I have an Allied 18 volt drill driver. Can I use this charger to recharge the battery?

Answer

I don't think so. If the battery on your, "Allied", 18 volt drill driver doesn't have an, "M", on it; it may not fit. I never heard of Allied, so I would not buy this charger. I would check with Home Depot if it sells a universal battery charger just to be on the safe side; and not spend your money on something you may not be able to use. Sorry I couldn't help. Good luck.

The Milwaukee M12 and M18 Li-Ion Charger is a good charger. I've had this for about three years to recharge my 18 volt batteries. It doesn't get hot when charging, the cord is nice and long, it can be mounted to the wall (which is what I did in my shop). I haven't found any failure points or wear points after three years of use. It charges my 1.5 Ah 18 volt batteries quickly in less than a half an hour. The light indicator is great and easy to see; green when charged, red when charging.

Best 18v AND 12v charger!
Milwaukee has more advanced charges like the sequential or even the radio but for a standard charger this things is great especially if you have 12 and 18v like i do. The indicators are simple to read and understand. no blinks to count or understand. green is done, red is charging...simple! I've had other from all kinds of tool manufactures and this one is my favorite standard charger. I have one in the car for work and another in my workshop on the wall. I have 4 in total.

Don't buy this charger. Failed after 2 months.
This charger came with a M18 compact brushless 1/4 in. impact driver with 2Ah battery. I have used this charger about twice a week for the past two months. The last time I used it, it charged my M12 battery, but eventually the light was off on the charger. Tried a new outlet, tried different batteries both M12 & M18, still doesn't work. There is no fuse to check accessible to the consumer without taking it apart.
