Battery Types

Duralast Platinum 34 is an AGM or Absorbed Gas Matt, which is a sealed lead-acid battery. AGM battery is more advanced than the primary lead-acid batteries. It is excellent when it comes to preventing any external vibration. The spill-proof design prevents leakage and needs zero maintenance from your end.

It recharges relatively faster than conventional batteries, undoubtedly a great plus point. Also, it cycles more and provides maximum deep cycle capability and high starting power. Duralast launched this line to meet the different needs of advanced vehicles with their luxurious accessories. Against the essential batteries, it has 2X more cycle life.

Duralast Gold 25-DLG battery is the primary lead-acid battery that is very cost-effective and perfect for any average demanding vehicle. Lead-acid batteries were invented centuries ago, and the technology is matured and well established.

Lead peroxide, sponge lead, and dilute sulphuric acid are the main components that convert chemical energy into electrical energy, and dilute sulphuric acid is the system’s powerhouse. An ideal lead-acid battery has plates, battery terminals, separators, active materials, and containers in the basic construction. One of the most important perks of lead-acid batteries is they can be recycled very easily.

Reserve Capacity

Duralast Platinum 34 battery comes with an impressive reserve capacity of 115 minutes; as per the standards, a reserve capacity ranging from 90 minutes to above is considered the standard reserve capacity for any battery. This battery has a higher reserve capacity which refers to its competency when the engine needs extra backup.

This battery can provide 25 amps of power for almost 115 minutes until the voltage drops to 10.5v. 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.

Though 90 minutes is a standard reserve capacity for any battery, it is quite less than the Duralast Platinum model. The higher the reserve capacity number, the better backup the engine will receive from the battery. Thus when reserve capacity is what you are focusing more on your battery, you know which one to choose.

Cold Cranking Amperage

Duralast 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. When the car starts, the engine needs to provide extra power, and starting off a car always puts pressure on the engine.

Cold-cranking amperage helps the engine prevent a hard start, especially in cold temperatures. 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.

Duralast 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. Like RC, a higher number of cold cranking amperage is preferable for a battery. In extreme weather, high cold cranking amperage is also necessary if the car has a heavier alternator or advanced accessories.


Voltage refers to the power supply the battery can give to the engine or the vehicle’s accessories. Both these batteries have the standard 12v voltage capable of providing enough power to the system.

Group Size

Duralast Platinum 34 belongs to the BCI group size 34; these batteries are used for dual purposes, starting and deep cycles. Automotive, marine, off-the-grid applications, and industrial equipment mostly use this group of batteries.

Duralast Gold 25-DLG belongs to the BCI group size 25. Any battery labeled as this group size can be considered its equivalent replacement. This group of batteries is usually heavier in size. It has the most significant number of plates and grids permitted in a battery.


Both the models feature the same time frame of warranty which is three years of replacement warranty. Though other brands have more warranty limits, three years of warranty is quite a deal, along with the excellent name of Duralast in durability.

Dimensions LxWxH

Battery dimension is another factor you should consider while buying a battery; a more extensive battery will not physically fit in your car. So if the space in your engine bay is limited, then you must choose the smaller battery. Duralast Platinum 34 battery dimensions are 10.94 x 6.89 x 8.19 inches, and it weighs 61.7 pounds.

Duralast Gold 25-DLG battery dimensions are 10 ax 6.88 x 8.75 inches, and it weighs 70.55 pounds. As you can see, the Duralast Gold battery is bigger; thus, it will not fit in every car. If the space in your engine bay is limited, you must consider this factor while choosing any of these batteries.

Terminal Location

Both the models feature the exact positive terminal location on the top left side of the battery. And the opposing corner is on the top right corner of the battery.

Our Observation

The main difference between Duralast Platinum and Duralast Gold is reserve capacity. Duralast Platinum 34 battery has an impressive reserve capacity of 115 minutes, while the Duralast Gold 25-DLG features 90 minutes of reserve capacity. So if you are looking for a battery with a better backup, then Duralast Platinum is the way to go.

Otherwise, both these batteries are quite identical in features and performance. Choosing between these two is difficult but the Duralast Platinum 34 is just the updated or the advanced form of the Duralast Gold 25-DLG. Thus for advanced vehicles, Duralast Platinum 34 is a better choice. But in case you have average requirements and want a battery within budget, nothing can beat the Gold series.
