The 12V 100Ah AGM deep cycle battery is one of the most practical capacity sizes for caravan, 4WD, camping, marine and off-grid solar systems. With approximately 1.2kWh of nominal stored energy, it provides useful reserve for customers running multiple 12V loads or wanting longer operation between charging opportunities.

A Popular Size for Touring & Solar

100Ah capacity can suit camping fridges, lighting, water pumps, fans, electronics, communications equipment, device charging and selected inverter loads when the system is correctly designed. It is also a common size for auxiliary-battery installations in caravans, campers, canopies and 4WD touring setups.

Key Features

• 12V nominal voltage
• 100Ah rated capacity
• Approx. 1,200Wh / 1.2kWh nominal energy
• Sealed AGM lead-acid chemistry
• Deep-cycle design for repeated energy-storage use
• Suitable for solar, caravan, camping, 4WD and marine applications
• 12-month warranty

Compatible Charging

Use an AGM-compatible solar controller, mains charger or DC-DC charger. Charging settings must be appropriate for AGM chemistry and within the battery manufacturer's stated limits. Correct cable sizing, fusing and secure battery installation are also important for safe operation.

Understanding Runtime

The 1.2kWh figure is nominal stored energy, not guaranteed usable output. Runtime varies with the load, discharge current, temperature, state of charge, battery condition, cable losses and inverter efficiency. For longer AGM service life, avoid unnecessary repeated full-depth discharge.

If you are building a caravan, 4WD or solar system, StarPower can help match this 100Ah AGM battery with a suitable solar array, MPPT or PWM regulator, DC-DC charger, inverter and protected cabling.
