Batteries and Connections
Batteries are the key to maximum performance from your LD600-12, if a
battery is too small or not fully charged it may result in de-rated
performance from your LD600-12.
Battery ratings
Batteries can be rated in one of two ways:
1. CCA = Cold Cranking Ability. This is the amount of power or current
that a battery can deliver for a short period, typically a few seconds. This
how a car battery would normally be rated.
2. Ah = Ampere Hours. This is the maximum amount of energy that can be
stored in a battery; this figure will generally be stated at a particular hour
rate. This is how a deep cycle or storage battery would normally be rated.
100Ah @100hr, this means that when this battery is discharged over
a period of 100 hours, the battery has a capacity of 100Ah. This in
theory means 1 Amp for 100 hours, although this would in practice
result in a totally discharged battery that may not then recover.
To achieve maximum performance from your LD600-12 you must have a
battery capable of delivering 150 Amps for a short period whilst
maintaining at least 10.5 volts. To increase the capacity of your battery you
may need to join more than one battery together.
 Where batteries are joined
in series, add the voltage of
each battery.
The capacity will equal the capacity of the smallest battery. 2 x 6
Volt 150 Ah batteries connected in series would have a total
capacity of 12 Volts – 150 Ah.
