Review: Amazing - 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.
Review: Powerful batteries - 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.
