Introduction
The Charge-O-Matic
TM
is a simple to use device that solves the age-old problem of powering and/or
charging devices that need to be periodically charged or powered for several hours, but then need to remain
unpowered for many days to avoid overcharging and damaging batteries. Example use cases include electric
start backup generator batteries, electronic devices that are infrequently used, power tools and more.
There have been many commercially available timers on the market, but typically these devices are limited
to an powered-on duration of only 24 hours, at an interval period of 7 days. The Charge-O-Matic
TM
allows
powered-on durations of much longer, up to 99 hours–at intervals of anywhere between 1 and 99 days. For
example: Generator producer Generac explains on their website, “The customer should charge the battery at
least once a month for 24-48 hours in preparation for usage... The charger should be connected for no longer
than 48 hours.” Most customers do not remember to charge and unplug their generator batteries monthly.
Inevitably, they leave the batteries connected to the charger indenitely, damaging the battery, and leaving
them with a dead battery when it is time to use the generator. With the generator’s charging cord plugged
into the Charge-O-Matic
TM
, the customer could set the Powered On Duration period to 48 hours and the
Days Between On Cycle to 30 days. The timer would then power-on for 48 hours and then power itself o for
30 days, at which point it would again power-on for 48 hours, and then again power o for 30 days and so
on, indenitely. No more remembering to plug and unplug devices. While this is one use-case, the Charge-
O-Matic
TM
can be used for any device that would benet from power cycles at intervals.
Setup + Operation
1. Plug timer into grounded electrical outlet in a dry location.
2. Set number of hours to Power On by pressing the left knob labeled “Power On Duration” (num-
bers on both displays will ash to indicate the values can be changed). Rotate left knob until left
display shows desired on time (choose any value between 1 and 99 hours). NOTE: After 5 sec-
onds, the timer will automatically end programming mode. Simply press the knob again if you
need more time to adjust the value.
