Milwaukee Battery Guide Part 3: Battery Care & Replacement

Replacing Older Milwaukee Batteries

Eventually, every rechargeable battery reaches the point where it needs to be replaced.

Sometimes that’s because it has reached the end of its service life. Sometimes it’s because Milwaukee has introduced newer battery technology and discontinued an older model.

The good news is that replacing an older Milwaukee battery is usually straightforward.

In many cases, you don’t need to find the exact same battery you bought years ago. A newer model may provide longer runtime, better performance, or faster charging while remaining fully compatible with your tools.

Should You Buy the Same Battery Again?

Sometimes.

If you’ve been happy with the way your battery performed, buying the current equivalent is often the right choice.

If your work has changed over the years, this can also be a good opportunity to move to a different battery.

For example, someone who has added grinders, rotary hammers, outdoor power equipment, or high-torque impact wrenches to their cordless collection may benefit from moving to HIGH OUTPUT or FORGE batteries.

When someone asks for a replacement battery, one of the first questions we ask is, “What tools are you using now?” The answer is often different than it was five or ten years ago, and that can change the recommendation.

Getting the Most from Your Milwaukee Batteries

A quality Milwaukee battery is an investment. While no rechargeable battery lasts forever, a few simple habits can help you get the most from the batteries you own.

Bring Your Batteries Inside During Winter

Milwaukee batteries are designed to work in cold weather, but contractors who bring their batteries inside on cold winter nights may notice longer battery life over the years.

If a battery has been sitting in a freezing truck overnight, let it warm up before placing it on the charger.

Winter is part of the job in Canada. Bringing your batteries inside at night is a simple habit that may help protect your investment over the long term.

Rotate the Batteries You Own

If you own more than one battery, use all of them.

It’s tempting to keep one battery on the shelf as a spare while using the same battery every day. We’ve found it’s usually better to rotate through your batteries so they all see regular use.

From the Counter

If you’ve invested in a second battery, let it earn its keep. Rotating your batteries helps spread the charge cycles across your battery collection instead of putting them all on one battery.

Keep the Battery Contacts Clean

If a battery doesn’t seem to be charging properly, take a quick look at both the battery and charger contacts before assuming the battery has failed.

Dust, dirt, and jobsite debris can sometimes interfere with a good electrical connection.

A quick inspection only takes a few seconds and may save unnecessary troubleshooting.

Don’t Ignore a Damaged Battery

If a battery has been dropped hard, has a cracked housing, shows signs of swelling, or behaves unusually while charging, stop using it until you’ve determined the cause.

Replacing a damaged battery is less expensive than also damaging a tool.

From the Counter

Most Milwaukee batteries are built to handle tough jobsites, but if a battery has obvious physical damage, it’s worth having it checked before putting it back into service.

Milwaukee Battery Warranty

A Milwaukee battery is an investment, so it’s understandable to wonder what happens if something goes wrong.

Milwaukee batteries are backed by a manufacturer’s warranty, although the warranty period varies depending on the battery model.

If you think your battery may have failed under warranty, don’t throw it away or assume you’ll have to deal with Milwaukee directly. Bring it in and we’ll help you determine the next step.

From the Counter

If you purchased your Milwaukee battery from Contractor Cave, there’s no need to find your receipt. We keep your purchase history on file and can look it up for you.

If you purchased your battery from another Milwaukee dealer, simply bring your original proof of purchase and we’ll still be happy to help with your warranty claim.

Not sure whether your battery is covered?

Bring it in.

We’d much rather take a look than have you replace a battery that may still qualify for warranty.
