Battery Reference
The stimulus isolator uses an onboard Lithium-Ion battery for general device
operation. These batteries charge in four hours. A 6-9 Volt battery charger with 500
mA of current capacity is included with the stimulator and can be connected via the
Charger connector on the stimulator's back panel. The charger tip is center negative.
If it is necessary to replace the charger, ensure that the power supply has the
correct polarity.
