Review: Tengo un taladro Milwaukee m12 creo 1era generación; pero lo he cuidado bastante y no lo uso con frecuencia; ya tiene por lo menos 7 años y las baterías originales ya no retienen tanta carga por eso decidí comprar esta batería y me sorprendió que el taladro se siente más potente (es el mismo voltaje; pero sentí que giraba el taladro con más fuerza y más rápido; quizás sea una apreciación subjetiva; pero así lo percibí). La Batería llegó perfectamente empacada (nueva) y embalada. Concluyendo: recomiendo bastante los taladros milwaukee M12 si eres de los que hacemos bricolaje ocasionalmente son herramientas y baterías de gran calidad y con gran poder y desempeño.
Review: Review: Milwaukee 48-11-2425 M12 REDLITHIUM HIGH Output CP 2.5Ah Battery Rating: ⭐⭐⭐⭐½ (4.5/5) In a world increasingly dependent on cordless power tools for both professional and personal use, having a reliable, long-lasting battery is not just a luxury, it's a necessity. The Milwaukee 48-11-2425 M12 REDLITHIUM HIGH Output CP 2.5Ah Battery is a powerhouse in a compact form, offering a blend of durability, power, and innovation. High-Output, High Satisfaction The first thing to notice is the 2.5Ah capacity. It's not just a number on a package; it's an insurance of extended use. Milwaukee's REDLITHIUM technology ensures a longer run-time and overall battery life. Whether you're a professional on a job site or a DIYer at home, this high-output battery keeps you going when you need it the most. Toughness Meets Technology Milwaukee doesn't just stop at high-capacity; they've built this battery to withstand tough conditions. The robust construction ensures that it survives the inevitable bumps and drops of active use. Moreover, it features advanced overload protection, which safeguards both the battery and the tool it's powering. Rapid Recharge A powerful battery is only as good as its charging time, and here too, Milwaukee delivers. The rapid recharge rate means minimal downtime, so you can get back to work faster. Pair it with a quality Milwaukee charger, and you're looking at a system designed for efficiency. Compatibility and Versatility One of the most appealing aspects of this battery is its broad compatibility with Milwaukee’s M12 lineup. This means you can easily swap it between different tools, increasing the battery's utility and decreasing the need to carry multiple battery types. Just a Smidgen of Improvement The only drawback could be its weight, which, given the high output, is on the heavier side for some M12 tools. While this isn’t a major issue for many applications, those using it for extended periods in a hand-held tool might feel the difference. The Verdict The Milwaukee 48-11-2425 M12 REDLITHIUM HIGH Output CP 2.5Ah Battery is a robust, reliable, and highly efficient power source. It offers substantial improvements in both run-time and durability, making it a crucial component for anyone serious about their tools. So, if you're looking to upgrade or replace your current battery, this is a top-tier option worth every penny. Power your projects the right way with Milwaukee’s proven quality.

## Questions & Answers

**Q: Are these guaranteed authentic and what is the date code on them? Thanks**
A: If you buy these from The TOOL GUY they are the real deal, I can not give you the date code that is part of the serial number without opening the package and if I open the package and ship it to you opened you will think it's used or counterfeit lol

**Q: Can the charger for the 2.0 batteries work with the 2.5Amp batteries?**
A: Yes. I have 3 of these batteries and regularly use them on the old charger

**Q: I can use for m12 the heated gear?**
A: Heck yes! If it's an M12 battery, it fits all the M12 tools and heated gear! The HO batteries seem to last longer in the jacket and run cooler too. I don't know if it's just a mental thing but the med setting (which is where I run my jacket at) seems to be a little warmer with the HO batteries than with the CP or XC batteries. The high setting now almost seems too warm with an HO battery!

**Q: Has anyone bought one and opened it up to see if this listing is selling authentic batteries? these retail for $80 so i have major doubts.**
A: What we sell is Milwaukee made brand. This is a limited time promotional price that ends 5-12-2023
