Quick Milwaukee Fuel Battery Life Question

[Sigma.40]

I'm a professional auto tech working at a shop that specializes in engines and I'm very interested in switching from air to electric tools. I'm particularly interested in Milwakee Fuel

I'm looking at the M18 1/2" (1400lb ft) and M18 3/8" impact. Also the M12 3/8" and 1/4" ratchets. The impacts would each come with a 5 AH battery and the ratchets would each come with a 2AH battery. Obviously, it depends on how much I use them but how long do the batteries last? Could these batteries last a full 8 hour shift? I can't find any info on battery life anywhere.

Unfortunately, the tools with 1 battery each will pretty much max out what I have to spend so buying more or bigger batteries won't really be an option for awhile. I'd really appreciate any info on these as I'm looking at buying them very soon. Thank you!

Yes. I would say they would last 8 hours no problem, the only exception being if you were hammering on a stuck fastener for 30 minutes several times a day. The impacts and ratchets are some of the most efficient tools. I've heard of guys going 3 days or more on a battery. When it comes to the impact and ratchets, 2 batteries each is more than sufficient.

I usually charge my M18 3/8 Impact ever other day while working 12 hour shifts assembling Garbage trucks

They are intermittent use type tools. Depending on what you're doing, yes they can last all day, or worst case you swap another battery in. I use the utility version of the high torque, and two batteries will get me through a day. All of the power tools I use at work are cordless. Including rotary hammers.

They are not "drill holes all day long" type tools. I've done that before. Cordless doesn't make sense for that "I'm literally drilling as many holes as I can" type work. But use for few minutes, put down, pick up again in 30 minutes, repeat - type work, yes cordless is fine. MANY pro mechanics rely on cordless tools now. Your experience should be no different than theirs. Nonstop use of a fuel grinder with a 9.0 battery I've gotten like 45 minutes out of a battery under a load.

Ok, thank you all very much. I guess I will be buying them!

I have worked professionally in automotive with milwaukee. While they do work and you probably won't care, I'd recommend ingersoll. Much better tools and the newest 3/8 impact is amazing.

IR cordless stuff is pretty awesome, but they're even MORE expensive than Milwaukee(which is already pricey). Also they have what, 10 tools? To milwaukee's 150? Not dawging IR, they're great, just giving some pros and cons

My 1/2" air impact is IR and it's great, but I like the fact that I can roll in anywhere and buy Milwaukee batteries and tools. Even my Snap On guy sells Milwaukee. I haven't ever seen IR electric stuff
