Milwaukee Genuine OEM 48-59-2401 M12 Lithium Ion 12 Volt Battery Charger w/LED Indicating, Red

Great buy, Very Durable. Charges fast.

I have only one Milwaukee tool and I need a charger for it. This charger if the bill!

Good

Worked perfectly right out of the box. The Mikwaukee M12 charger I had crapped out. Bought this one for a fraction of the price. Could not be happier.

I’ve been buying Milwaukee for years; it’s very high quality and gets the job done when it comes to charging the batteries.

This is a technology and product safety situation that depending on how the designers implemented the features. I don't know what a solution might be; that's up to the designers of the batteries. The Charger works OK (see below) but it also won't charge 2500mAh 12V Replacement for Milwaukee M12 Battery. From the construction I'd say that both batteries came from the same OEM supplier. Both were bought from Amazon within the past month. The reason seems to be a charger safety feature to prevent trying to charge a bad battery. More on that later. When plugged into the charger, nothing happens: No steady or flashing indicators With other equipment I use for my electronics hobby, these batteries have been discharged and charged many times. That to condition them for maximum charge. I use a ZB2L3 discharge controller and a stand-alone Li-Ion/Li-Po charger. They have also been used and work OK in a Milwaukee M12 drill. So I'm confident they are good. But they would not charge in the same type of charger that comes with the drill kit my In-Law has. The stand-alone charger I have won't charge a bad battery either. Unless the Milwaukee charger circuits detect an acceptable voltage level, nothing happens. The sensor uses the LED supply voltage from the 3 terminals to do this. If that voltage, tapped from the battery cells, isn't within the required limits, charging won't happen. Apparently, the batteries mentioned above do the 3 terminal arrangement differently than the batteries that do charge. DON'T DO THIS AT HOME How do I know all this? By inserting a thin plastic strip to cover the 3 terminals, a partially discharged battery charged OK. All I'm able to measure is the voltage at the 3 terminals. It seems to be OK relative to that needed to light LEDs. But...How would one know before hand? Amazon? UPDATE: 22 Feb 2020 I've discovered the reason for my charging problem. My stand-alone charger charges to about 14.2 V. The Milwaukee charger only to about 12.6 V or 3 x the nominal 3S 18650 4.2 V per cell full charge. Trying to charge a battery with more than 12.6V volts on the terminals must look like a failure to the Milwaukee charger and it shuts down to prevent damage. I'm still using my stand-along discharge controller and charger and making sure the end charge voltage in no higher than 12.6 for both the 3S 2.5A and 2x3S 6A battery packs.

I had lost the original charger for Milwaukee portable flashlight and battery. There were other inexpensive options available online, but I wanted the Milwaukee brand. It came on time as was promised. Packaging was good..... and charging the battery perfectly. No complaints here!

I have a heated jacket and needed a charger for my battery. This is compatible my Milwaukee battery and charges it very fast. There is no noise when using it. It is a good value for the money

Não funciona no padrão brasileiro

Buena

Na

Desconozco so hay un empaque para el cargador, llego en una bolsa generica. Vino con su instructivo y parece nuevo y original. Funciona sin problemas.

Muy bueno solo que la batería se pidió y demoro mucho para llegar y mejor la cancele
