  3.6 Terminal Protection
Corrosion can build up on terminals if they are not kept clean and dry. To prevent corrosion, after 
tightening the fasteners, apply a thin coat of terminal protector spray that can be purchased through 
your local battery dealer.
3.7 Connecting Batteries to Increase System Power
You can increase capacity and voltage, or both, by conguring your batteries as follows:
Series Connect Parallel Connect Series/Parallel Connect
Note: maximum of three parallel strings
To increase voltage, connect batteries in 
series. This will not increase the system 
capacity.
To increase capacity, connect batteries 
in parallel. This will not increase the 
system voltage.
To increase both voltage and capacity, 
connect additional batteries in series 
and parallel.
EXAMPLE
Two T-105, 6V Batteries rated at 225AH 
Connected in Series
Two T-105, 6V Batteries rated at 225AH 
Connected in Parallel
Four T-105, 6V Batteries rated at 225A 
Connected in Series/Parallel
Voltage 6V + 6V = 12V System 
Capacity = 225AH
Voltage 6V System 
Capacity = 225AH + 225AH = 450AH
Voltage 6V + 6V = 12V System 
Capacity = 225AH + 225AH = 450AH
