A lot of drivers care about the other parts of their cars, especially the outward appearance, and forget to take cognizance of the battery. 

Do not feel pressured about getting your car’s bad battery replaced. Why? Because you are not alone in the struggle. Throughout a complete life cycle of a vehicle, it is expected that the battery will be replaced at least once or twice. So it is completely normal to change a vehicle’s battery.

Duralast Battery vs Interstate Battery

The three major factors to differentiate the two battery brands are;

Overall, the Interstate battery has a better battery life as compared to the Duralast battery. This is because of its low discharge rate. Hence, it’s more reliable.

The Core Charge Periods

Even though the Duralast battery models are not reliable as regards their battery life. They are, however, better in terms of the Core charge period. Duralast batteries have the capability to recharge faster than their Interstate counterparts. 

The reason for the short time recharging maybe because they have storage capacity is smaller and so charge faster, unlike the Interstate battery that has a large storage capacity and hence, charges slower.

Light indicators
