Milwaukee M18 High Demand 9.0 AH Battery Additional Warnings

Milwaukee sent out a press release detailing specific warnings in regard to the Milwaukee M18 High Demand 9.0 AH battery. Before we dive too far into this, it’s important to note a couple of things. First, this isn’t a recall and there’s nothing wrong with the packs. In fact, there’s not a situation or incident to report on at all. Milwaukee is just taking a proactive approach to educating their user base.

Second, we expect just about everyone in the industry to address this at some point as batteries grow more powerful and have greater capacity. And finally, what Milwaukee is asking users to consider is not unique to only the Milwaukee M18 High Demand 9.0 Battery, nor are they different than the warnings you’ll find on every lithium-ion battery pack. They’re simply being more specific.


Milwaukee M18 High Demand 9.0 AH Battery Warnings

Essentially, the press release is just a reminder that highly conductive and corrosive liquids can have disastrous consequences on your battery. Liquids like bleach, salt water, and a plethora of other chemicals can create a connection between cells and cause a battery failure. In its most spectacular form, that can cause the battery to smoke or catch fire.

With hoverboards and smartphones making the news for their actual battery failures, it’s a good reminder of how reactive these packs can be – if they’re mishandled or poorly constructed. There’s nothing wrong with the construction of Milwaukee’s packs, but there can be serious consequences if you’re not conscientious of your usage.

Do Not Try This at Home

Here at Pro Tool Reviews, we love to test tools and sometimes we push them to the limits. But we’re Pros and we take a ton of safety precautions behind the scenes that don’t make it into the reviews. Even with our desire to bring you the latest information to keep you educated, we’re not touching this one with a 10-foot pole, fire suit, or blast doors. It’s just not worth it.

What’s more is that the failure of a lithium-ion battery isn’t necessarily instantaneous. It can happen hours or even days later. And if you’re like most of our Pros, you don’t have eyes on where your battery storage 24/7 to do anything if a fire does start.

So if you’re really curious, just do a YouTube search. But please, don’t try this at home.


Why is the Warning Attached to the Milwaukee M18 High Demand 9.0 AH Battery?

Milwaukee M18 Fuel String Trimmer

When we spoke to the gurus at Milwaukee, they used a rather simple, but intelligent word picture to help us understand why this is just now becoming an education focus for them.

Take two ladders – one with a 3-foot working height and the other with a 10-foot working height. Which will do more damage if you fall off of it?

The taller ladder, of course. It’s a similar idea with the Milwaukee M18 High Demand 9.0 AH Battery. The increase in overall energy storage is much greater and the failure potentially more dangerous. So like when you’re working at higher elevations, more precaution is in order.

But like I said, the warnings are the same for all lithium-ion batteries, there’s just a greater point of emphasis to educate end users as they get more powerful. It’s always a good idea to avoid getting any liquid inside your battery packs, but some liquids are worse than others.

Please be careful people. These batteries can just explode and catch fire with normal use. I am not sure how often it happens as Milwaukee will not make the info readily available. Scary stuff and when it does happen they are NOT helpful

Just a Side Note here. Lithium Batteries have been used in Motorcycles for several years. For good reasons. Take my HD Street 750 for example. Stock Battery(AGM) is 225cca. Weighs around 10 Lbs. I replaced with a Direct Fit. No Adapters or shims needed Lithium replacement. Makes 330cca. And only weighs 2-3 Lbs. Have heard stories on occasion about them catching fire. This is not my first one. Actually this is the 2nd bike I did this too. Use the Proper Charger, Never had a problem.

Pretty sure I can handle not dropping my 9.0 in the ocean or a pool of bleach.

This post is extremely misleading to what the specific warnings explain.
