You asked;
Can you show me a picture of the charger you use in this conversion. And how would I know if a battery has timed out or not.
My answer;
Hi,
If your Makita charger does not start charging a battery but signals a defect when you insert it then it is timed out. The chip in the battery will allow for three default tries before it shuts down permanately. Therefore the phrase "Timed Out".
It has nothing to do with the internal timer in Makita batteries but a default chip that is programed to say, No More. The rest of the circuit board is usually ok and once the battery is rebuit it will take a charge and go back to work with an alternate charger.
The universal charger that is in my offer would perform the function of analyses but when the fault in the battery comes up it will check out just like the Makita charger. The difference is the Makita charger reads the battery for information and will not respond when the chip in the battery opens.
I would suggest that all of your batteries has some internal problem (usually a bad cell) that has caused the battery to fail. Now if the chip has been tripped three times it can't be reset and your Makita charger will never recognize it again even after the fault has been neutralized.
If you have not tried to charge the batteries after the first fault the batteries could be rebuilt and then again recharged on your Makita charger. If the chip has been tripped then you have to use a universal charger after the battery is repaired or rebuilt.
If you would ship me the batteries I could run the tests to determine the problem with the batteries and if the chip has tripped or not. In either case the batteries can be rebuilt. The only question then is how you are going to charge them. The options are all better than tossing the batteries and replacing them with new.
I am going to send this message now and in a few minutes I will send you the link where you can see the charger.
I have a number of these units out and they are working great. This charger will work on any 18v Lithium Ion battery.
Thank you,

Milwaukee V18 and V28 Lion Tool Batteries
You asked;
Can you rebuild 28 volt lithium ion Milwaukee batteries?? If so, how much??
My answer,
Hi,
If you are talking about the V18 or V28 Milwaukee LI-Ion battery it is not the question of can I rebuild but can I get the cells to do it.
For a short time the cells were available in small numbers but now they have been classed in such a manner that they will not import them into the USA.
I have three (3) V18 in house that can not be rebuilt.
I have a customer that has used the V18 for some time but his usable batteries are dying out so I convinced him to go back to the Ni-Cd battery which we can rebuild in pretty substantial units.
I am not aware if they built a 28v Ni-Cd to work with so I would have to research that before making any suggestions.
The tools that use the V series battery are excellent and most customers do not want to dispose of them just to update to the newer battery configuration.
What is available on the market for purchase are, I believe, the last of the line. When they are gone then a battery option will force everyone to change.
I hope this helps.
Thank you for asking,
