Overall pretty good. However, when drilling a fairly large hole in thicker material using the 1/2" hammer drill/driver, the batteries get pretty warm and seem to go into overheat protection kind of quick. They work great with the 1/4" bit driver.

Bought a 2 pack of these babies and they didn't disappoint. Was very happy with my purchase. They last longer than the generic ones and have been holding up well.

De muy buena calidad. La marca lo garantiza. La batería se carga rápido y la duración de la batería en trabajo continuo es muy buena

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.

Milwaukee batteries are hands-down the best I’ve used. They provide consistent, long-lasting power that keeps my tools running strong, even during heavy use. Whether I’m working on a big project or tackling smaller jobs, these batteries never let me down.I also appreciate how quickly they charge and how durable they are—I’ve dropped them a few times, and they still work perfectly. They’re a bit of an investment, but the performance and reliability make them well worth it. If you’re looking for top-notch batteries for your Milwaukee tools, these are the ones to get!

Comes in what looks like a factory sealed and OEM Milwaukee blister pack. So far the battery performs just like an original. Great buy.

Review: Milwaukee 48-11-2425 M12 REDLITHIUM HIGH Output CP 2.5Ah BatteryRating: ⭐⭐⭐⭐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 SatisfactionThe 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 TechnologyMilwaukee 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 RechargeA 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 VersatilityOne 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 ImprovementThe only drawback could be its weight, which, given the high output, is on the heavier side for some M12 tools.
