Frequently asked questions

The 800 Cold Cranking Amps (CCA) rating indicates the battery's ability to start an engine in cold temperatures. Specifically, it measures the battery's ability to deliver a certain amount of current at 0ยฐF for 30 seconds without falling below a specified voltage. This high CCA value means the battery is well-suited for starting vehicles in cold climates.

Yes, the Interstate Automotive Battery is versatile and can be used in a variety of vehicles including SUVs, sedans, trucks, and vans. Its design and power output make it suitable for a wide range of automotive applications.

AGM (Absorbed Glass Mat) refers to a type of battery design where the electrolyte is absorbed into glass mats, as opposed to freely flowing within the cell. Pure lead AGM batteries, like this one, are known for their higher performance, durability, and longer life compared to standard lead-acid batteries. They are more resistant to corrosion, can charge faster, and are less susceptible to sulfation.

The Interstate MTZ-34 Battery is designed to fit in a variety of vehicle models comfortably, matching the physical dimensions and terminal positions of Group 34 batteries. While installation is straightforward for those with basic mechanical skills, consulting the vehicle's manual for specific instructions or seeking professional installation is advised to ensure safe and correct fitting.

๐Ÿš€ Abunda's Overview

This is our summary and key points to consider based on customer reviews.

The reviews for this battery show a wide range of experiences, emphasizing its high performance, reliability, and outstanding power output, with particular praise for its ability to exceed expectations in power tests. However, issues with compatibility and the challenges of warranty service highlight some concerns. Most negative reviews are focused on fitment issues rather than the battery's performance itself.

Pros

  • ๐Ÿ”‹ Strongest and most reliable battery, according to some users
  • โšก Far exceeds expectations in power and cranking capabilities
  • ๐Ÿ›ก๏ธ Carries a four-year warranty, showcasing confidence in longevity
  • ๐Ÿš— Excellent performance for specific vehicle applications mentioned

Cons

  • ๐Ÿ’ธ Very expensive, making it a significant investment
  • ๐Ÿ”„ Compatibility issues with certain vehicle models leading to fitment problems
  • ๐Ÿšš Some challenges noted with warranty service and returns
  • ๐Ÿ“ฆ Packaging for shipping could be improved for better protection

Should I Buy It?

If the battery fits your vehicle model and the price is within your budget, its high performance, reliability, and exceptional power make it a solid investment. However, double-check compatibility to avoid the fitment issues some reviewers experienced. The drawbacks seem limited to specific cases rather than general product quality.

Awesome batteries for my 2011 Duramax. The price was way cheaper than anywhere else, they arrived quickly, very well packaged, and work better than expected. Definitely worth the money.

    • Interstate The best non-lithium batteries you can buy
Style: Group Size 49
Shipped very well & fast in a box with expandable foam to secure it snuggly in place. I highly recommend buying a battery this way every time I need one. I should also mention this was a current battery with a full charge (I checked it) not something old thatโ€™s been sitting on a shelf somewhere in a retail store not properly rotated to keep the dates rotating in order. Buy with Confidence! Interstate has always been the best quality, strongest, longest lasting batteries out of all the batteries Iโ€™ve bought for cars, trucks & boats over the past 30 years of being a professional auto & boat mechanic. ... show more

    • Junk
Style: Group Size 65 (MTX)
Purchased to replace 5 year old batteries on my Diesel Truck. They came in charged. Started truck first try. I did not start the truck that is garage kept for about 4 weeks. Completely dead and will not take a charge. I purchased two batteries at this time. Unhooked each battery and tried to slow charge each one individually. Totally dead. Will not charge. I will attempt to take to the Interstate Battery company next town over ( 30 MIles ) hopefully they will honor the warranty and give me a good set of batteries. My suggestion is to deal local. thought I would save a few dollars. Will spend more in time and effort now than i saved. ANd I did not mention there where several date stickers on each battery, like they changed to a newer sticker when shipped. ... show more

    • High quality product so far.

Works as should. It took longer to cut it out of the foam packaging than it did to install it.

    • Not good.
Style: Group Size 48
Thought I bought a good battery from a trusted US based company. Not so! Battery lasted a few months now wonโ€™t hold a charge. Found a sticker on top of the battery that says Made in China! WTF? Interstate says I need a certificate showing the battery is dead. That means taking it to a dealer and spending more money for a test. Used to love Interstate batteries. Not anymore! ... show more

Reassuringly heavy and on time delivery. These are AGM not Standard. Charge meter showing the proper 98% full now. I did a lot of research on these, with more satisfied customers than any other. Looks like a quality build.
