Milwaukee M18 Super Charger

[joe_pinehill1]

I have a Milwaukee M18 chainsaw with the 12 amp battery. Up to now the dual 12/18 charger that came with the first M18 tool I bought over 10 years has worked fine. The 12amp takes forever to charge with the old charger. Anyone have the new Super Charger and use the 12 amp battery?

I don't have the super but have a insane amount of both standard and rapid. How many batteries do you have. I have enough batteries to rotate around. I still charge on the standard and the only rapid I use, is the one in my carry bag if I am mobile. Maybe I'm old school but low and slow is what I still adhere for batteries (if possible.

If you can you should.

I'm not a battery guru, but there is only 1 rule that changes in my Wiki House of Batteries....for example, deep cycle AGM's do want a high amp charge during charging vs . low and slow.

I don't have any of the 12AH batteries, but I have a friend with the fast charger. We were using my M18 lights when one of my 4AH batteries ran down and he suggested I use his fast charger. 10 minutes later, and it was at 3 bars.

I've got the supercharger (as well as every other Milwaukee charger known to mankind) and it only works faster than the fast charger on 6.0, 8.0 and 12.0 batteries which use the bigger Li-Ion cells. For all other batteries it's the same time as the fast charger. Here's a table of the charging speeds of the three different chargers: https://www.protoolreviews.com/milwaukee-m18-super-charger/ And yes, it's that fast on the 12.0A-hr. Unique to Milwaukee's chargers the Supercharger has a fan to cool the battery during charging. None of their other chargers do.

Heat is not good with batteries....

Hence, the discussion or debate on slow vs. supercharge
No one in this thread has typed in -heat- so I suppose YMMV,

Where's the debate? I wouldn't suggest taking a freshly charged battery, rapidly discharging it and then immediately putting it on a charger, fast or slow.

I just use a 6 bank charger. Start with highest rated battery and make my way down until the highest rated is charged.

Not debate. Discussion I suppose for the OP. AKA, charging on standard charger in theory is more healthier for the longevity of the battery vs. the super.

Maybe, but remember that the discharge rate is way above the charge rate of the standard charger, and nobody's complaining about that.

 

[mobiledynamics]

Ha. U got a point. But discharge is outta one's control vs. the latter

I simply assume that Milwaukee knows what it is doing. If using the supercharger would kill their batteries, which are fully guaranteed for three years, so they have considerable skin in the game, I don't think they would have released it. They put the fan in there for a reason and it does seem to work as the 12A-hr come off of it fairly cool.
