I have a Craftsman battery charger, drill, and a light. When I plug in the charger and insert the battery charger, I get a "fully charged" and "Fully Charged"

Model: BD0607 charger, Charger No., 1425301 Output: 7.2-24V DC 1.6A Battery Charger. I get the lights on both batterys. I find it unusual both batteries would fail at the same time with the same information

Thank you for the update Keith. It is interesting to know that you can repair these if you can get the IC for it.

I did not know that end users could get these parts. Please let me know if you are able to find them.

I feel I should be thanking you, Sam. Knowledgeable volunteers like yourself on websites like this make life easier for a lot of people. Sorry for reviving an old thread, but I felt the need to add my personal experience. You are correct that, even though it's unlikely that multiple batteries would fail at the same time, I too might have replaced my batteries first and then had to spend additional money on a new charger. Luckily I had a second charger to check my batteries. My chargers are identical, except that one was killed by using it with an inverter and the other still works. FYI both of my chargers are Craftsman #1425301, one hour chargers, rated for 7.2 to 24 volt batteries. (Although I've read that this model doesn't work with some Craftsman 16.8V batteries.) My 4 batteries are NiCad, 19.2 volt "EX" type. I came across this thread looking to repair my dead charger. It appears that it only needs an inexpensive comparator IC to fix it. I guess I'll find out once I have the part soldered in.

Thank you Keith for your information on the chargers not charging the batteries.

According to the manufacturer the chargers are hard for end users to check either the batteries or the charger to see which one is bad. They seem to favor blaming the batteries if they are more than 3 to 5 years old.

It is good that you have two chargers that you can use and if the one charger will charges the batteries correctly then it is easier to tell that the charger is bad.

Are the two chargers exactly the same models?

Some of the new C3 chargers will analyze the condition of the battery and try to restore the batteries. Where the older style chargers will not.

I'm afraid the expert reply is likely wrong on this one. I personally have two of these chargers. One will charge my batteries perfectly. The other will light the green light showing they are fully charged when the are not. It's clear the batteries are fine and that one charger is defective. It was likely damaged when it was used with a DC-AC inverter. There's even a note on the cord saying not to use it with an inverter, but it was read a bit too late.

Thank you for your question on the charger saying the batteries are fully charged when they are not.

This is the 19.2 volt charger that I have with a RED, GREEN and YELLOW lights on the charger console.

If the green light only comes on for the charger when you plug the batteries in to be charged I would have to say that both batteries are bad.

It does seem like both of them would not fail at the same time but I have this same charger and I had the same issue with the one battery showing charged when it was not and only the green light would come on.

I am sorry but I think both batteries are bad if the red light does not come on at all.

The problem is there is no easy way for us end user's to check it unless you have a known good battery.

If both batteries are 3 or more years old it is entirely possible that the batteries have aged out.

I hope this will help.
