The second major component is the choice of
batteries.

The Battery
|
|
| The type of battery
is of importance when deciding on an isolator. |
|
|
| |
Car Batteries |
Ideal use - starting motors, light electrical accessories
use and light winch application. Its best feature is its price (fairly
cheap). |
| |
Truck Batteries |
Ideal use - heavy duty starting application, winching
work, light accessories work. Best feature:- tough reinforces plates,
high cold cranking amps (CCA), reliable starting and great for winching
work. |
 |
|
Deep Cycle |
Ideal use - fridge, CB, HF Radio, camping lights, inverters,
in fact any low amp drain over a long period of time. Best features:-
long life, and can be flattened many times without significant damage
to the plates |
| |
When choosing a battery style we must think
of a comparison as a truck versus sports car. They are both motor
vehicles but they are designed from the ground up for different purposes.
In a truck or car battery we have 12 - 17 plates per cell giving us
huge area contact with the acid thus giving an enormous capacity to
produce power (CCA) is a rush, but little staying power. |
| |
A deep cycle may have as little as 4 plates
per cell however they are much thicker and denser, therefore the acid
penetrates more slowly giving a lower CCA but much better staying
power. |
