Trucks are often a key part of business operations. From carrying supplies and equipment to transporting workers, they are needed for a wide variety of roles. That is why it is imperative that they are kept in perfect working condition to avoid any delays in work. One of the key aspects of a well-maintained truck is having the right truck battery. Just like a car battery, the truck battery has its own set of specifications. After the voltage rating of the battery, the Ampere-hour rating (Ah) of the battery is perhaps the most important of them. Commonly called amps, it is a common question that how many amps does a truck battery have. For all our truck owning customers, BPZ would address this question and add valuable details that support the question.

Before discussing the amps of the truck, let us have a quick overview of Ah rating. It is basically the amount of current the battery can provide for certain amount of time. For example, if the Ah rating or amps of the battery is 130 Ah then it means that the battery can provide a current of 130 A for 1 hour.

Truck can be a fairly broad category. Smaller pickups and large commercial freightliners both can be technically categorized as trucks. That is why it is harder to give a definitive value for the number of amps the truck battery would need to provide. Generally speaking, a smaller truck battery would have an average number of amps similar to that of a car battery which could be in the range of 70-100 Ah. On the other hand, larger commercial trucks can have average amps of around 200 Ah. This shows the diversity of the trucks and why it is important to understand the Ah rating of the truck battery.

A truck can be compatible with a range of amps rating given that the battery has a 24V rating. There are certain benefits that a truck can enjoy if the battery has a higher amps rating. One of the most common benefits is that the alternator life can be extended. This is because the higher amps rating would mean that battery needs to recharge less frequently which would reduce the workload of the alternator. Furthermore, the electronics of the truck would not be underpowered and be able to function properly without any issues.
