What to consider when buying a truck battery?

If you're in the market for a new truck battery, you have a few things to consider. One is the type of battery you need. There are several types on the market, including standard lead-acid batteries, gel batteries, and Absorbed Glass Mat (AGM) batteries.

AGM batteries are becoming increasingly popular due to their many benefits. AGM batteries are made with a glass mat separator that absorbs the electrolyte. This design provides several advantages over other types of batteries.

  • First, it makes them spill-proof, so you don't have to worry about electrolytes leaking out if the battery is tipped over or damaged.
  • Second, it prevents corrosion on the terminals, meaning the battery will last longer and require less maintenance.
  • Third, AGM batteries can handle more recharging and discharging cycles than other types of batteries, meaning they'll last longer overall.
  • Fourth, they're less likely to sulfate, which is a common cause of battery failure.
  • Finally, AGM batteries are much better for the environment since they don't contain lead or other harmful chemicals.

Other factors to consider when choosing a truck battery include the size of the battery, the warranty, and the price.

Size is important because you need to ensure the battery will fit in your truck. The warranty is important because it gives you some peace of mind in case the battery fails prematurely.

And the price is always a consideration when making any purchase. But remember that a truck battery is a long-term investment, so you want to make sure you get the best quality battery you can afford.

How long should diesel truck batteries last?

The lifespan of a diesel truck battery depends on several factors, including the brand of battery, the type of battery, and the way it's used. AGM batteries tend to last longer than other types of batteries, and batteries that are regularly taken care of (by being properly maintained and kept clean) tend to last longer than those that aren't.

In general, most batteries should be able to last 3-5 years with regular use. However, if a battery is used heavily or is not taken care of properly, it may only last for 1-2 years.

What size battery do I need for a diesel truck?

It depends on the truck. Some smaller diesel trucks may only require a 6-volt battery, while some larger trucks may require a 12-volt or 24-volt battery. Be sure to consult your truck's owner's manual to find the specific battery size that is recommended for your vehicle.


Finding the best diesel truck batteries should be the top priority for any truck owner. Not only do these batteries provide the power needed to start the engine, but they also help to keep it running smoothly. The recommended brands mentioned earlier are not the only ones available on the market, but they are definitely some of the best and will serve as your starting point in your search for the perfect battery.

When it comes to choosing the right battery for your diesel truck, make sure to do your research and read reviews. This way, you can be sure that you're getting a quality product that will last.
