Guidance
When selecting a battery tender for your diesel truck, there are a few factors to consider. The first is the voltage of your truck’s battery. Diesel trucks typically have 12-volt batteries, so you’ll want to make sure the battery tender you choose is compatible with this voltage.
Another consideration is the size of your truck’s battery. Some battery tenders are designed for smaller batteries and may not be powerful enough to properly charge a larger battery. Look for a battery tender with a higher amperage rating if you have a larger battery.
Finally, consider the environment where you’ll be using the battery tender. If you’ll be using it in a garage or other enclosed space, you may want to choose a battery tender with a built-in fan to prevent overheating.
