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 0°F 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.

  • Easy install - worked with Odyssey battery holder
Size: Group Size 34R
I bought this 34R battery to replace an Odyssey 34R battery. I was worried that the Interstate battery wouldn’t fit correctly in the Odyssey battery holder, but it fit perfectly. In fact with both batteries side by side it looks like they are from the same manufacturer. Every indentation and crease is identical when comparing both batteries. The only difference I could see are the colors and branding. Both are probably manufactured by Johnson Controls. ... show more

  • Just a Couple of Things.
Size: Group Size 34R
A bit pricey but after asking around it seems to be the battery you want to have under your hood. I had no battery in my 2018 4Runner for about 30 minutes while making the switch and the only thing that needed to be reset was the cabin clock. No "Memory Saver" was used. Also, Interstate says the battery fits a 2018 4Runner but Amazon says that it doesn't fit a 2018 4Runner. Well, I found that the Interstate battery was just a bit shorter than the stock battery I was replacing. As a result I couldn't tighten down on the battery retaining screws enough to hold the battery securely in place. I'm sure that there are 1000 ways to take up the slack but what I did was purchase a piece of black hose and using a box cutter I cut two "U" shaped pieces each about five inches long. I positioned them over the front and rear edge of the battery that are under the battery clamp and tighten down on bolts. It worked perfectly. ... show more

Excellent AGM Battery! It costs more than a lead acid battery, but in this case you get what you pay for. It won’t let you down.

  • It fits sort of
Size: Group Size 34
I have a 2005 Honda Odysee van and though they claim it is compatible it did not fit perfectly. The positive cable was difficult to get on because it needs to be about an inch longer but I made it work. I also feel that this battery is way to costly, hope it lasts as long as they claim.
