9 Best Group 31 Commercial Truck Batteries in 2026

The trade-off is weight: at 58.3 pounds, this battery is noticeably heavier than lithium options like the YOLIQUE LiFePO4, which weighs less than half as much. That extra mass comes from the dense lead plates and reinforced case that make it tough. But it also means more strain on your back during installation and less flexibility if you’re trying to shed pounds from your truck. If you prioritize drop-in ease and a proven track record over ultralight weight, the ACDelco Gold is a straightforward choice for compatible commercial trucks.

A 950 cold cranking amp rating puts this Crown battery near the top for sheer starting power in a Group 31 commercial truck battery. That means it can spin a big diesel engine even on a bitter morning when the oil is thick and the glow plugs are working hard. The 100Ah reserve capacity also gives you a solid backup for running lights, inverters, or overnight cab accessories without draining the battery flat. This is a battery built for heavy-duty work, with a sealed AGM design that shrugs off vibration and never needs water checks, so it fits well in trucks that see rough roads and long hours.

Weight is a real factor here. At 76 pounds, this Crown is heavier than several Group 31 competitors, such as the OPTIMA YellowTop D31T at 59.8 pounds and the Mighty Max MM-G31 at 57.6 pounds. That extra mass comes from thicker plates and more lead, which is what gives it the high CCA and vibration resistance. But it also means more strain on your back when you wrestle it into the battery tray. If your truck has a tight engine bay or you swap batteries often, that weight is a real consideration. For someone who prioritizes raw cranking power and durability over easy handling, this Crown delivers where it counts.

A 155-minute reserve capacity means this battery keeps your truck’s electronics running long after the engine shuts off. That matters when you’re idling at a job site or running auxiliary lights through a long night. That’s the reason it takes the top spot for vibration resistance here: commercial trucks shake, rattle, and bounce down rough roads, and a battery that can handle that abuse without internal damage saves you from being stranded. It suits anyone who needs a maintenance-free, tough-as-nails group 31 for a work truck that sees real miles and real punishment.

Weight and starting power are the main considerations here. At 59.8 pounds, this is a heavy battery to lug into place, especially compared to lithium options like the YOLIQUE LiFePO4 that weigh less than half as much. And while 900 cold cranking amps is plenty for most diesel trucks, the Crown Battery CRV31S AGM offers 950 CCA if you need that extra margin on a cold morning. The YellowTop’s dual-purpose nature means it balances starting and deep-cycle use, but it won’t deliver the same deep-cycle endurance as a dedicated marine battery. For a straight-up workhorse that prioritizes vibration survival over outright cranking power, this is a smart, proven pick.

A 1200-amp peak cranking rating means this battery fires up semi trucks and heavy-duty diesels without breaking a sweat, while its 120-amp continuous output keeps inverters, fridges, and winches running all day. That dual-purpose design replaces both your starter and house battery in one Group 31 footprint, so you can ditch the lead-acid weight and gain lithium longevity. The self-heating panels kick in automatically at 32°F, keeping it chargeable and cranking through freezing winters, and the Bluetooth app lets you check state of charge, voltage, and temperature from your phone. For commercial truck owners who want a single battery that handles cold starts and deep cycling, this is the setup that cuts weight and boosts runtime.

The catch is that these batteries only work in parallel 12V systems, if you need 24V, 36V, or 48V for a custom setup, you will have to look elsewhere.

130 amp-hours of capacity and 185 minutes of reserve power mean this battery keeps your equipment running long after others have quit. That deep-cycle design lets you drain and recharge it repeatedly without losing performance. It’s ideal for trolling motors, RV house banks, or backup power systems where sustained output matters more than a quick burst of cranking amps. It’s a straightforward flooded lead-acid battery, made in the USA, and sold as a set of two.

Flooded batteries need a little attention, checking water levels and keeping the terminals clean, so if you want a truly maintenance-free setup, you might lean toward an AGM like the Crown CRV31S. But for the price-conscious operator who values raw capacity and doesn’t mind a bit of upkeep, the 31HDC delivers strong amp-hour ratings for its type. At 67 pounds per battery, it’s heavier than some AGM options (like the ACDelco Gold at 58.3 pounds) but lighter than others (like the Crown CRV31S at 76 pounds), so plan your mounting accordingly. This is a workhorse, not a set-and-forget solution, and it rewards the hands-on owner.

With 900 cold cranking amps, this battery delivers strong starting power for vehicles that need a reliable jolt in any season. The 140-minute reserve capacity provides extra run time if the alternator is not charging, giving you a buffer for short-term accessory use. The sealed AGM construction is spill-proof and resists vibration, so it holds up on rough roads and can be mounted in multiple positions. For anyone who needs a dependable starting battery without extra frills, this model covers the basics well.

At 57.6 pounds, this battery is heavier than some competing group 31 options, the Coulomb Solutions sodium-ion battery, for example, weighs only 24.0 pounds. That weight difference matters if you’re swapping batteries frequently or have a tight engine bay. The positive terminal sits on the left and the negative on the right, so check your vehicle’s cable orientation before buying. Compared to the ACDelco Gold 31AGMT, the Mighty Max uses the same AGM technology and similar dimensions but typically costs less, which appeals to anyone who wants strong cold cranking amps without spending extra.

1150 cold cranking amps and 2150 pulse hot cranking amps mean this battery can start a big diesel even when the temperature drops. The 205-minute reserve capacity lets you run lights or a lift gate for hours with the engine off. That combination of cranking muscle and deep reserve makes it a natural fit for heavy-duty commercial trucks that need both reliable starts and sustained accessory power.

Measuring 15.2 inches long and weighing 79 pounds, this battery demands a spacious, secure mounting location. The Group 31 case with brass SAE posts and threaded stainless steel stud terminals provides flexible connection options for both top-post and ring-terminal setups. Owners should verify their tray can accommodate the length and weight before purchase, as the extra mass helps reduce vibration in heavy-duty applications. The right-side negative terminal placement also requires checking cable routing compatibility. These physical characteristics make it best suited for vehicles or equipment with dedicated battery compartments rather than cramped installations.

A 210-minute reserve capacity means this battery can keep your truck’s electronics running for over three hours at a 25-amp draw. That’s a huge safety net if you’re idling with lights, a liftgate, or a diesel heater on a cold night. That reserve capacity is paired with a 105 amp-hour rating, so you get sustained power for long-haul stops or overnight parking without worrying about a dead start in the morning. It’s built for the driver who values endurance over peak cranking punch, and the dual terminal setup (autopost and stud) makes it easy to wire into older trucks or custom setups without adapters.

Weight is a real factor here: at 67.5 pounds, this is one of the heavier group 31 batteries, so expect a bit more strain during installation or if you’re swapping batteries on the road.

With 1200 cranking amps, this battery fires up engines reliably. Its 120 Ah deep-cycle rating keeps accessories like a fridge or trolling motor running for hours. The QUAD terminals give you extra connection points for add-ons without cluttering the posts, and the smart battery management system sends alerts to your phone via an app, so you can monitor charge and health remotely.

The warranty on this battery covers non-commercial use with 24 months of free replacement, but automotive use is not covered. At 43.2 pounds, it’s lighter than many traditional Group 31 batteries, which makes handling and installation easier in tight engine compartments. For boaters, RV owners, or off-grid users who want lithium performance and the ability to monitor battery status through a smartphone app, this is a practical choice. Just be aware that commercial use drops the warranty to 12 months.
