Upgraded 2Pack 8.0Ah Replacement for Milwaukee M12 Battery and Charger Kit 12V Lithium Batteries Compatible with 12 Volt 48-11-2420 48-11-2401 48-11-2402 48-11-2430 48-11-2440 Cordless Tools

I picked up this 2-pack of 6Ah batteries for my Milwaukee M12 tools, and they’ve been performing extremely well. The extra capacity is noticeable right away, my drill and impact driver run longer without needing a swap, which makes projects smoother when I’m working through multiple tasks in one session. Both batteries lock into the tools securely, with no looseness or wobble. The fit is identical to the originals, and the connection is clean. Charging them on my existing Milwaukee charger works without issue, and the charge time is reasonable considering the larger 8Ah capacity. What stands out most is the consistent power output. There’s no sudden drop-off as they drain, and my tools keep the same strength from the first minute to the last. For anyone using M12 tools regularly, having two high-capacity backups like these makes a big difference in workflow. If you need reliable replacements that deliver strong runtime and full compatibility, this 8 Ah set is a great value and genuinely useful for daily tool use.

These batteries are made with good quality. They match the Milwaukee tools. It last long time for one charge. It can also be charged quickly. It functions good. Worth it.

These replacement batteries run my tools smoothly and hold a strong charge. I love the LCD display that shows the remaining power, its so helpful on big projects! They fit perfectly in my compatible tools. Great performance and reliable runtime. A solid upgrade for any tool kit!

Plugged right in worked in the tools.

This 2-pack of Milwaukee-compatible M12 12V extended batteries is a solid alternative to the name-brand versions that cost two to three times more. I cannot truly verify the 8.0Ah claim, but based on real-world use, the runtime and power output land somewhere between the XC 3.0 (retail: $130 for 2pack) and XC 5.0 packs (retail: $130 EACH), which is impressive for the price. They deliver consistent power all the way until drained with no noticeable drop-off during use. Tools run strong and perform exactly as expected for everyday and jobsite tasks. The built-in LCD battery percentage display is a great upgrade over the original Milwaukee batteries and makes it much easier to manage charge levels at a glance. Fit and compatibility have been perfect with my M12 tools, and charging has been hassle-free. For anyone looking to expand their M12 battery lineup without spending a fortune, these are a great buy and an easy recommendation.

Great batteries, these were super helpful! They are a great replacement! They have a long battery life as well! They are compact and work well! Would recommend

The Milwaukee M12 8.0Ah battery is an absolute game changer. The power boost and incredible runtime are immediately noticeable, letting me power through demanding tools like the Fuel hammer drill and Hackzall without a single pause. It balances the compact M12 system with near cord-like endurance. This battery has completely eliminated my downtime and is worth every penny. A must have for any serious M12 user

Not 8AH not even close. Lasts not even 10 min on Milwaukee due gender running speed 2. I’d try a different china brand. Some are good not this one
