HF Cordless Drill Batt recharging
As some of you may have found out the hard way, HF charging bases for
the cordless drills do not have charge sensing circuitry or timer. Leave it plugged in too long, and the battery gets fried. I use this: http://www.harborfreight.com/cpi/cta...emnumber=40148 chronically on sale for 3-4 bucks at the stores. You set up the base/timer, Plug it in, Set it, And...Forget it! No more overcharged batteries.

Yes and note that most household timers offered in the box stores don't
accept three-prong plugs but this one does.

ONe more question: Doesn't it immediately start discharging when the charger is turned off by the timer?!? --- Every moment is a golden one for him who has the vision to recognize it as such. -- Henry Miller |

I get around that by splitting a duplex receptacle - feed power to one receptacle - thru timer to short two wire (polarized) cord feeding the other receptacle into which the load is plugged. OTOH, Noma has a nice, digital unit, but I loses it's program if the power goes off. Gerry :-)} London, Canada |
