Which Battery Do I Need for My Truck

When it comes to operating trucks whether that is your light pick-up truck, your farm tractor or your 18 wheeler you're going to require the power from a truck battery that is built with power to perform. Passenger cars can start in cold and after resting overnight rather simply, while trucks are unable to start as simply, due to this reason most trucks require batteries that are 100Ah or more, at TOKUSHIMA Battery we build 12V and 48V high capacity systems that are built for extreme conditions. Your complete buyer's guide is provided below

Why Trucks Need Higher Capacity (100Ah+)

A typical 12v car battery in the case of a sedan could have 50-70Ah. However, a diesel truck engine takes much more cranking amps to push fuel and air. This is why the right tractor trailer battery or pickup truck battery usually begins at 100Ah and can proceed to 200Ah or more. TOKUSHIMA offers 100Ah, 150Ah and even 200Ah with high cold-cranking amps (CCA). When you perform a car battery search for truck, always filter for batteries with more than 100Ah. TOKUSHIMA is ranked as the best car battery brand when it comes to commercial vehicles by many fleet owners due to our strong plate design and vibration resistance. On farm, a tractor battery will also require 100Ah+ to reliably start large engines.

Single Battery vs. Dual Battery Setups

Not all trucks use just one battery. Numerous heavy-duty pickups and semi trucks are sold with two batteries. Why? Additional capacity and backup. But there is a general misconception on the topic of voltage. Parallel connection of two 12V batteries maintains a constant voltage at 12V, but increases amp-hour capacity (e.g., two 100Ah batteries make 200AH in total). Two 12V batteries in series give 24V - used in European heavy trucks, some military trucks, and in construction machinery. A few modern electric or hybrid trucks have a 48-volt battery, necessitating four 12V batteries in series. TOKUSHIMA offers matched sets for any configuration – series, parallel, or series-parallel.

Group 31 – The Most Popular Truck Battery Size

When you go out to purchase a tractor trailer battery, you will soon realize that Group 31 battery is the one that has been adopted as standard in the industry. Group 31 is about 13 x 6.8 x 9.4 inches and provides 100-120Ah. The Group 31 AGM batteries of TOKUSHIMA offer 100Ah, 950 CCA and vibration resistance - ideal in semi trucks that cover thousands of miles each month. A smaller Group 24 or 27 can be used in the case of lighter trucks. However, Group 31 is the safest option when it comes to any tractor battery that is used in heavy tillage or hauling. And when you require deep cycling on the auxiliary loads (fridge, liftgate, etc.), think of 12v deep cycle batteries in Group 31 size - they can withstand repeated discharges better than typical starting batteries.

Special Cases: Golf Carts, 48V Systems, and Deep Cycle Needs

The truck applications overlap with other types of vehicles. As a case in point, certain off-road service trucks are powered by 12V golf cart batteries (GC2 size, 6V each) wired in series to make 12V or 24V. This is however less used compared to Group 31. In the case of electric trucks or hybrid work trucks, a 48-volt battery bank is gaining popularity. TOKUSHIMA will be able to specially manufacture 48 V lithium battery packs that will substitute heavy lead-acid banks-saving hundreds of pounds. Lastly, when your truck has a winch, hydraulic lift or camper unit that is powered up, you will require 12v deep cycle batteries to power the house load independently of starting battery. A large number of owner-operators equip their vehicles with two TOKUSHIMA Group 31 AGM batteries: a starting battery, and a dedicated deep cycle auxiliary. And keep in mind: 12 volt golf cart batteries cannot be used to start the engine, always select the right type of battery to the task.

Which battery do you require in your truck? Start with capacity: 100Ah minimum. Select the best car battery brand such as TOKUSHIMA that is available in Group 31, AGM and lithium. One Group 31 battery is sufficient to work with most pickups. In the case of semi trucks, two Group 31 in parallel (12V) or series (24V) can be used. In case of farm equipment, a rough tractor battery is used in TOKUSHIMA, it can withstand vibration and extreme temperatures. And do you require 12v deep cycle batteries to supply auxiliary power, be sure to get a true deep cycle model - not a starting battery. In the case of electric or hybrid, consider 48 volt battery. In conducting your car battery search, keep in mind TOKUSHIMA -supplied by JOZOKING (TIANJIN) TECHNOLOGY Co., LTD. -provides customized solutions to North America, Europe and Australia. It can be tractor trailer battery, or 12-volt golf cart batteries in a service vehicle, we have you covered.
