Before getting started
Before getting started:
• Make sure you know your system voltage, battery compartment size (length, width and height) and your energy needs.
• Determine whether you want to use a deep-cycle flooded, AGM or Gel battery.

Step 1: Determine your battery voltage and how many to use
1-1 Based on your system voltage, you must first decide which battery is needed and how many to use in order to meet your requirements. For example, you may connect a series of eight 6V batteries, six 8V batteries or four 12V batteries for a 48-volt system. The size of your battery compartment, your performance requirements and costs may limit your options.

1-2 Make sure there is enough space between batteries to allow for minor battery expansion that occurs during use and to allow proper airflow to keep battery temperature down in hot environments.

TIP: Connecting batteries in series does not increase the capacity of the batteries; it simply increases the overall voltage to meet your system requirements. Once your voltage requirements are met, if space allows you can double the batteries in a parallel connection—thereby doubling your battery capacity. See diagrams below.

   
Series Connect
To increase voltage, connect batteries in series. This will not increase the system capacity.

Example :
Two T-105, 6V Batteries rated at 225AH Connected in Series

System Voltage: 6V + 6V = 12V
System Capacity = 225AH


To increase voltage,
connect batteries in series.
   
Parallel Connect
To increase capacity, connect batteries in parallel. This will not increase the system voltage.

Example :
Two T-105, 6V Batteries rated at 225AH Connected in Parallel

System Voltage: 6V
System Capacity = 225AH + 225AH = 450AH


To increase amp-hour capacity,
connect batteries in parallel.
   
Series/Parallel Connect

To increase both voltage and capacity, connect additional batteries in series and parallel.

Example :
Four T-105, 6V Batteries rated at 225AH Connected in Series/Parallel

System Voltage: 6V + 6V = 12V
System Capacity = 225AH + 225AH = 450AH


To increase both voltage and
amp-hour capacity, connect
batteries in series/parallel.

Step 2: Choose your best battery model
2-1 When choosing your battery model, first consider your battery compartment space as this may limit your options. Within your size restrictions you may have several battery options to choose from. For example, you can use a T-605, T-105 or T-125 in the same space, as they are the exact same physical size. The difference between these batteries is the amount of energy they have to offer.

2-2 Next consider your energy needs. If replacing an existing battery, use it as a reference point. If your old battery provided enough energy, it can be replaced with a similar capacity battery. If you need more energy you can size up, or if you need less energy you can size down.

TIP: If you do not know what battery to use, contact your equipment manufacturer for their recommended battery specification. Trojan Battery also offers outstanding technical support provided by full-time applications engineers to help you select your ideal batteries.

Step 3: Select your best terminal
3-1 Finally determine which terminal option best meets your needs based on the type of cable connections you plan to use. Look for the terminal(s) available for the battery you have selected. (Please see the back page of this guide for available terminals to make your selection.)

TIP: Make sure you use the proper cable size when connecting your batteries so that you do not overheat your connections. For information regarding correct wire sizes you can refer to the National Electric Code, Trojan Battery User’s Guide, or contact Trojan’s live technical support at 800.423.6569.
