D4900 [Used]

The XS Power D4900 is a sealed 12V AGM power cell, sized as a direct BCI Group 49 replacement for many domestic and European models, including Land Rover, Audi, and GMC. Absorbent Glass Mat construction suspends the electrolyte in fiberglass, so it mounts in almost any orientation and resists spills, moisture, and vibration on rough roads. Low internal resistance lets it deliver 1,250 cranking amps and 1,100 cold cranking amps, so the engine starts in extreme heat or deep cold. 100Ah of capacity and 178 minutes of reserve capacity leave room for accessories once the engine is running. As a primary battery it supports systems up to 3,000W; wired as a dedicated secondary battery it handles 4,000W, holding voltage steady when amplifiers pull hard on low notes. It suits large SUVs and trucks that already carry a heavy factory electrical load plus aftermarket amplifiers. M6 terminal hardware is included for ring terminals and large-gauge power wire. The D4900 carries a three year warranty.
