[AT] Lawn mower carburetors are a piece of cake..... Wrong--NOW Battery Power

[Brad Loomis]

I believe most  if not all newer LI tool battery chargers limit the amount
of 'charging' they do to prevent over charging, battery degradation, etc.
People get PO'ed when they have to drop a hun and a half on a battery.
Granted they still go bad, but not like the Mikcheepas of old. I have a
fair amount of Milwaukee 28V tools that I still use today. I've had to
replace two batteries and at pushing $200 a pop I may not get anymore. I'm
too old to invest in an entire stable of new 12, 18, or whatever volt
tools. Mine serve their purpose. However if I were 20 years younger then I
would definitely invest in new, red tools. We have a few at work that are
really nice. That 18V transfer pump is terrific. These days if I need
something I'm probably going to get pneumatic or corded. They are way less
money as a general rule.
