Not scientific, but wanted a general idea how well these Waitley batteries would handle compared to my genuine Milwaukee M12 3Ah battery. All batteries were purchased at the same time, but no idea how old they actually are. I also don't know the specifics of the batteries so I don't know what the curves look like, but here are the results.As a note, my application only draws about 3A so these batteries will work for me.Fully charged with genuine Milwaukee charger.Fluke 36 clamp meterFluke 117 MultimeterLoad, 90W 12VDC radiator fanBattery 1Milwaukee M12 3Ah*Fully charge*10 minute restVoltage before load: 12.21VDCInitial Load: 7.9ALoad at 120 seconds: 7.2ATime: 120 seconds*10 Minute restVoltage after load: 11.98VDC~Voltage drop: .23VDC~Amperage drop: .7ABattery 2Waitley 3Ah*Fully charge*10 minute restVoltage before load:12.39VDCInitial Load: 7.5ALoad at 120 seconds: 6.8ATime: 120 seconds*10 Minute restVoltage after load: 11.92VDC~Voltage drop: .47VDC~Amperage drop: .7ABattery 3Waitley 3Ah*Fully charge*10 minute restVoltage before load:12.25VDCInitial load: 7.2ALoad at 120 seconds: 6.7ATime: 120 seconds*10 Minute restVoltage after load:11.83VDC~Voltage drop: .42VDC~Amperage drop: .5AFor the price of a $70 Milwaukee M12 3Ah and ~$10 each for these, they a suitable alternative.Edit:Tested again.Battery 2Waitley 3Ah*Not fully charged*10 minute restVoltage before load:12.1VDCInitial Load: 6.1ALoad at 12 minutes: 5.3ATime: 12 minutes*10 Minute restVoltage after load: 10.7VDC~Voltage drop: 1.4VDC~Amperage drop: .8A

Works great fair price

This is the second set I’ve purchased. It’s nice to have a second set on the charger, while using the other set. The fit is decent and stay in the tool, but not quite as good as OEM, but at this price point, I’ve been more than happpy with charge speed, durability and functionality.

great batteries for a milwalee M12 driver

Don't know for sure if they last as long as the originals, but at this price I can have a box full in my truck ready to keep me warm on the coldest days.

Work as advertisedWork with all my Milwaukee tools with M12.

Snaps in like the Milwaukee battery ,will see how long the battery last.

These batteries do fit into my M12 drill, but have some play. The biggest disappointment is they die very fast. Nowhere near a true 3.0Ah Milwaukee brand battery. You get what you pay for. If i were to get new ones sent to me to replace to ones i have, i'd try again but expect the same results. Either save your money and buy authentic Milwaukee batteries, or get these and expect to spend more time charging than using.
