I designed this device to time the operation of the 120V AC battery charger for my battery powered drill. I found out the hard way that the battery chargers for these batteries run HOT. If left plugged in all the time, they will burn out. These type chargers run $40.00 to $70.00. Yes, it is true that this charger will cost $30.00 to $40.00, But, it will not burn out. The timer is a spring wound timer. The timer is basically a switch that will stay on for the time set. This switch (timer) will carry an electrical load up to 1HP (745.6 Watts). I have never had a timer go bad, but if it did you can replace it for $20.00 or less. The battery charger for my 19V craftsman drill draws 65 watts.
If you send me your email address & you are a LJ & mention Timer I will email you, FREE, a PDF file that has easy to follow instructions to build this project.
NOTE: If you do not get your plans within one day, PLEASE send me another massage.

I use the same setup to run an IR heater element and another for my glue pot. 1 hour is plenty of time to heat either. If I forget to turn it off, no problem…

That is an ingenious idea to make battery charging safer. I have read quite a few articles about guys setting their houses on fire from battery chargers..especially these new Lithium Ion batteries. This is a great, mechanical, set it and forget it set up. Thanks for sharing.

That’s a great idea!. Not only does it make charging safer and extend the life of the charger, but it also saves energy.

Check the manual for your battery chargers .. some do this automatically. Although most do not.

Don,
This looks like a great idea, but I’m just a little confused. Why can’t I just plug my rechargeables into the timer I use on my lights to automatically turn my charger off?

The lamp timer may work fine, but be careful not to overload it

Nice Idea, but couldn’t you just plug you charger into an ordinary light timer and when you charge your battery set timer on for as long as you want it to charge?

I have often wondered why someone hasn’t made a device like this or built it into the charger. Leaving them on all the time is just part of the phantom power consumption that goes on in our homes. All those little transformers for cell phones, cameras, printers, calculators, etc. etc.
