I did this with the xc5.0 battery as the primary item a few days ago, though for $110 and change. finally have a big battery for my 2.5gal vac!
fyi, there are (or were) a lot of options for the combo item using the xc5 as primary, but there weren't with the ho12

The 12.0s seem to die so fast compared to the others…
I've had 2, both hardly last in the tools. I've tried to disassemble and repair the cells, and that didn't work either.

I think the strategy of more smaller batteries is better.
I have to switch it out more, but then the other is charging, and I'm not out so much when one of these monster batteries inevitably dies.

Do not drain it completely. It will not take a charge thereafter. Watched a few YouTube videos about the 12ah and several suggested that was the cause of premature failure. I have had mine for over a year and no issues using this strategy.

Shoot... I'm not supposed to be spending any more money on tools for awhile but this would be nice for my vacuum...

Isn't this the battery that dies all the time? is it really a deal with it's known poor reliability?

I agree 100% I use my 4.0 high output batteries as my daily tools and leave the 12.os for my stationery saws. I only commented because millwaukee cordless has come along way from the beginning of my Red collection.

Milwaukee stick vacs are horrible. I'm guessing Gen 2 coming soon.

M18 Fuel Packout 2.5gal wet/dry vac is actually good and super handy. My wife uses it more than me around the house for quick messes.

1 year is nothing. I'm in the trades and use a lot of my dewalt batteries daily. Some are as old as 2017 and still charge to full bars. Thinking it's good because it's lasted 1 year is not impressive…unless you maybe used the same battery everyday in highdrain tools like a leaf blower all day - charging and discharging multiples times a day everyday…in that case maybe a year would be impressive relatively

Same issue here. I have 5 of those and 4 of them died quickly.

Regarding the dead battery issue, TTI batteries (Milwaukee/Ridgid) seem to not charge if the voltage gets too low (this is when you get flashing red and green on the charger). If you hook up the battery to a 9V battery for a few seconds (I use razor blades and alligator clips), the voltage will get high enough so the charger will allow it to charge again. I have used this trick literally a dozen times to revive dead Milwaukee batteries.

Btw I've never had a DeWalt battery die... Smilie
