Battery Types
Automotive Starting Batteries
The lead-acid battery you are most familiar with is probably the starting 
battery in your vehicle. An automotive starting battery is designed to 
deliver a large amount of current for a short period of time (so it can start 
your engine). Only a small portion of the battery’s capacity is used when 
starting the engine, and the spent capacity is quickly recharged by the 
running engine.
The starting battery in your vehicle is not designed for repeated deep-
discharge cycles where the battery is almost completely discharged and 
then recharged. If a starting battery is used in this kind of deep discharge 
service, it will wear out very rapidly.
Deep-Cycle Batteries
Deep-cycle batteries are designed for deep discharge service where they 
will be repeatedly discharged and recharged. They are marketed for use in 
recreational vehicles, boats, and electric golf carts—so you may see them 
referred to as RV batteries, marine batteries, or golf cart batteries.
For most applications of the XS400, Xantrex recommends that you use 
one or more deep-cycle batteries that are separated from the vehicle’s 
starting battery by a battery isolator.
A battery isolator is a solid-state electronic circuit that allows equipment 
to be operated from an auxiliary battery without danger of discharging the 
vehicle’s starting battery. During vehicle operation, the battery isolator 
automatically directs the charge from the alternator to the battery 
requiring the charge.
Battery isolators are available at marine and RV dealers and most auto 
parts stores.
