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.

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 that’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 I’ve bought for cars, trucks & boats over the past 30 years of being a professional auto & boat mechanic.

Anazon website indicates this battery will NOT fit a 2022 Maserati Levante, but that is incorrect. This is the exact same replacement battery sold by my local Maserati service center. I was able to remove the old battery and install this new one in about 15 minutes, saving over $280 from the Maserati quoted replacement cost.

The battery worked great for 2 months, then started draining overnight. I searched for a component draining my battery but amp draw was minimal. Installed a new battery because interstate battery warranties are submitted through third party mechanics that won’t honor the warranty if they did not sell it. Battery had terminals that were not standard size, causing a looser fit on the clamps. I would not recommend this battery to anyone.

batteries are so expensive might as go with a premium brand. I think this brand is far better than oem. my vehicle sat for 6 months and the oem battery had total died and would not take a charge. car batteries used to be 100 dollars but were very poor quality. modern battery technology is amazing but expect to pay 300.00. i made the mistake of not starting my vehicle and driving for an hour to charge the battery.

Replaced the 4 year old, dying battery, in my 2020 Silverado with this baby. The difference a quality battery makes is amazing, you can hear it whenever the starter turns over for the first time! Interstate batteries have always done well for me in the past and have lasted long beyond their expext lifetime. Thanks for a great battery at a great price, Amazon!

Thought I bought a good battery from a trusted US based company. Not so! Battery lasted a few months now won’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! This is in addition to the previous review. I brought the battery to a local Interstate dealer. They tested the battery and it failed the load test. I turned the old battery over to them. I asked if they could replace the battery under the 3 year warrantee since battery was less than a year old. They said they would not get credit for it because it came under a different distributor. All this crap from Interstate saying you can turn a failed battery purchased online to a local dealer is totally false. I had to buy another battery from them.I submitted a claim to the Dept of Consumer Protection in my State. They contacted Interstate and presented them with my paid invoiced, the entire string of email communications, photos of the battery and a copy of the 3 year warrantee. Interstate disputed everything so I am out. It is up to you who you want to do business with but fair warning to all regarding Interstate batteries purchased through Amazon. BTW, the new battery purchased through the local dealer was fifty dollars less!
