Description
The US 31DC XC2 is the largest of the DC series at 130Ah and 620 CCA — built for boats, RVs, and trailers with enough compartment room to take advantage of the extra plate area.
At 13 inches long it won't fit every tray the 24DC or 27DC would, so it's worth measuring before ordering, but for equipment that can accommodate it, the jump in both capacity and cold-cranking amps is substantial.
Why choose the US 31DC XC2
- 130Ah and 620 CCA — the top numbers in the entire DC series
- Best cold-weather starting performance of the three DC case sizes
- Dual terminal configuration for standard marine/RV wiring
- Full-size plates for maximum total energy delivery per battery
