Nonsense.

The fact that both companies sell items for more than what it costs
to make or obtain them (which all companies have to do to stay in
business) does not bestow any form of equivalence on their businesses.

Both sell **** for *way* more than it's worth.

I think Panasonic, National Semiconductor, etc, etc, etc, would object to
having their products so-described.

Is it nonsense? You can certainly "offer" to sell something for more
than it's worth. But things *are* worth what people will pay for them.
Digikey is a phenomenally successful distributor that has grown
exponentially over the last twenty five years. Millions of loyal, repeat
customers find their offerings worth the price. If not, they would have
gone out of business long ago.

Certainly stupidity has its price. You seem to be a prime example. I
hope your boss is smarter.

Isn't Ron Popiel is still in business?

Let 'em. If they choose to sell through a disty that provides zero
service at 2-10x the price, who am I to tell them otherwise. I don't
know why anyone would be stupid enough to buy other than onesies
though.

I have had little used 14.4 volt drills that after 2 or 3
years the battery packs become very degraded. I this case,
the drill sits unused for a long period of time, then recharged
before next use.

Laptops, same story. occasional use, sits for awhile then used again.

Batteries are usually rated for so many cycles of recharging.
So, should it be better to constantly recharge the units,
or only charge as needed?

The charge as needed method for units that sit for awhile does not
seem to work out very well. I have a number of drill power packs
that i need to find some of those tab ni-cads for. I think there
c size or such. Anybody with tips on that let me know..

Keeping them constantly plugged in seems to me would use up
there number of charge cycles and shorten life to.

so, whats the best way to get the most out of rechargeable battery
packs?

And how can hybrid cars get 10 years out of a battery pack
when i am lucky to get 2 or 3 out of most of the packs i have?
I do see online how some of the early gen Prius packs are failing
much to the owners displeasure.

after frying a couple of 14 and 18 volt batt packs for my drills i
discovered the supplied 2amp wall warts were over kill for unregulated
recharging of the batterie packs
instead i found a smaller 750ma wall wart to do the job.
now even after 2months of sitting on the shelf my new battery packs
still hold their charge.

for port dvd players etc that use a transformer wall wart for home
use replace it with a switch mode device (at the correct voltage) and
there will no longer be problems of overheating.
reason is the supplied cheap wall wart puts out way more than is
needed causing the players built in regulator to lower it to say
12volts.
heat is the byproduct.
hybrid cars have a sophisticated charger that prevents destruction
due to improper recharging.

It's plain stupid using unregulated chargers in this day and age as
electronics are cheap and overcharging kills batteries in short order.

There are plenty of sophisticated charging ICs etc available to DIY one -
but a simple constant current charger set to 1/10th the capacity and an
overnight charge is the traditional way - and can be built for pennies.

Apparently it isn't selling as well as it was. Toyota is shutting
down its plants for 11 days over a two month period.

What a silly remark. Digi-Key is a major component supplier that's been
around about 20 years. They sell no consumer products.

They'll sell whatever manufacturers have to sell, at 2-10x the
going price. *Sounds a lot like Ronco to me, though their online
catalog is better.

Try 30 years. I have a 1978 Digikey catalog - about 50 pages.

They are older than that. they started with a kit of parts for a
electronic keyer for morse code, hence their name of Digi-key. It was
based on an article in a US amateur radio magazine, and they placed a
tiny ad for the kits.

I sold a TTY 33 to Ron Stordahl, founder, in about 1974 IIRC, for use at
Digi-Key.

The Prius maintains its batteries at between 50-80% of full charge.

And still doesn't achieve any more mpg than some non-hybrid cars. What a waste of time. I'm waiting for an ALL-electric car that can do over 70 miles range (that's my commute) and do at least 80mph. I think there is one just out, but it's £10 grand. I want a 2nd hand one.
