Like batteries for cars, truck batteries belong in one of two general classifications: Flooded wet cell and Valve Regulated Lead Acid (VRLA) batteries. The former utilizes lead plates and a liquid or gel-type electrolyte solution to produce an electrical charge. Meanwhile, VRLA batteries are sealed, low-maintenance units that typically use an absorbent glass mat (AGM) design, offering better performance than a typical wet-cell battery.

Best Truck Batteries: Our Preference

When it comes to trucks and SUVs, we usually recommend an AGM battery. AGM batteries have fiberglass separators or glass mats that 'absorb' the electrolyte solution inside the battery. On average, AGM batteries can charge five times faster, last two to three times longer, and cycle down to 80 percent of their DoD or Depth of Discharge (a percentage of the battery that can be drained without damaging the cells).

#1: Optima Batteries -003 34/78 RedTop

Leading our list of best truck batteries is the Optima RedTop. Optima Batteries feature the brand's proprietary Spiral Cell technology to deliver reliable performance in hot and cold weather.

Best Truck Batteries: Tips & Resources

When choosing a new battery for your truck, here are some factors to keep in mind:

Price

Standard wet cell batteries are more affordable than VRLA or AGM batteries. But then again, AGM batteries last longer. Wet cell batteries are good enough for most stock applications if you want the best bang for your buck. Consider upgrading to a more robust (yet costlier) AGM battery if you have a modified work truck or off-road machine.

Cranking Amps & Cold Cranking Amps (CCA)

Cranking amps measure the number of amps the battery can deliver for 30 seconds of cranking at 32°F (0°C). It refers to the amount of power required from the battery to start the engine, so the exact number depends on the type of truck and the engine size. For example, big engines need more cranking amps.

On the other hand, the cold cranking amps (CCA) refers to the number of amps that a battery can expel for 30 seconds at 0°F or -18°C. The CCA designation measures how well a battery can start your truck's engine in frigid weather. In most cases, a higher CCA number means the battery takes less effort (and less time) to start the engine.

Reserve Capacity

The reserve capacity refers to the number of minutes a battery can deliver a constant 25 amps of current at 80°F before the battery is discharged down to 10.5 volts. It helps to buy a truck battery with a higher reserve capacity if your vehicle has loads of accessories that require extra power. This can include things like a winch, off-road or auxiliary lights, or an upgraded audio system.

Group Size

Automotive batteries come in many group sizes and designs, including standard top-post, recessed top-post, and side-post batteries. For instance, most Japanese and American vehicles utilize top-post battery fitments, while European car brands generally use recessed top-post battery designs.

Check the owner's manual of your truck to determine the correct battery group size. Choosing the wrong battery size may cause a spark or fire when the battery post contacts a metal part of the vehicle, so keep this in mind.

Portable Jump Starters

It's a good idea to keep a portable jump starter handy, as even the best batteries will eventually run out of juice. If you have a truck with a smaller displacement diesel (3.0-liters or less), this Shell A unit will work. If you have an HD truck, take a look at this HOMPOW unit instead.

Regular Maintenance

Whether you're in a truck built for overlanding or living the van life, one of the critical components for any adventure is having a reliable and durable power source. 

When access to electricity is unavailable, dependable and robust power sources are necessary to keep critical equipment running, including powered coolers, electric gadgets, or even to jump-start a starter battery. Batteries and battery accessories play a significant role in keeping your devices powered up and your rig ready to start.

Most dual battery systems may include a dual battery tray, a deep-cycle battery, a battery isolator, a battery monitor, a battery charger, and the correct wiring and fuses.

These components will ensure that your dual battery system is reliable, durable, and safe. This gear guide showcases some of the latest options for batteries and battery accessories to ensure you have plenty of power once you get to your destination.

The Dual Battery Checklist: 7 common items needed for most dual battery setups.

Dual battery setups such as the one in our Land Cruiser project vehicle require specialized equipment. This list of seven items is required for most common setups.

1. Dual Battery Tray
The first step in setting up a dual battery system is to get a dual battery tray. This tray is specifically designed to fit two batteries in your vehicle's engine bay or cargo area. It provides a secure and sturdy platform for the batteries, ensuring that they stay in place even on rough terrain. 

2. Deep Cycle Battery
The next step is to choose a deep cycle battery. These batteries are specifically designed to provide sustained power over long periods. They have a high capacity and can be discharged and recharged multiple times without damage. AGM (absorbed glass mat) batteries are a popular choice for overlanding, as they are maintenance-free and have a long lifespan.

3. Battery Isolator
A battery isolator is an essential component of a dual battery system. It ensures that the primary battery is not drained while powering your accessories. It allows the secondary battery to be charged from the alternator while preventing the power from draining from the primary battery. 

4. Battery Monitor
A battery monitor is a device that keeps track of the status of your batteries. It provides real-time information on the charge level, voltage, and temperature of your batteries. A battery monitor is an essential tool for overlanding, as it allows you to monitor the state of your batteries and prevent over-discharging.

5. Battery Charger
A battery charger is necessary to recharge your batteries when they are depleted. You can choose between a solar-powered charger or a dual-battery system that allows you to charge your battery while driving.

6. Inverter
An inverter is an accessory that allows you to convert DC power from your battery to AC power. This accessory is useful if you need to power appliances that require AC power.

7. Wiring & Fuses
The wiring and fuses are crucial components of a dual battery system. You need to ensure that the wiring is of the correct gauge and that the fuses are rated correctly. Poor wiring and incorrect fusing can cause your battery system to fail or even cause a fire.
