The Milwaukee M18 battery line is a renowned series of lithium-ion batteries that power the M18 tools from Milwaukee Electric Tool Corporation. These batteries offer a good mix of power, performance and longevity, which make them a fantastic choice for both professional and DIY users. In 2023, several M18 batteries stand out among the rest. In this review, we'll be looking at the top three M18 batteries of 2023.
Understanding Milwaukee M18 Batteries
The M18 series is Milwaukee's most powerful tool battery lineup. It is part of their M18 System of cordless power tools, which boasts over 200 products. The M18 batteries are designed to provide superior power, runtime, and durability. They are compatible with all M18 tools, making them a versatile choice for tradesmen, DIY enthusiasts, and homeowners.
Battery Technology & Power
Milwaukee M18 batteries use Lithium-Ion technology. Lithium-Ion batteries provide consistent power throughout their charge and do not suffer from the 'memory effect' that can decrease the effective capacity of rechargeable batteries over time. The M18 batteries come in various capacities, measured in Ampere hours (Ah). The higher the Ah, the more power the battery can store, thus providing longer tool runtime.
Milwaukee has integrated their proprietary REDLITHIUM Battery technology into their M18 batteries. REDLITHIUM batteries are engineered to deliver more work per charge and more work over their lifetime than any battery on the market. This technology combines with Milwaukee's REDLINK Intelligence (a system that communicates between the battery, charger, and tool for optimum performance) to provide superior power, runtime, and battery life.
Choosing the Right M18 Battery
Here's what to consider when buying an M18 battery:
- Battery Capacity: Milwaukee M18 batteries come in several capacities, notably 2.0Ah, 5.0Ah, and 9.0Ah. The 2.0Ah is a compact battery for lighter work and smaller tools, while the 5.0Ah is a decent all-rounder. The 9.0Ah is a high-capacity battery designed for heavy-duty work and tools requiring a lot of power.
- Battery Type: There are two main types of M18 batteries: Standard and High Output (HO). The M18 HO batteries use 21700 lithium cells instead of the 18650 cells found in standard batteries. This results in increased power output and longer runtime, making them a better choice for high-demand tools like circular saws, grinders, and blowers.
- Tools You're Using: Consider the tools you'll be using with the battery. If you're using high-demand tools, you might need an M18 HO battery. On the other hand, for lighter tools, a standard M18 battery might be enough.
- Number of Batteries: If you frequently use multiple tools simultaneously, having more than one battery can be beneficial. Many M18 batteries are sold in packs of two or more, and it's worth considering these if you're expanding your collection of M18 tools.
M18 Battery Maintenance
Proper maintenance can extend the life of your M18 battery. Here are some tips:
- Charge your batteries before they're completely drained.
- Store batteries in a cool, dry place.
- Avoid leaving batteries in the charger for an extended period after they're fully charged.
- Clean the battery contacts regularly to ensure a good connection with the tool.
