How Do You Replace A Group 78 Battery In A Car

Replacing a Group 78 battery in your car is an easy task on most vehicles. You only need a few simple tools like a crescent wrench or socket set, a wire brush, and a few shop rags. Before you begin, make sure that your engine is off and that your emergency brake is set. Lift the hood and use the holder to keep it up. Now, you are ready to proceed.

What Is The Best 78 Group Battery

A Group 78 battery refers to a battery with certain size dimensions. A Group 78 and Group 34 Battery are identical in size, but a Group 78 battery has terminal posts on the side. There are some cars where the hood does not have enough height to accommodate top post batteries. In these cases, a Group 78 battery solves the problem. In some cars, you can use either a Group 34 or Group 78 battery without any problems.

Group 34 and Group 78 batteries have similar specifications in terms of cold-cranking amps, amp-hours, reserve capacity, and lifespan. Some Group 78 batteries use thick plate technology and are suitable for deep-cycle use and cars that use heavy electronics. Other Group 78 batteries use thin-plate technology and are better as an SLI battery. Some Group 78 batteries use a combination of these technologies and are appropriate for deep-cycle and starting applications. Groups 78 batteries average between 750 and 800 cold-cranking amps. They have an average reserve capacity of 110 to 134 minutes.

What Are Agm Batteries

AGM batteries are different from typical batteries in that glass mats hold the electrolyte that is used as opposed to freely flooding plates that are in conventional automotive batteries. Because of this, AGM batteries like the Duracell AGM Automotive Battery are considered to be maintenance-free. They do not require watering service from time to time and that appeals to many, especially if the AGM battery is tucked away.

How To Get 24 Volts From 12v Of A 78 Battery Group

If you need 24 Volts, you can connect two group 78 batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries. If one 12V lead-acid battery is connected to another 12V lead-acid battery, you have 24V total power output. Each battery must be fully charged and completely isolated from the other before connecting them in series, or there will be damage to at least one of them.

What Is The Difference Between A Group 34 Group 75 And Group 78 Battery

Sometimes you will see a Group 34 and Group 78 battery listed together as 34/78 or 34-78. This is because both of them have identical dimensions. A Group 75 battery has the same width and height as a Group 34 and Group 78 battery, but they have a slightly shorter length. A Group 75 Battery is 9.1 x 7.1 x 7.3 inches. Group 75 and 78 batteries have terminal posts on the side, so this wont add to the width dimensions.

Many people question whether you can substitute a Group 34, 78, and 75 Battery. This is a more complicated question regarding these battery groups than with other top-post-only comparisons. Group 78 and 75 batteries are used when the engine compartment is short in height and the hood comes close to the engine components. In this case, a top post battery, such as a Group 34, might not allow the hood to close. That is the main reason for using a Group 78 or 75 battery. If you decide to substitute a Group 78 or 75 battery for a Group 34 battery, you must make certain that there is nothing close to the sides of the battery that might get in the way of accommodating the side posts.

Increasing A Capacity Of 78 Batteries With A Parallel Connection

If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group 78 batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities. If you have two 12V lead-acid batteries with 60 Ah capacity and you connect them in parallel, you’ll get 12 Volts with 120 Ah.
