- Reviewed in the United States on March 22, 2025I recently purchased the Milwaukee 4.0 battery, and it has completely exceeded my expectations! The performance is outstanding—providing consistent, long-lasting power for all my tools. Whether I’m using my drill, saw, or impact driver, this battery delivers reliable performance without any slowdown. It charges quickly and lasts significantly longer than other batteries I’ve used in the past. Plus, the durability of the battery is impressive; it handles tough conditions and keeps going strong. I’ve had zero issues, and the LED indicator is a nice touch to show how much charge is left. If you’re looking for a high-quality, powerful, and durable battery for your Milwaukee tools, this is a must-have. Highly recommend!
- Reviewed in the United States on August 4, 2024Im Milwaukee fan. Battery came dead but i have several batteries that get used daily and last years.
- Reviewed in the United States on September 16, 2024Second time I've purchased these, I have no complaints. Last ones were two years ago, still going strong and I beat the hell out of them at work. Ordered 4.0 but received 5.0 and they were in the original sealed packaging.
- Reviewed in the United States on August 24, 2023Expensive. Don't know how long it will last. The battery it was replacing, failed entirely. I believe it shorted out
- Reviewed in the United States on December 12, 2023For the price, I will admit I was skeptical at first. But after receiving my battery, I can confirm that it is a genuine Milwaukee battery that came as it would have from the factory. It charges as it should, and lasts as expected on my M18 tools. The 4.0 amp hour battery is a good middle size for use with smaller impact wrenches or on your drill if you need longer life. Overall, don't hesitate. If ordering from Amazon, it is legitimate.
- Reviewed in the United States on November 8, 2024Very good
- Reviewed in the United States on August 2, 2024Go with Milwaukee can’t go wrong
- Reviewed in the United States on April 10, 2025Defective battery used for less than 10 minutes battery died started a return I was told I was going to get invoice haven’t seen it yet
