4.3 ENHANCING THE POWER
CAPABILITY OF PRIMARY BATTERIES
When electronic equipment is powered by a primary (non
rechargeable) battery, one of the limitations is the power
capability of the battery.
In order to increase the available current from the battery,
while maintaining a constant voltage drop across the battery
terminals, the designer must connect additional cells in
parallel leading to increased size and cost of both the
battery and the finished product.
When high power is only required for short periods more
sophisticated approaches can be considered. The tradition-
al approach involves using a high power rechargeable
battery, charged by a low power primary cell.
A far superior solution, however, is the use of a BestCap
Supercapacitor, which is a device specifically designed to
deliver high power.

• Substantially lower voltage drop for pulse durations of up
• Substantially lower voltage drop at cold temperatures
• Discharge current limited only by the ESR of the capacitor

ed in parallel to a Lithium Tionil Chloride, to the same
primary battery connected to a BestCap
