This group of batteries is usually heavier in size. Any battery labeled as this group size can be considered its equivalent replacement. Automotive, marine, off-the-grid applications, and industrial equipment mostly use this group of batteries.ĭuralast Gold 25-DLG belongs to the BCI group size 25. Both these batteries have the standard 12v voltage capable of providing enough power to the system.ĭuralast Platinum 34 belongs to the BCI group size 34 these batteries are used for dual purposes, starting and deep cycles. Voltage refers to the power supply the battery can give to the engine or the vehicle’s accessories. In extreme weather, high cold cranking amperage is also necessary if the car has a heavier alternator or advanced accessories. Like RC, a higher number of cold cranking amperages is preferable for a battery. We all know the hassle of starting a car when the temperature is extreme a battery with higher cold cranking amperage diminishes the hassle to zero.ĭuralast Gold 25-DLG has 550 amps of cold cranking amperage which means this battery will provide 550 amps of starting power to the combustion engine for 30 seconds at 0F temperature. When the car starts, the engine needs extra power, and starting off a car always puts pressure on the engine.Ĭold-cranking amperage helps the engine prevent a hard start, especially in cold temperatures.

Thus when reserve capacity is what you are focusing more on your battery, you know which one to choose.ĭuralast Platinum 34 has 740 amps of cold cranking amperage this battery supplies 740 amps of cold cranking amperage to the engine at 0F temperature for 30 seconds. The higher the reserve capacity number, the better backup the engine will receive from the battery.

Though 90 minutes is a standard reserve capacity for any battery, it is less than the Duralast Platinum model. Duralast Gold 25-DLG, on the other hand, features 90 minutes of reserve capacity which means this battery can provide 25 amps of power to the engine for 90 minutes straight. Lead-acid batteries were invented centuries ago, and the technology is mature and well-established.ĭuralast Platinum 34 battery can provide 25 amps of power for almost 115 minutes until the voltage drops to 10.5v. The spill-proof design prevents leakage and needs zero maintenance from your end.ĭuralast Gold 25-DLG battery is the primary lead-acid battery that is very cost-effective and perfect for any average demanding vehicle. It is excellent when it comes to preventing any external vibration. AGM battery is more advanced than primary lead-acid batteries. Duralast Platinum 34 is an AGM or Absorbed Gas Matt, a sealed lead-acid battery.
