Milwaukee Batteries

Milwaukee Batteries

The best way to power the cordless tools that Milwaukee manufactures is with Milwaukee battery chargers. The chargers are available in many sizes because most of them are not universal and only charge certain size batteries.

For instance, 14-volt batteries only use 14V chargers, and the M12 tool line only uses 12 Volt battery chargers. However, they also make at least one battery charger that can charge two types of batteries at once.

Types of Milwaukee Battery Chargers

Milwaukee makes a rapid charger, the Milwaukee 48-59-1807 M18 & M12 Rapid Charge Station, that can charge both 18V and 12V batteries at once. However, it is the exception. Also, not every battery charger needs an outlet to recharge batteries.

The Milwaukee 48-59-1201 M12 Charger and Portable Power Source can plug into a USB outlet, including one that’s in a car, to recharge the batteries. These examples are just two of the chargers and power sources that the company makes for providing their tools with long-lasting power.

Why Buy Milwaukee Battery Chargers?

By purchasing a battery charger from Milwaukee, you will feel good knowing that the battery and charger match. The Redlithium batteries are specially designed to provide up to 50 percent more power than other lithium-ion batteries. So only a Milwaukee charger can keep up with their batteries’ power demands.

Don’t risk trying to charge Milwaukee batteries with an off-brand charger. Each charger from Milwaukee has REDLINK technology to properly manage the temperature of the batteries and charger, plus the voltage to make charging them safe.

If you attempt to charge a Milwaukee battery with another company’s charger, it can sustain damage, and its longevity can be affected. Each Milwaukee charger comes with a three-year manufacturer warranty, so if something goes wrong with it, contact the customer service at Milwaukee.

Milwaukee M18 Batteries & Charging Kits Tips

If you plan to use your tools over extended periods and want to reduce strain, you can opt for compact Milwaukee M18 cordless tool batteries, which weigh less than the standard version while still delivering exceptional power. For those times when you want to go longer without recharging, the XC line offers longer running times than other models. All Milwaukee M18 rechargeable batteries have REDLINK PLUS™ Intelligence, a system that regulates the rate at which they consume power and prevents overheating and overloading for safer work.

If you are just starting out, you should get your batteries as part of a cordless combo kit, with a charger and one or two batteries. For those times when you have a full crew working, multi-charger stations can power up to four Milwaukee M18 batteries at a time so you and your team can swap between the charger and the tool to keep everything going with minimal downtime. Opt for a fast charger model when you’re using high-powered tools that go through a charge more quickly.

Their lithium-ion design prevents these Milwaukee M18 cordless tool batteries from developing a memory, so their maximum charge remains consistent throughout their operational life. FUEL™ gauges on the side give you a clear indication of how much power you have remaining. Their easy-to-lock and release mechanisms make changes fast and simple.
