[P107 low voltage and red light blinking]

How many chargers do you have? I run into this problem once in a while, usually when I just used the battery and put it on the charger. What works for me is putting the battery on a different charger, but I have three chargers so it's easy to do.

 

 

If the battery is showing a really low voltage it may be past the ability of the charger to "read" it, which means it's dead. One trick you can use is try to charge it with something else, any DC charger of comparable voltage will have the ability to send amperage to the battery. Another brand of charger, a car jumper pack or a Battery Tender, or similar, if you have one, may send enough amperage to the battery to revive it. Then you can charge it as normal on the Ryobi charger. Could be as simple as the charger just being finicky with that particular battery. Can't hurt, if the battery is dead you aren't going to make it more dead.

 

 

There is a trick with "dead" NiCads, don't have a clue if it would work with Lithiums, never tried. But, you used to be able to put the NiCad on the charger, then unplug and plug in the charger several times in rapid succession and the battery would start charging again. I did it many times with my old NiCads, and it actually worked pretty good to revive them and keep them going...ultimately it stopped working but I got a few rounds of life out of the batteries before they died completely.

 

unfortunately I only have one charger.

And yes, actually I want to try it. But I don't know how many volts when fully charged and how many volts if it needs to be recharged.

Can you tell me about it?

Because I get 18V in multimeter, you can see it on video.

What it means under volt and must be recharged? Or defects on the pcb?

Did you call the company line and see what they would do for you? That's the first call you should make,

 

If I did that, they would check my battery. But I was a different country.

Usually your at the point of no return on a battery like that, like mentioned above warranty would have maybe worked but you'd need to replace the cells

I was not going to return. Due to shipping problems and different countries. So I want to solve this problem before buying a new battery

I have p107 lithium battery 18v. Now i can't use it because if i charging it will be testing mode "red blinking". 

I showed my problems in this video. 

 

 

Thanks for helping
