ā” HIGH-OUTPUT ENGINE STARTING PERFORMANCE
The Optima REDTOP 75/25 is designed first and foremost as a starting battery.
Its supplied 720CCA rating provides high cranking output for applications where rapid, reliable engine starting is required.
This makes it particularly useful for compatible vehicles operating in demanding conditions or installations exposed to vibration.
š 720CCA COLD CRANKING CAPACITY
Cold Cranking Amps: 720CCA
The CCA rating represents the batteryās ability to provide high current during engine starting under specified cold-temperature test conditions.
The required CCA should always be checked against the vehicle manufacturerās battery specification before installation.
š OPTIMA SPIRALCELL TECHNOLOGY
Optima REDTOP batteries use SpiralCell Technology rather than conventional flat-plate battery construction.
The supplied product information specifies:
- Spiral-wound cell construction
- 99.99% pure lead
- Strong starting-current delivery
- Consistent electrical performance
- High resistance to vibration
The spiral design is intended to provide a robust internal battery structure for demanding vehicle applications.
š”ļø AGM ā ABSORBENT GLASS MAT CONSTRUCTION
The REDTOP 75/25 uses AGM battery technology.
AGM construction holds the electrolyte within absorbent glass mat separators rather than leaving free-flowing liquid inside the battery case.
This supports:
- Maintenance-free operation
- Non-spillable construction
- Strong vibration resistance
- Flexible installation options
- High starting-current capability
šŖ HIGH VIBRATION RESISTANCE
The supplied product information states that Optima REDTOP batteries can be up to 15 times more vibration resistant than standard flooded batteries.
This makes the REDTOP design particularly attractive for compatible 4WDs, utes and other vehicles regularly exposed to corrugations, rough roads or equipment vibration.
ā ļø IMPORTANT: Even a vibration-resistant battery must still be secured correctly using a suitable battery tray and hold-down system.
ā±ļø LONG-LIFE DESIGN
The supplied product information states that REDTOP batteries are designed to last up to three times longer than conventional flooded batteries under applicable operating conditions.
Actual battery service life depends on factors including:
- Charging-system voltage
- Temperature
- Depth of discharge
- Vehicle electrical loads
- Storage conditions
- Installation quality
- Frequency of use
š FAST RECHARGE CAPABILITY
The REDTOP 75/25 is designed for strong charge acceptance following engine starting.
This can help restore the energy used during cranking efficiently when the vehicle charging system is operating correctly.
ā ļø IMPORTANT: Ensure the vehicle charging system is suitable for an AGM starting battery and operates within the battery manufacturerās required charging parameters.
š 44AH C20 CAPACITY
Supplied C20 capacity: 44Ah
The C20 rating represents the battery capacity measured over a 20-hour discharge test under specified conditions.
Although the REDTOP 75/25 carries an Ah capacity rating, it is designed primarily as a high-cranking starting battery rather than as a dedicated deep-cycle auxiliary battery.
ā³ 90-MINUTE RESERVE CAPACITY
Supplied reserve capacity at 25A: Approximately 90 minutes
Reserve capacity provides an indication of how long the battery can support a specified electrical load under applicable test conditions.
Real-world runtime will vary depending on load, temperature, battery condition and state of charge.
š« STARTING BATTERY ā NOT A DEDICATED DEEP-CYCLE BATTERY
The Optima REDTOP 75/25 is designed primarily for engine-starting applications.
Its key strength is delivering high cranking current for ignition rather than repeatedly supplying deep discharges to auxiliary equipment.
ā ļø IMPORTANT: Do not select the REDTOP 75/25 as a dedicated deep-cycle auxiliary battery unless the intended application has been confirmed as suitable. Repeated deep discharge is not its primary design purpose.
š§° MAINTENANCE-FREE OPERATION
The AGM construction means there is no routine requirement to top up electrolyte with water.
This simplifies ownership compared with conventional serviceable flooded batteries.
š§ NON-SPILLABLE CONSTRUCTION
The AGM design is supplied as completely non-spillable under normal operating conditions.
This provides additional installation flexibility compared with conventional flooded batteries containing free liquid electrolyte.
ā ļø IMPORTANT: Always install the battery in accordance with the battery and vehicle manufacturerās requirements, including restraint, ventilation and permitted orientation.
