Battery charger timer

Timer doesn't work as far as counting down, but it does allow me to turn charger on and off now. Better than 120 bucks to replace charger. Defective timer possibly??

Hey Gordon,
You don't have to live with that - if anything isn't working 100% properly, just let us know.
We'll ship out a new timer to you tomorrow.
Best regards,

Mechanical Timer

Fantastic device and perfect for my application. I need to put a timer on an inverter to charge power tool batteries in the truck. The timer saves my battery preventing me from accidentally leaving the inverter on all night.
