How to Choose the Best Batteries for Diesel Truck
If you are about to purchase a new battery for your diesel truck then you want to make sure that you consider the following things about the battery and the vehicle so you can buy the best battery for your particular needs.
- Does your truck require 2 batteries? If this is the case you want to make sure that both of the batteries on the truck are of the same size and has the same cranking abilities. You do not want one battery to be a lot more powerful than the other battery. A lot of people also like to change both batteries at the same time so they have batteries with the same cranking power of the same age.
- The way to decide the number of cranking amps that you have to have is to consider how many things you have pulling off of the battery while it is cranking the vehicle. You need more cranking amps for vehicles that have more electronic accessories that require power from it. Of course you know to consider things like cell phone chargers, DVD players, GPS systems, and radios, but you should also consider things like heated seats, the a/c or heating, the fan motors, the dome light, the bells and warning whistles, power windows, power seats, and after market items like fog lights, or lights on top of the vehicle.
Another thing for you to consider is the type of battery you are buying and the areas where the vehicle will be used.
The cold drains the energy from batteries and some batteries will even freeze and crack in extreme temperatures. Consider the climate where you live when you are selecting a battery for your vehicle.
Maintenance Free Batteries
The newer batteries like the absorbed glass material or AGM batteries are sealed batteries that do not require you to do any maintenance to keep them working properly. The older lead acid batteries do require maintenance, and the older lead acid batteries are more dangerous to have on your vehicle because the fluid inside the battery can leak out if the battery is cracked or damaged.
Vibration Problems caused by Rough Terrain
If you drive on a road that is not perfectly smooth then your battery can be vibrated and this can cause the battery to become disconnected or discharged. Make sure you buy a battery that has a good dependability rating when driven under circumstances that cause a lot of vehicle vibrations.
Our experts all agree that the best batteries for diesel trucks are the ones that are:
- Maintenance free
- Have a lot of cold cranking amps
- Are durable
- Can withstand vehicle vibrations
- Are cold tolerant
- Are heat tolerant
- Are versatile and fit in many vehicles
- Can stand to be charged repeatedly without compromising the integrity of the battery
You want to buy a battery from a reputable dealer, and one that is manufactured by a reputable manufacturer.
