Laptop/ drill rechargable batterys.. methods for longer life?

That's impossible, by definition.

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.

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. barry

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.

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.

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.
