    5 Best Diehard Battery

    Factors to Consider While Buying

    We hope that we have made the process of buying the right DieHard battery for you simpler and convenient through our list.

    However, there are a couple of things you need to take note of prior to buying the battery.

    5 Best Diehard Battery

    Type of Battery

    The two main types of batteries used by car and watercraft enthusiasts are Lead Acid and AGM. The first type is the more common type of battery that is generally available on the market. Due to their popularity, they come in almost all sizes for various models. The second type, the AGM battery, is both newer in the market compared to its counterparts and lies on the expensive side.

    Lead Acid Battery: These batteries are inexpensive compared to AGM batteries, but on the other hand require more maintenance. Lead-acid batteries requires the addition of distilled water over the period of time. This electrolyte solution produces flammable gases when it evaporates. For the following reason, these batteries need to be well ventilated as even a small spark can cause irreversible damage to your precious motor vehicle. In terms of performance, they again fall behind the AGM battery. Therefore, considering the limitations, it is better to spend a little more money and get superior performance along with a longer maintenance-free battery life

    AGM Battery: They are widely regarded as maintenance-free batteries due to the fact that they don’t require frequent addition of water. Furthermore, a higher charging capacity and up to the mark performance ensures a smooth experience for car, RV, or watercraft owners. In addition, AGM batteries are able to hold charge for longer periods of time, so if you are not a frequent user of your motor vehicle, then this would be an even better choice.

    Battery Life

    One of the major concerns that haunt new battery buyers is it’s lifespan. You should never opt for a cheaper alternative as it would only offer a maximum life of 6 to 8 months. This would certainly provide a short-term solution, but in the long run it’s condition will start to deteriorate leaving you with a poor travelling experience.

    Most of the standard batteries from DieHard have a lifespan of over 2-3 years in most cases.

    Another point to remember is that you should never factor in battery life for better performance. A few years of consistent power with satisfactory performance is much better than just a few days of all-right performance.

    NOTE: Make Sure to get a Fresh Battery! Instead of buying a used battery, purchase a new one. Considering you don’t know the condition of the old battery and how long it will survive, it’s wise to spend a little more money on a new battery. Also, this way you are covered for another 2 years as most batteries have at least a 2-year warranty.


    Typically, all battery manufacturers with a high quality battery will provide their customer base with a 1 to 2 year warranty. But DieHard goes a step further. They offer up to 4-5 year replacement warranty, which is simply amazing.

    You should take all the necessary precautions to not violate this extremely pleasant side benefit that comes along with this brand. To ensure that your warranty remains intact, you should first read the violation guidebook thoroughly to understand all the things you need to avoid that can significantly affect your warranty. Even if you make silly mistakes, such as tampering with the warranty seal while installing the battery in your vehicle or damaging the exterior surface, you may unintentionally void your warranty.


    Among the various factors to choose from, performance should never be underestimated. Every battery owner expects a strong performance from their it, but if you lack the knowledge to tell a good battery from a bad one, you can end up wasting your money on a useless piece of junk. Firstly, every buyer needs to know what size and type of battery they need. After that, they should figure out what level of power is appropriate as per their needs. Note that with the purchase of a more powerful battery, the cost of its charger would also be on the expensive side. Our experts measure the performance of the battery considering the following factors.

    Ampere Hour (AH) Rating is the output of battery per hour. In simple words, the higher the AH rating of the battery, the less likely the vehicle is to run out of power. Therefore, make sure to buy a battery with a higher AH rating if you want an uninterrupted driving experience.

    The top pick on the list, DieHard 38188, has a 55 amp-hour (AH) rating which means that it would output 12 volts at the rate of 55 amperes per hour

    Cold Cranking Ampere (CCA) Rating can be defined as the power to start a vehicle at 0 degrees Fahrenheit. If you belong to or are planning to travel to a colder region, then this rating is a priority for selecting a battery for you.

    To better understand, CCA rating can be described as the number of amps a 12-volt battery can deliver at 0 degrees Fahrenheit for 30 seconds at a voltage of at least 7.2 volts of power.

    The higher the number of CCA ratings, the more amps the battery can deliver at a colder temperature, resulting in higher starting power for the battery.

    Reserve Capacity is, as the name implies, the capacity of your battery. That is, how long would your battery provide power if the charging system or alternator failed.

    To explain it technically, RC is the total number of minutes a completely charged battery will discharge 25 amps at a temperature of 80 degrees Fahrenheit while maintaining a voltage of 10.5 volts for a 12-volt battery.

    Generally, any average battery has an RC of 90-100 minutes, however, the batteries made by DieHard usually have a number higher than this. Sticking with DieHard batteries, opt for the variant where the reserve capacity is at least 120 minutes. Because in any emergency situation, a higher battery capacity could prove useful.

