Question about Milwaukee 6310 22 18 Volt 6 1/2 In. Circular Saw With Two Batteries, Charger And Case

1 Answer

Milwaukee universal battery charger

My (2) 18volt Milwaukee Tool batteries will not come up to charge.
I believe it to be the charger. While the red light does come on the fact that neither battery will charge make me think its the charger. This all happened recently as I have had no problem then all of a sudden I do. I don't want to buy a charger if its the batts or visa versa. How can I test my charger to see if it is the culprit? Thanks Mike L

    Usually if the light comes on the charger is working. How old are the battery's? There is a date code on the housing of the battery. You can check the voltage in the battery with a volt ohm meter but the charger would require a demand for output to come up to max voltage. Let me know

Check the voltage of the batteries before charging. Place on the charger and wait 1/2 hour or so, then recheck voltage. If it has not gone up, your charger is at fault.

I have 28v milwaukee tool kit and the batteries, both of them, went out at the same time. Strange! Upon charging the light on the charger blinks red and green. The batteries will not charge. Whats up with...

you can try and unplug the charger for a couple minutes and then retry. I have a LiIon at work and sometimes it does it also, if not then the batterys would probably be bad, I would contact and see about warranty replacement for these. They have a good warranty on the newer products.

Milwaukee 18v battery

No, it's showing that the battery is either not taking a full charge or the charger is not charging the battery properly. Find a Milwaukee service center, they will check them and most likely replace one or the other.
