Description

If you’re on a job that requires either 12 or 18 Volt batteries from Milwaukee, this 48-59-1812 charger is what you need to keep your tools working properly. It can charge in as little as a half hour. It has an electronic communication system that monitors how much the batteries have charged. If they’re fully charged or overheating, it will drop the amount of energy expended, keeping your equipment safe and your energy costs down. To help you get a sense of where your charge is, a set of LED lights on the side of the unit indicate whether the unit is fully charged or not. Plug in both your 18 and 12 volt batteries in this Milwaukee charger to see just how much time you can save on the jobsite so you can get your job done. Item is shipped in bulk packaging.

  • Quality product!!
It's a quality product, it has worked very well for me, it charges my batteries very quickly.

  • Brand name you can trust
I bought this charger because it was listed as being shipped in a blister pack/retail packaging as per the photo. That was not the case. The charger was boxed and came shipped in a thin plastic bag. I'll overlook that technicality. The 18v charger worked well. I have not tested the 12v charger but am certain it will work. All in all I am happy with its performance knowing that it has the Milwaukee logo. And the price point was amazing as I could not pass up the buying opportunity. ... show more

  • Great charger replacement for a m12/m18 battery for Milwaukee, this one is built very well.
Shipping took quite a while, and charger is different variant to the one that originally came with my Milwaukee impact driver however it's fully compatible and it is OEM, so with that being said I'm more than satisfied with my purchase, it charges quite fast, lights indicate when it fully charges and its built very well as expected, get this one if you have a m18 battery and lost your original charger ... show more

  • Product ok
Product seems to work as intended. Easy to use, just had an issue with the product listing vs what I received. The product was not in original packaging and was sent to me in a clear plastic bag with scuffs on it despite it being "new"

I used to stress over juggling different battery chargers until I got this Milwaukee Multi-Voltage Charger.
