What battery is best for a diesel car?

The specifics of the diesel engine have a direct impact on the battery requirements. If the battery is incorrectly selected, starting problems are likely to occur. Let’s consider in detail, what battery is better to buy for the diesel engine and why.

What battery is necessary for a diesel engine and why?

In comparison with the gasoline engine, the diesel engine has a number of features that determine the requirements for the battery. Briefly consider them.

  1. Firstly, a higher degree of compression in the cylinders: in the gasoline engine the ignition occurs from the spark plug, and in the diesel engine the combustion chamber heats up before the fuel injection due to the compression of the air in it. This requires the creation of high pressure in the cylinder, to overcome the resistance of the compressed air. Therefore, more force is needed to turn the diesel engine crankshaft.
  2. Secondly, the need to warm up the air in the cylinders with glow plugs (in winter). Glow plugs have a fairly high power, which determines the significant power draw from the battery even before turning on the starter.
  3. Third, thick oil. Diesel lubricants are generally more viscous. The difference with gasoline oils becomes especially noticeable at low temperatures. Due to the thicker lubricant, viscous friction in the contact spots increases, which the starter will require additional power to overcome.

These factors have the greatest influence on which battery to choose for the diesel. It is obvious that with the same volume, a diesel engine will need a more powerful battery than a gasoline engine for a guaranteed start.

Best diesel truck battery for cold weather

Optima RedTop batteries are intended for use as common engine starting batteries where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed. This would describe most stock vehicles.

RedTop batteries are optimized for delivering high currents during very short periods of time, typically from few seconds to 20, perhaps 30 seconds.

They are not intended for cycling use in any application and regular deep discharge cycling use can shorten their operating life significantly.

If you occasionally listen to the music in your car for shorter periods of time (10-20 minutes) while the engine is not working, but without trying to fry your sub-woofers and other speakers, Optima RedTop batteries can handle such load. If you like to listen to the loud music or there are similar demands for electric power while the engine is not working, consider YellowTop batteries.


  • Strongest starting burst
  • Up to 3X longer life
  • 15 times more vibration-resistant
  • Virtually spill proof
  • Mountable in virtually any position
  • Maintenance-free
  • Faster recharging
  • Optimal starting power

How to choose the best battery for diesel trucks

When it is time to look for a new battery in your diesel vehicle, you may keep some important points in your mind before you start your search.

For the cases with high loads on the battery you may think of even a dual battery system or look for a single battery with sufficient capacity.
