It apparently does not like batteries that have been discharged stone cold dead, which in that case you may try charging that battery in one of your older chargers that are not smart for awhile and then this charger may accept the battery. I also saw on the i-net that it did not like some particular brands of batteries.

According to the written text on the charger it states Red Light Flashing - "Reverse Polarity or Battery Fault" So I'd double check whether you connected the leads wrong then get a battery tester to make sure an internal short does not exist. Hope this helps anyone reading this question.

My unit lights up and flashes only when you have a battery in the slot that is charging. When you insert a battery to charge and close the lid, the light for that slot should be flashing until it stops when fully charged. Sometimes I have to turn the batteries around in the slot to ensure a good connection as the batteries can get a little dust-corrosion on them that impairs a good connection.

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

I have one charger that works, one that is toast. When I plug-in the one that works (without a battery in it) the LED comes on green, but flashes red about every half-second or so. If your charger does that, your battery is probably bad. I had one bad battery, and 1 bad charger, and I was going crazy till I connected with someone who had working chargers and batteries so I could do some tests. Hope that helps.

Lights only blink while charging. You might check the surfaces of base and toothbrush to be sure they are clean. Also, check plug. Do you have a GFI that could have tripped?

No, but you can find some videos on YouTube that show off the options. The charging lights should blink letting you know where the charge is out. If your batteries are all but dead, there shouldn't be as many lights blinking. The closer it gets to being charged, the more lights should blink. You can also plug the light directly into the wall using the same charging cable that comes with your light.

When it blinks its charging , when all 3 leds are blinking its almost fully charged and when it does fully charge, only 1 led stays on to let you know its charged

Mine doesn't blink ... it's either steady read (charging) or steady blue (charged).

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.

There is a light on the charger that blinks when charging and is solid when charging is complete.

HI - I am not an expert.....not even a novice....but we aslso bought these and when they are charging from any active USB port (i.e. - is your computer or TV turned on?) --it should blink red as it is charging and then green when fully charged......If not ...it is defective. Good luck

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.

The correct answer may depend on the charger you are using. I bought the Black & Decker L2AFCBST Lithium Ion Fast Charger with Flash Charge. When the green light is blinking the unit is fast charging the battery. When the green light is on but not blinking it is maintaining the charge on the battery. Of course when there is no battery in the charging unit the light is off. With this fast charger, I have never seen the blinking continue more than 3 to 5 minutes. I have a flashlight, a drill and a chain saw which I use the batteries on. This B-D 20v system is excellent in my opinion. Hope they come out with more tools that use them.

I think the easiest way to tell would be to time the charging of a set of batteries that you know is mostly charged vs. a set of batteries that is totally dead. If they both take the same amount of time before the light indicates they're done, then you have a dumb charger. If the almost-charged batteries take much less time, your charger is smart.

The Blinking red lights normally means that it is charging or need to be charged. When finished with charging the red light should disappear.

Blinking red means there's a problem........those batteries goes bad a lot.Red for charging and green for fully charged.Hope that helps...............
