To fix this problem, I made a timed duplex power outlet. I plug the timed outlet into a 120v outlet. Then, plug the battery charger into the duplex outlet attached to the timer. Finally, I set the timer to 20 minutes and walk away.
The parts list to make this is simple:
- One (1) double gang electrical box.
- One (1) GE 15305 In Wall Spring Wound 60 Minute Countdown Timer
- One (1) duplex outlet
- One (1) old power cable from a computer
- Extra electrical wires (black / white / green)
Making this is also simple.
