I have it from an absolutely unimpeachable source, i.e. the latest
issue of "Handy", the magazine of the Handyman Club of America, that
you are all wrong.

In response to a reader letter querying "The three manufacturers [of
his cordless tools] all recommend completely discharging the batteries
before recharging them. Which is the right way?", the HCOA responded
to ignore the manufacturers' suggestions:

"It's quite possible that the practice of completely draining tool
batteries before charging originated from the manufacturers of
earlier-generation tools. Regardless, now we know better. Do not
completely drain your batteries by holding down the trigger. As soon
as you detect that the tool performance is diminished, it's time to
recharge."

Who is wondering whether HCOA has some interest in getting people to
buy more batteries and who suspects the competence of their "advise"
is on par with the competence of their subscription department who
keep on sending the magazine despite his not having paid for it. OK,
in a momentary lapse of judgment 5 years ago, I did join and have the
drill bit index to prove it.


Surprisingly this is exactly what my 18 volt XRP DeWalt drill manual
says.("As soon as you detect that the tool performance is diminished,
it's time to recharge.")

Who thinks HCOA may have read a DeWalt manual before responding.
However, they most assuredly borrowed it from someone else as they
would never have a DeWalt tool for testing by a "member" since it
costs more than a drill bit index.
