Milwaukee48-11-2450 12V Lithium-Ion High Output 5Ah Battery Pack (G0803029)

Just received my pair of these 5.0 HO M12 batteries yesterday (May 6th '25). Sold by JB tools (a company I am familiar with and have purchased directly from in the past as well as on Amz), but shipped by Amazon. JB was listing for a Lincoln less, but is perpetually OOS. This was still of a bit of a gamble, in my opinion, as I always suspect that when there are dozens of sellers in the Amz Marketplace that essentially Amz is pulling stock from the same old bins, regardless of who is the "seller" purportedly is, and that fake / counterfeit "returns" often replace the originals when returned.Came in original packaging (hard plastic shell with plastic "heat spot welds" holding it together, indicating made in China by Milwaukee). Packaging looked legit (no misprints, mis-spellings, etc). T10H torx security screws - check. Batteries themselves looked legit / not fake or counterfeit, with proper labeling and durable material. On the bottom, just above the stick-on label, was imprinted a manufacture date (X-mas '24, actually), as well as a serial number at the very end. The two batteries' serial numbers were 8 digits apart from each other (...598, ...606), so I am comfortable saying they came from the same run, on the same day, and likely came out of the same box. Charged up fully in about an hour to an hour and a half, so par expected charge time for their amperage for my charger (my 4AH M12's are a bit faster). I may eventually pull the covers off to verify the Samsung battery cells, but so far I'm ok concluding they're legit. If anything changes, I'll update later.

I didn't realize how much I was being held back by the standard M12 batteries that came with my powerdrill. I was using the same battery for all my M12 tools, and would often run out of power quickly, and would stall out due to lack of power when using things like a cut off tool. Once I bought this bad boy and popped it into my cut off tool, it was like a new tool altogether. It lasted forever, and never shut off once due to needing more power. I should have gotten this a long time ago!

I've been a loyal Milwaukee user for years, and this M12 REDLITHIUM HIGH OUTPUT XC5.0 battery pack has taken my tools to the next level. Right out of the box, I noticed the robust build quality—this thing is built to withstand the rigors of daily use.Performance: The 25% more power claim isn't just marketing fluff; my tools run noticeably stronger and more efficiently. Tasks that used to bog down my drill are now handled with ease. Plus, it runs cooler, which means I can push my tools harder without worrying about overheating.Runtime: With 25% more runtime compared to the XC4.0, I'm spending more time working and less time swapping batteries. This is a game-changer on larger projects where every minute counts.Durability: The resistant housing is a thoughtful touch, protecting the battery from oils, greases, and solvents. I've accidentally dropped it a couple of times, and it still works flawlessly.If you're serious about your tools and demand reliability, the M12 XC5.0 is worth every penny. It's compatible with over 125 M12 tools, making it a versatile addition to your kit.

The Milwaukee rechargeable battery was packaged as the original product and protecting the product, sent and received timely.
