One critical quality factor I never see covered with cordless reviews is
how many discharge/recharge cycles the battery pack is good for. With
Li-ion packs selling for $100 and up this is not a trivial concern.
There are a number of variations on Li-ion technology and manufacturing
processes which have a big effect on expected battery pack like.

I would encourage you to develop a benchmark procedure for testing this
characteristic and to start adding it to your reports.

From the review, "since when did Makita switch their tool colors to
black and white?"

The black and white Makita line is their "compact" version.

In the case of the drill, the equivalent green/black version is the
BDF451. The differences are:


560 in/lbs of torque instead of 450
somewhat longer/heavier
comes with side handle
3 speeds instead of 2
3.0Ah batteries instead of 1.5
45-minute charger instead of 15

I wasn't trying to be a critic or a smart ass, just making a suggestion
for what would be a useful improvement. If it is beyond the means of a
one-man band, no problem.

I think you've confused Dean Bielanowski for Consumer Reports. He
does kind of look like the September 1973 issue, but they're two
distinct entities.

How exactly would you suggest he implement such battery testing? The
guy is a one-man band and it's not big budget testing.

Lion cells have a certain amount of charging lives. keeping them
topped off can give you longer life since your not doing a full
charge. overall life if you used them both the same amount they would
not last as long. I went with them as my tools would sometimes
discharge too much over time.
the weight savings is really nice too.

Typically these batteries in these usages go twice as far between chargings
and typically have an expected life that is double that if a NIMH battery.
As with any battery, your mileage may vary with the type usage you have.
