Having purchased both the M12 drill and Hackzall kits, I've had 3 of these chargers in my posession. Only 1 worked perfectly out of the package. The first charger (with the drill kit), thought both battery packs were defective. Amazon sent me a new kit - with it's charger, all battery packs charged fine. Wanting more batteries and another charger, I ordered the Hackzall kit. Inserting the first battery to charge again lit the faulty pack lights. Looking into the charging well, one of the extra 3 sensor contacts was bent down flat on the bottom of the well. Bending it back got the charger working. While it's great that it was a simple problem, a factory fresh charger should not have a problem with functioning.
When I took the charger with the bent contact apart (T10 security bit), the inside of the charger seemed well designed. The case seems to be made of polycarbonate and the circuit boards are the high quality glass variety. There is no potting compound over the circuit parts like in the V18/28 chargers though. Also, the plug on the M12 charger is not a pass through like on the V18/28 chargers.
If Milwaukee sorts out the bugs and sends you a working charger, it's probably a 5 star device (it even has slots on the back for wall mounting!). Milwaukee 48-59-2401 12-Volt Lithium-ion Battery Charger
I bought the 2401-20 driver drill. Nice, convenient tool. It came with this charger. Unfortunately the charger died (similar symptoms as another reviewer here). What really frustrated me was the warranty service. I called my local serivce center and they asked me to produce the receipt. Remember that this product has a 5-year warranty, and has been in the market for <1 year. I'm basically S*O*L unless I can produce the receipt. Very un-impressive for a company that used to produce the most rugged tools on a jobsite.
I bought this charger along with a new battery. Charges up the battery real fast, but the original battery I had, this charger shorted it out or something. Never could use it again after I one time put my original battery on. The battery I bought along with this still works great and charges up fine. Not sure what the problem was, but giving you heads up.
Two years ago I purchased the M12 driver kit for light home use. A few weeks back the charger failed (Red and Green lights blinking). But the batteries test OK. The charger reads 14 volts and then drops to 0 within 20 seconds. I ordered a replacement from Amazon. That one proved to be defective. They replaced it. Again, that one was also defective. Then I had a local service center return it to Milwaukee. Then that replacement was also defective. Now I wait for my fifth charger. In the future I'll be rather reluctant to buy a Milwaukee tool. However, I am not disappointed with Amazon's service. - Chargers - Cordless - Lithium - Cordless Tools'
