If a user is searching for a BCI group battery to install because of the side post or terminal purpose, a BCI group 78 battery is a perfect choice, especially, driving in a cold and stormy environment. Although it is common that a vehicle may accept a multipurpose battery size, for instance, a BCI 34/78 battery is compatible with a car that accepts a BCI group 78 battery.
All about is the height clearance because most of the side post terminal 78 batteries request a 10” or less than 10” hood to cover it properly, neither the hood may not close nor the appropriate matching is possible.
For removing all your confusion between top post, side post, and dual-purpose to select for your private or heavy-duty vehicle, we have enlisted your queries in FAQs and the buyer’s guide section. We hope the prospective users love to get out of the puzzle conditions, a plus point of top-picks of group 78 battery is a working and driving breeze.
What Is a Group 78 Battery?
A BCI group 78 battery is a common need for vehicles, consisting of terminals on the battery side. Similar to other identical battery sizes, this one is superior in its own characteristics with specific optimization. Group 78 batteries of different brands often fit with terminal optimization instead of 34 batteries, yet the terminal height suitability is a barrier.
Although a 78 battery splits in terms of dimensions and features from a 34 battery, their Spiralcell often provides better electrolyte and lead components which allows contact fast and smoothly at any time. Even quite an initial burst for starting and a faster charge to carry it anywhere you need.
Are Group 78 Batteries Safe to Use in Sensitive Electronic Equipment
Group 78 batteries are safe to use in sensitive electronic equipment, as long as the battery is the right size and type for the device. Always check the manufacturer’s specifications before using any battery in sensitive equipment.
Group 78 Batteries – Dimensions and Features
Such a dual-purpose battery of 78 sizes is often good to go for the “Stop and Go” term and automotive applications. Since the batteries require huge currents and are to be charged quickly for instant applications, you have to choose a group 78 battery for tougher and more durable jobs to accomplish.
In terms of dimensions, rather than group 31 batteries, a group 78 battery is available mid-size and shaped for holding lead-acid. Such lead-acid battery form is very practical, not only to keep up with Absorbent Glass Mat (AGM) batteries but also to provide much more charging capacity than general batteries for cars or heavy-duty vehicles like trucks and caterpillars. Sealed with either SLA or AGM prolongs the battery life.
Types of 78 group batteries may vary, as well as wet/flooded, gel-cell, LiFePO4, or Lithium Iron Phosphate. However, the battery’s physical dimensions are nothing unusual as we have mentioned before, and it has more interchangeability power to get compatible with 34, 31, and sometimes 24 battery groups.
The prior and standard dimension of group 78 batteries is:
L x W x H: 10.25 x 7.0625 x 7.6875 inches (26 x 17.9 x 19.6 cm)
However, featuring 3/8″ terminal posts makes it different from the group of batteries in the common crowd, indicating from the front side both positive and negative respectively to the left and to the right. But don’t get overwhelmed by the label of ’34/78′, as if both 34 and 78 are similar by featuring top SAE terminals. Also, in order to split the common size of the battery compartment, sometimes such a group of batteries is available with labels of DT or Dual Terminals.
FAQs
What Cars Take Group 78 Battery?
This is a battery group for side post accepted vehicles and terminals either in positive or negative in respectively negative or positive. This number is a measurement for taking space inside the transport to start its motor.
A vehicle of each battery group requires a specific amount of amperage to let you drive smoothly, in fact, the cold weather adjustment is not a barrier indeed. So, users should be aware of cold-cranking amps. Therefore, we have found GM, Chrysler, and Dodge which accept group 78 batteries at ease.
What is the Difference Between Group 65, Group 75/78, Group 24/24F, Group 35, and H-Series batteries?
Each of the group’s identical dimensions means to separate them in task accomplishment and acceptance by different car brands. For example, groups 75, 78, and 34 have almost similar dimensions, 9.1 x 7.1 x 7.3 inches. Also, all of the terminal construction is on the side post.
In terms of top-post comparisons, the battery compartment does not come close to the hood and is easy to adjust and get covered, for instance, a group 65 battery.

How Long Do Group 78 Batteries Last?
Labels that are attached to the battery part indicate how long a battery you can apply properly. Whether a battery features more than 24 months or others may be below the range. But AGM or absorbent glass mat technology constructed batteries support more unlike LED-Acid leaves the chance of overflooding.
Other factors, for instance, design with spillproof tech, continuous contact in between electrolyte and lead plates of the battery resist power-draining while the battery is in storage mode, and stabilizes the power in itself as well.

Last yet not least group 78 battery as if another powerful model from Odyssey. This one is another 12 V battery, yet an excellent choice if you are determined to have a starting and deep-cycle feature altogether at once. However, we found it very much reliable in terms of driving in cold weather without any noise and vibration creation.
Its poor self-discharging discouraged our minds from purchasing it. However, its tight manufacturing control and experiencing review of good consistency made our mind to install it in private vehicles.
Starting vs Dual-purpose
Users differentiate between starting and dual-purpose 78 batteries in terms of facilities in applications. However, a dual purpose is better than a conventional flooded or starting battery sometimes. One can install a deep cycle battery instead of a starting battery. But how?
Well, a deep cycle battery construction has entirely been processed with heavy, thick, and rigid plates. In the case of starting model battery construction, no advanced design to become potential for multiple discharge/recharge cycles means the recharge system runs by the alternator.
In short, a starting battery optimizes mostly the normal engines though it delivers in a shorter time an applicable huge burst of power in its powerhouse. Therefore, it is obvious that a deep cycle battery user can install a heavy or private vehicle to start your mother by an instant pinch. One rule of thumb is the motor with 2 or 3 systems you should separate from the engine battery as if from the in-house batteries.
Deep cycle or dual-purpose batteries are far better complicated yet powerful with a heavy powerhouse for supporting your vehicle engine for longer, even, however, the climate you are driving on the road.
Such a steady amount lets the engine self-recharge and protects it from heavy leakage to avoid any accidents. Moreover, such a dual-purpose model is well-suited to increase a wide range of electronics and plug-in accessories to drive the motor as well. However, as per our experience, users can use a similar battery for cranking and trolling.
34/78 vs 78 Batteries
We have mentioned which cases and how you can utilize a dual-purpose battery or a starting model. For mild-to-moderate amp draw services, a dual-purpose battery is standard to operate. However, we have experienced a typical model with more than a group 78 battery, group 34/78 battery.
34 number recommends a battery of certain dimensions with both top terminals, for instance, positive and negative. On the other hand, 78 battery group refers to side terminals engaged in a construction capacity. However, 2 different physical dimensions, at least relative to each of their size apart from similar terminals. But one thing should users remember until the height issue becomes cleared with top terminals, neither group 34 nor group 34/78 battery installation is possible.
Wrap Up
A common side terminal battery that your vehicle needs is the 78 number referred battery group. An identical size you can find anywhere to empower your vehicle motor. As we have picked out some excellent group 78 batteries which are rather reliable than other sources and hopefully such excellent picks will let you verify the engine circumstances in any weather.
In particular, if you need better maintenance and charging fast, get optimized with the ACDelco 78AGM BCI Group 78 Battery.
