6 Battery Selection and
Charging
6.1 Battery Sizing (General Information)
The battery or batteries selected should be determined based on the
applications you plan on running with the PORTAWATTZ 400.
These are two common battery types:
Automotive Lead Acid – These batteries are designed to deliver a
large amount of current for a short period of time and are typically
located in the engine compartment of a car or truck. This design
works well for starting the engine of a vehicle.
Only a small portion of the battery’s capacity is used for starting the
engine, and once started, the vehicle’s alternator quickly recharges
the battery. Unlike deep cycle type batteries, automotive lead acid
batteries are not designed for repeated cycles of full discharge and
recharge. For this reason, we recommend using this type of battery
when most of your applications are 300 Watts or less and operating
times are relatively short (1-2 hours), or if your vehicle’s engine is
kept running when the inverter is used.
Deep Cycle Lead Acid – These batteries are designed for repeated
cycles of full discharge and recharge and are often used in RVs,
boats, and golf carts. Select this type of battery when most of your
applications require higher power (more than 300 Watts), your use of
the inverter is frequent, or when you run applications for extended
periods of time (more than 2 hours).
When a deep cycle battery is used in a vehicle, we recommend
installing a battery isolator to prevent the auxiliary deep cycle battery
from discharging the vehicle’s starting battery. The isolator
automatically directs the current from the vehicle’s alternator to the
battery requiring a charge. Isolators can usually be purchased at auto
parts, marine, or RV stores/dealerships.
CAUTION! Connect PORTAWATTZ 400 only to batteries with
a 12-Volt nominal output. A battery with 6-Volt nominal output
will not supply enough voltage and a battery with 24-Volt
nominal output will damage the inverter.
Just as important as the type of battery selected is its size or capacity.
A large battery will extend running time and ensure that your
PORTAWATTZ 400 delivers its full rated surge. For most
applications, batteries from 50Ah (120 reserve minutes) to 400Ah
(1800 reserve minutes) will be sufficient, but depending on your