    Battery Size

    There are a variety of different-sized batteries available in the market to buy. To choose the right size of the battery, you must first measure the size of the compartment you want to install the battery in. You can either do this yourself and get the approximate measurements, or you can get the help of a professional mechanic. Ensure that the battery is of the accurate size and fits entirely in its compartment securely to avoid any trouble later.

    It should be noted that a larger battery packs more power compared to the smaller variants. So if your requirement is more power, then you should not go for the compact-sized battery models.


    The biggest reason DieHard has managed to make a name for itself is because of its maintenance-free battery models. Unlike their market competitors which require distilled water to be added weekly or bi-weekly to produce a electrolyte solution, DieHard does not require this. This is a huge blessing for people who remain busy and do not have much free time at their hands to perform this task on a regular basis.

    Considering all other scenarios as well, we can label batteries from DieHard as maintenance-free. However, you should be careful when removing or inserting the battery into the battery compartment, as incorrectly inserting or removing the battery will often result in a breach of warranty or even damage to the battery itself.


    Frequently Asked Questions

    Who sells die hard batteries now?
    Currently, Advance Auto Parts sells DieHard batteries. The brand already makes great products. But they have decided to be the official retailers of DieHard batteries. Previously, Sears was the only brand that did this.

    They still sell them. I suspect they will do so until the remaining stock is used up. It’s just a normal practice. So if you are looking for fresh inventory, then you should go to Advance Auto Parts.

    But even if you buy from Sears, you won’t have any problems. You will get the same warranty, and the durability of these batteries is also great. You won’t have to worry about getting dead or faulty batteries out of the box.

    Die Hard has really made stellar products. They have made sure that even products that have been on the shelf for some time are always ready to go.

    Do they have Walmart Sell Die Hard Batteries?
    No, they don’t. Although the Die Hard brand is on Walmart, they only sell products like battery chargers. As I said before, Die Hard only sells batteries through Sears or Advanced Auto Parts.

    There may be local dealers who resell the batteries, but it is rare to find sellers for Die Hard batteries. If someone claims to be an official dealer and doesn’t have the Sears or AAP name on them, you should report them.

    Also, they may be selling counterfeit products. You really don’t want to get into a mess like that. It’s always best to buy from known brands. Regardless, Walmart does not sell Die Hard batteries. You can check the brand’s official battery charging program there.

    How long do die hard batteries last?
    As I mentioned above, the brand offers a three-year warranty on its batteries. So naturally, you can assume that the battery will last that long. However, that is where you are wrong. A battery from Die Hard lasts about 4 to 6 years.

    The four-year mark is reached with rough use. If you use the battery carefully and don’t overuse it, then you can expect it to give excellent performance for six years.

    But, as you may have seen with the five products I listed earlier, there is a common problem of batteries failing on users. Although the chances of this happening are slim, it’s still possible.

    In this case, the battery can die at any time, from a few months to a year or even two. And the fact that you won’t even know if you’ve received a faulty product means that you’ll just have to use it to be safe. Thanks to the brand’s warranty, you won’t have to worry about that.

    Are Die Hard Gold Batteries AGM?
    It looks like you skipped the entire article and jumped straight to FAQ. Every single product I have listed above is from the Gold range of Die Hard. The reason they are so good is because they are AGM.

    If you are not familiar with this technology, then let me explain. An AGM battery uses thin fiberglass mats to hold the electrolyte. There is no free flowing acid, as with conventional batteries. This means that the battery cannot leak.

    It also doesn’t need water every few weeks. You can mount it in any position you want. All in all, an AGM battery is far superior to conventional batteries. I know I’ve strayed from the main question. But I feel obligated to explain it to you.

    After all, you need to know the difference to make sure you buy the right product for your vehicle. The Die Hard Gold product line is all AGM batteries. They are great and will keep you satisfied for a long time.

    What type of battery is a Diehard Gold Battery?
    Although it is called an AGM battery and uses an equivalent technology, it is a lead acid battery. But don’t get confused. I’m here to explain. In short, the AGM design is the latest version of the lead-acid battery.

    It offers a better CCA rating and better reserve capacity. You also get better durability and vibration resistance. So, let’s get into the details of what this means. Most vehicle batteries that are not electric use the lead acid design. That’s right. This is also true for AGM batteries.

    There is the use of electrolyte and lead. But in an AGM battery, the electrolyte does not flow freely, but is enclosed in thin sheets of fiberglass. The electrolyte is also in a gel format.

    So the battery is basically a lead acid battery, but it also works very differently. But it is far better than the wet cell or the free flowing type. Most importantly, an AGM battery doesn’t need water every few weeks.

    Is Die Hard Silver an AGM battery?
    Let’s talk about Die Hard Silver. This lineup was not mentioned anywhere in this article because the Gold one has surpassed it in every way. That doesn’t mean the lineup is poor quality or has issues.


    Most likely, you will need to replace your vehicle battery more than once during the life of your vehicle. This is because it gets old or depleted from constant charging and discharging. A dead battery can be a real problem, especially if you can’t find your jumper cables or have to wait for roadside assistance.
