Craftsman V20* 4.0Ah Lithium Ion Battery

Craftsman has long been a trusted name in the realm of power tools and accessories, and their V20* 4.0Ah Lithium Ion Battery, model CMCB204, aims to uphold that reputation. I've had the opportunity to integrate this battery into my routine, and my experiences with it have been a mixed bag. Below, I offer an in-depth exploration of its performance, features, and overall value.

First Impressions and Build Quality

Right out of the box, the V20 4.0Ah battery feels robust and well-made. The casing is solid, and it exudes a certain ruggedness that suggests it can handle the bumps and scrapes of a typical job site. Weighing in at 1.4 pounds, it's not overly cumbersome, yet it feels substantial enough to signal its capacity.

The 3-LED state of charge indicator is a thoughtful touch, providing a quick visual check of the battery's remaining power. This feature is handy when you're in the middle of a project and need to know if you have enough juice to complete the task at hand. The battery also boasts high-performance cells designed to offer improved power and a longer cycle life, which is a significant selling point for anyone who relies heavily on cordless tools.

Performance in Real-World Use

I primarily used the V20 4.0Ah battery with a Craftsman brushless drill and a 1/4-inch impact driver. Upon fully charging the battery, I was eager to see how it would perform under different conditions.

In terms of power, the battery did not disappoint. It provided ample energy for drilling through tough materials, and the impact driver had no trouble driving long screws into thick wood. The high-capacity cells genuinely seem to make a difference in performance, delivering consistent power without noticeable dips.

However, it's not all smooth sailing. While the battery performs exceptionally well in short bursts, its endurance leaves something to be desired. During extended use, especially with high-drain tools like a grinder or a heavy-duty drill, the battery's charge seemed to deplete faster than I expected. For instance, using the battery with a grinder to cut through 14-gauge steel, I found myself needing to swap out or recharge the battery more frequently than I would have liked.

Charging and Battery Life

The charging process itself is relatively straightforward. Using the Craftsman V20 charger, the battery typically takes around 45 minutes to an hour to reach a full charge. This isn't particularly fast, but it's reasonable given the battery's capacity.

One issue that did arise was the battery's lifespan between charges. While it can hold a charge for lighter tasks, more demanding applications will see the battery life diminish quickly. This becomes problematic if you're working on a larger project and don't have multiple batteries on hand. The battery does exhibit a low self-discharge rate and no memory effect, which means it retains its charge well when not in use. However, for heavy-duty tasks, you might find yourself swapping batteries more often than you'd prefer.

Compatibility and Versatility

The V20 4.0Ah battery is compatible with the entire Craftsman V20 cordless tool lineup, which is a significant advantage. Whether you're using a drill, saw, blower, or weed eater, this battery integrates seamlessly across various tools. This universality adds a level of convenience, eliminating the need to juggle multiple battery types for different tools.

Durability and Reliability

Durability is an area where this battery shows mixed results. On one hand, the robust build quality and high-performance cells suggest a long-lasting product. On the other hand, there have been instances where the battery's performance declined prematurely. During my use, I did not experience any sudden failures, but it's worth noting that some users have reported issues with their batteries not holding a charge after only a few months of use.

Overall Value

Considering its price point, the V20 4.0Ah battery offers a decent balance of performance and capacity. It's particularly useful for those who have already invested in the Craftsman V20 ecosystem, as the compatibility across tools adds significant value. However, if you're expecting this battery to power through multiple heavy-duty tasks on a single charge, you might find it falling short.

Final Thoughts and Recommendations

In summary, the Craftsman V20 4.0Ah Lithium Ion Battery provides solid performance with some limitations. Its high-capacity cells deliver consistent power, making it suitable for a range of applications. The inclusion of a 3-LED state of charge indicator is a practical feature, and the battery's compatibility with the V20 lineup adds versatility.

However, the battery's endurance, especially under heavy use, could be improved. Frequent recharging and the need for multiple batteries might be necessary for larger or more demanding projects.

Would I recommend the Craftsman V20 4.0Ah battery? Yes, but with reservations. If you're a DIY enthusiast or a homeowner with light to moderate usage, this battery will likely meet your needs and provide satisfactory performance. However, if you rely on your tools for professional, heavy-duty tasks, you might want to consider investing in additional batteries or looking into higher-capacity options to ensure your workflow remains uninterrupted.
