DS18 INF-28 INFINITE 28Ah AGM Power Cell 12 Volt Battery - 1000W, 840A Max Discharge DS18
The DS18 INF-28 is a 28Ah INFINITE series AGM power cell for car audio systems. It is rated for 1000 watts and can deliver up to 840 amps for 5 seconds, helping hold voltage during heavy amplifier draws.
Absorbed glass mat construction makes it non-spill, so it can be mounted in different positions, including upside down. A higher float charge of 13.5 to 13.8 volts gives extra reserve when the alternator is charging.
L-type terminals with M5 nut and bolt hardware allow add-on terminals and busbars. The battery measures 6.49 x 6.88 x 5 inches, small enough for compact installs.
