INF-100 INFINITE 100 AH AGM Power Cell 12 Volt Battery

DS18 INF-100 INFINITE 100Ah AGM Car Audio Battery

Add reserve capacity to a properly designed car-audio electrical system with the DS18 INF-100, identified as INF-100AH in DS18's specifications. This maintenance-free, non-spillable AGM power cell provides 100Ah of rated capacity for installations that need additional battery reserve.

Key Specifications

• Battery technology: Absorbed Glass Mat (AGM)
• System type: 12V battery; manufacturer-listed nominal voltage 12.8V
• Rated capacity: 100Ah at the 10-hour rate to 1.8V per cell at 25°C / 77°F
• Manufacturer system-support rating: 2,800 watts
• Maximum discharge current: 1,200A for 5 seconds, not a continuous-current rating
• Battery group: 31
• Construction: Maintenance-free and non-spillable
• Country of manufacture: Vietnam

What the 2,800-Watt Rating Means

DS18's 2,800-watt figure is a system-support rating, not amplifier output or a guarantee that voltage will remain constant at that load. Actual performance depends on amplifier demand, charging capacity, wiring, battery condition, and listening habits. Added battery capacity does not replace adequate alternator output or correct electrical-system design.

Charging and Terminal Planning

• Float charging voltage: 13.5–13.8V at 25°C / 77°F
• Manufacturer-listed maximum recommended charging current: 30A
• Listed nominal operating temperature: 25°C ±3°C / 77°F ±5°F

Use AGM-compatible charging equipment and follow DS18's instructions. Float voltage is a maintenance-charge specification, not a blanket setting for every charging stage.

Confirm terminal hardware before ordering accessories: DS18's technical table lists recessed threaded lead-alloy M6 bolt terminals, while its product overview says M5. Verify the hardware on the supplied battery before selecting bolts, terminals, or busbars.

Mounting and Heat Warning

DS18 states that the sealed, non-spill design permits multiple mounting orientations, including upside-down mounting. Secure the battery properly and protect the terminals against accidental contact.

Mount away from heat sources. DS18 warns against installation in or near engine bays because heat can cause swelling, particularly in hot climates. Use an appropriate cabin, trunk, or bed location instead. Confirm dimensions, hold-down fit, terminal clearance, and cable routing before installation; Group 31 identification alone does not guarantee vehicle fitment.
