November 2026 Special: Group 31 Truck and Equipment Batteries

When temperatures drop, weak batteries show up first. This November, Pak Petroleum Marketing is offering 10% off all Group 31 batteries for semi trucks, heavy equipment, and commercial vehicles. In Texas, hard freezes often arrive in mid December, so November is the window to replace borderline batteries before the first cold snaps. Stock replacements now to reduce roadside calls and keep fleets on schedule through winter.

Group 31 Batteries for Semi Trucks and Heavy Equipment

Group 31 batteries are the standard footprint for Class 8 tractors, medium duty trucks, and a wide range of agricultural and construction equipment. With cold cranking amps in the 930 to 950 range, these batteries deliver reliable cold starts, stable voltage for overnight hotel loads, and consistent performance under heavy accessory draw.

All models listed include an 18-month warranty and are compatible with typical fleet maintenance programs. If your equipment uses dual or triple Group 31 configurations, plan replacements in sets to keep banked batteries balanced.

• Clean terminals and secure cabling to reduce voltage drop
