Operation

Silent Power has 4 precision voltage regulators, 
each of them supplying 2 outputs with noise-
free 9 Vdc. The regulators are rated for at least 
500 mA continuously and 750 mA peak current.
This means that combined, the two outputs of a 
regulator should not draw more than these 
values. In the image below you can see how 
pairs of outputs are grouped for each voltage 
regulator.

Recharging

When the charger is plugged in and connected 
to Silent Power’s charging port, a red LED on 
the charger indicates that the device is charging.

When charging is complete the LED will turn 
green, signaling you to unplug the charger. 
Silent Power can be used also while recharging,
although in this case the charging will take 
longer.

Increase Battery Lifetime

The capacity of rechargeable batteries 
decreases over time, an important factor being 
how they are used. Here are some things you 
can do to increase the useful life of Silent 
Power’s battery pack:

use and recharge Silent Power at least 

once a month;

try not to use Silent Power below 10% 

charge level;

when not in use for longer periods of time,

keep Silent Power in a cool place (15 - 20 °C);

keep Silent Power 50-60% charged (not 

full, not empty) when unused for extended 
periods of time.
