About Interstate Batteries

One common complaint I have heard about Interstate batteries is their higher pricing compared to the rivals.

But using their products and having no worries for 48 months is worth investing the additional money.

Also, intelligent battery design and better component quality are there to ensure that the batteries don’t self-discharge quickly.

According to the company history, Interstate was owned by Brookfield and Exide Technologies. And, Johnson Controls is the manufacturer.

In their product line, you will find non-AGM, marine, AGM, MTP, MT, RV, and Powersport vehicle batteries.

According to the users, Interstate batteries are best suited for some on-road vehicles, Powersport, and small personal automobiles. Also, they are good in backup systems and renewable applications for reliable performance. On the other hand, Deka is considered widely in marine and renewable use cases for its performance and durable performance.


As both brands’ manufacturing quality is almost similar, you have to consider warranty more than other factors. Here, I like Interstate for its 48-months warranty period.
