Things to Consider When Buying Diehard Batteries

Which Type Battery You Want

There are two types of battery for the vehicle like cars, watercraft, etc. One type is Lead acid battery that is the general type, and another one is AGM (Absorbed Glass Mat).

They function differently and also work differently in the certain situation. Here I am going to write about both of their application.

So make sure you get right types battery that surely matches your application.

Lead Acid:

These type batteries are most commonly used. It’s used electrolyte water solution that is the main source of power.

Its removable cape allows you to change water solution and maintain it that modern battery doesn’t require.

From price prospective, you find the lead-acid battery is significantly lower priced than AGM. But the performance is not as good as AGM.

It hardly tolerates deep discharging and won’t able to hold charge long time. Overall this type of battery is not recommended for an automotive vehicle.

AGM (Absorbed Glass Mat)

This modern system battery required less maintenance and have a great charging capacity. It’s becoming more common and standard equipment among car, truck, watercraft, etc.

It can hold the charge for a long time and easily tolerate deep discharging. If you don’t use your vehicle for a long time, then this type of battery would be a great option for you.

Even if the battery drained accident you can’t recover its performance. So I recommend it to you.

Choose the Right Size

Before buying any battery, you have to find out what size will fit on your vehicle. If you buy a wrong sized one and try to install forcedly, then it would be violet you warranty guideline.

Even if you don’t violate warranty rules, but still it’s time-consuming to return the battery and replace another one.

Now if you are not sure about your battery sizes then contact your mechanic to ensure buying right size one.

Get a Fresh Battery

It’s always a bad idea to get a cheap old battery for your vehicle.  Even don’t buy a stored battery that’s been six months old.

You may know that battery performance and strength gets lower over time. So every time you buy a battery make sure to get one that is not constructed over six months old.

Now, how you find the time of your battery construction? The maximum time you get a shipping code on your battery case like A8 or B7.

Here A8 means it constructed on January 2018 (here A means January and eight means 2018). For B7 the construction date is February 2017 (here B means February and seven means 2017).

So that’s all you have to know to get a fresh diehard battery.

Minimum Warranty You Need

Warranty is a questionable thing for diehard battery. It’s an important consideration at every time you buy a new battery for your car, truck or watercraft.

A 24-month free replacement warranty is the minimum requirement for any battery that we prefer. You also should go for a prorated warranty that at least 84 month time period.

Read the warranty violation guideline properly to avoid any kind of confliction. Be careful about battery installation and low water level that can violet your warranty.

Now diehard is the best battery brand in the market. So if you choose the right one and place it properly in your vehicle, I think you never need to go through the replacement process.

Battery Life

It is a pain to change your vehicle battery every six months. To avoid any type of battery confliction in your journey, you need a long life battery for your vehicle.

Standard battery life is 2-3 years. So I recommended going for a battery that has 2-3 year free replaceable warranty.

That means the company is confident in their product and can last at least 2-3 years which is great. Now diehard is a reputable brand and if they offer this type of warranty then go for it.

Performance (RC)

RC is the short form of your battery reserve capacity. This is the indicator of your battery performance that measures how much time your battery can supply power if the charging system fails.

So it’s a very important thing that must be considered when buying a new diehard car battery. A one and half hour (1 1/2) reserve capacity (RC) is standard for any type of battery.

Now for diehard batteries, I would suggest for going at least 2 hours RC that worth your money.

Things to consider before buying

Buying batteries online may be a little bit risky but make sure you check reviews before investing. You can check out Exide edge AGM review on Amazon to consider as your new battery. It has most of the features that a battery should have.

Power of battery:

A battery is for giving fire to the car. As this is its basic job, if you ignore this main part and get attracted to other features then you will be making trouble for you and your vehicle. First and foremost you have to check out the power of a battery.

If it is enough to power your car then keep it in your wish list. You can go fancy with it by selecting a more powerful battery as well. Powerful batteries need more powerful chargers to keep that in mind as well. If your vehicle is for simpler use, then it is not necessary to go overboard.

Check out Warranty:

Then, check guarantees of all the available brands in the market. The more guarantees it provides the better it is. Replacement guarantees with cost-free options are better. You can compare companies with each other’s benefits other than warranties as well. Longest warranties are better as some batteries lose their ability in six months or so.

Battery size:                  

Before buying a battery you need to check the width, height, and length of it. The right side of the battery is best for a car as it prevents from damage caused by vibration. You may not be able to do it yourself. Ask a mechanic to help measure for correct sizes. Then your battery will fit into the car and be secured.

Battery manufactures date:

Manufacture date indicates the freshness of the battery. The code on the battery that has a date, month and year indicate how fresh the battery is. Never buy a battery that is more than six months old. Batteries lose their ability by the passage of time which you do not want to face by buying an old battery.

Reserve capacity:

Reserve capacity means how much time the battery can go without the help of the engine and before discharge. Meanwhile, Reserve capacity is very important in tough situations. Your battery with better reserve capacity will be able to handle tough situations like the noncompliant engine, alternator failure or accidentally leaving lights on. It also proves how powerful the battery is.

Cold cranking amps (CCA):

CCA is known as the power requirement of the battery to start. Cranking amp is 32-degree energy required for the engine to start. But cold cranking energy is when the engine can be started in zero degree temperature. If you are living in a cold climate this will help you go through rough weather. Batteries with CCA will work without disturbance in hot or cold both temperatures.

Frequently Ask Question:          

What is the standard RC (reserve capacity)?

80 is the standard RC. But maximum top rated battery brand provides RC more than 100 as they are used in the vehicle.

For the diehard brand maximum of their battery comes with a 120 RC. Some of them even come with more number. 

How Long Does Diehard Battery Last?

Diehard always produces the long-lasting battery. At the early time, their battery sometimes lasted the same to car life. Now the modern car has a well-extended life, but still, they have an excellent performance.

Diehard generally gives a three-year free replaceable warranty. So you can say that the battery can last at least three years or even more on average.  

Is Diehard battery any good?

Yes. Diehard is the best brand that I found in the battery industries. They provide a long lasting battery that makes them popular.

I find only one complaint against them is the warranty. Now the warranty depends on many things. If you buy from wrong place or violate their warranty rules, then it’s not their fault.

How long is the warranty on a sears diehard battery?

Sears mainly provide three type battery Diehard, Diehard gold and Diehard Platinum. They have different power and warranty.

Normal Diehard battery provides an 18-month warranty. Diehard gold has three years, and platinum has four years warranty.

Conclusion:

So this is the end of this best diehard battery review. You don’t want to change your vehicle battery in every six-month diehard would be a good option for.You also check very special Optima battery for your Car.

They are enough durable and long lasting that keep you safe from facing any unusual situation. Hope this diehard lithium-ion battery jump starter reviews will help you to choose your desired one.
