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

Works very well. It charged my 2ah 12v Milwaukee batteries in 30 minutes each. It took a little less time to charge an aftermarket Milwaukee compatible 12v battery. It is not a fast charger. It did get warm charging batteries for an hour which is normal. What else can I say about it? It works with Milwaukee and Milwaukee compatible 12v batteries.

Works as it should very fast shipping and price was good

Works great and would buy again.

Amazing , more than satisfied

Perfect for my use.

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.

Very good price for Milwaukee Genuine OEM charger.

Charges fast

Não funciona no padrão brasileiro

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

Na

Lo necesito para recargar las baterías en el taller, el otro que venía con el juego cuando lo compré lo uso en la casa

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.
