Selecting the right battery for your Honda Prelude III (1987-1991) is crucial for ensuring reliable starts and smooth operation, especially given the specific requirements of these models. The third generation of the Prelude is well-regarded for its sporty character and innovative engineering for its time, but like any classic vehicle, it comes with its unique set of needs when it comes to electrical power. Understanding the requirements for your car’s battery will help you avoid common pitfalls, extend the life of your battery, and keep your Prelude running at its best.
For all variants of the Honda Prelude III from this period, specifically the 2.0, 2.0 EX, and 2.0 i EX 16V models, the recommended battery should be a conventional lead-acid battery (also known as a flooded or SLI battery—starting, lighting, ignition). This type remains the standard for vehicles without Start-Stop systems, as is the case with the Prelude III. These batteries are well-suited to the relatively simple electrical systems of 1980s and early 1990s cars, providing reliable cranking power and steady performance under a variety of conditions.
In terms of specifications, the capacity of the battery should fall within the range of 70 to 75 Ah (ampere-hours). This ensures that the battery can store enough energy to power the vehicle’s starter, lights, and any accessories you might use without being oversized or unnecessarily heavy. The cold cranking amperage (CCA)—a measure of how much current the battery can deliver in cold conditions—should be between 540 and 630 A. This is especially important in colder climates or if the vehicle is stored outdoors, as lower temperatures can make engines harder to start and reduce battery efficiency.
One of the most critical aspects to consider is the physical configuration of the battery, particularly the terminal layout and the type of mounting. The Honda Prelude III may require a battery with the positive terminal on the left side. This is not as common as the right-hand configuration, so it is essential to double-check before purchasing. Using a battery with the wrong terminal layout can make installation difficult or even impossible without modifying the cables, which is not recommended. Additionally, the mounting type for these cars is typically B01 or B9, rather than the more common B13. This means that you’ll need to look for batteries that match this specification to ensure a secure fit in the battery tray. An improperly secured battery can lead to electrical issues or even physical damage to the battery or the vehicle.
There are a number of suitable battery models available on the market that meet these requirements. Examples include the Bosch S40 27, Exide EA755, Exide EB705, and Varta E24. These models are just examples of compatible batteries; there are other brands and variants that can also fit if they match the required specifications. When shopping, always check the manufacturer’s datasheets for terminal layout, mounting type, dimensions, and cold cranking amperage to be sure of compatibility.
One interesting aspect of classic cars like the Prelude III is that battery requirements can sometimes be overlooked in favor of more glamorous upgrades. Yet, the battery is at the heart of every reliable start and every enjoyable drive. Owners who invest in the correct battery not only avoid inconvenience but also help preserve the vehicle’s electrical components, as using an ill-fitting or underpowered battery can put unnecessary strain on the alternator and starter motor.
In summary, when choosing a battery for your Honda Prelude III (1987-1991), focus on a lead-acid battery with 70-75 Ah capacity, 540-630 A cold cranking amperage, left-side positive terminal, and B01 or B9 mounting. Example models like Bosch S40 27, Exide EA755, Exide EB705, and Varta E24 provide a good starting point for your search, but always confirm the exact specifications before purchasing. With the right battery in place, your Prelude will be well-equipped for years of classic motoring enjoyment.
Honda Prelude in version III was produced in the years 1987 – 1991. Below we present the specifications of batteries suitable for specific engines.
Basic parameters of batteries suitable for Honda Prelude (1987-1991):
| Layout | Terminal types | Base hold-down |
|---|---|---|
| 1 – positive on the left side | 1 | B9 |
| 1 – positive on the left side | 1 | B01 |
Honda Prelude III – petrol engines:
- 2.0
- 2.0 EX
- 2.0 i EX 16V
| Model | Capacity and CCA | Dimensions (LxWxH) | Price |
|---|---|---|---|
| Bosch S4 S40 27 | 70 Ah 630 A | 261x175x220 mm | More |
| Exide Excell EB705 | 70 Ah 540 A | 270x173x222 mm | More |
| Exide Premium EA755 | 75 Ah 630 A | 270x173x222 mm | More |
| Varta Blue Dynamic E24 | 70 Ah 630 A | 261x175x220 mm | More |
For the Honda Prelude III produced between 1987 and 1991, equipped with the 2.0, 2.0 EX, and 2.0 i EX 16V petrol engines (all without Start-Stop systems), several types of car batteries are suitable. The recommended batteries for these engines generally fall within the D26 case size standard, which typically measures approximately 260x173x225 mm. The batteries listed, such as the Exide Premium EA755, Exide Excell EB705, Bosch S4 S40 27, and Varta Blue Dynamic E24, have very similar dimensions, with lengths ranging from 261 mm to 270 mm, widths of 173-175 mm, and heights of 220-225 mm. This means they are all compatible in terms of physical fit within the engine bay, as they conform to the D26 battery box size commonly used in Japanese cars of this era.
A key difference between these batteries lies in their capacity and cold cranking amps (CCA). For example, the Exide Premium EA755 offers a higher capacity at 75 Ah and a CCA of 630 A, which can provide more reliable starting power, especially in colder climates or for vehicles with more electrical equipment. The others, such as the Exide Excell EB705, Bosch S4 S40 27, and Varta Blue Dynamic E24, offer a capacity of 70 Ah, with cold cranking currents ranging from 540 A to 630 A. While the difference in capacity may not be critical for all users, those who drive in harsh conditions or use additional electrical accessories may benefit from the higher rated battery.
Another important aspect is the battery mounting and terminal configuration. All listed batteries have the same terminal layout, and use standard terminal types, which matches the typical requirements for the Honda Prelude III. However, there could be slight differences in the mounting base code (B9 for Exide, B01 for Bosch and Varta). Both B9 and B01 refer to standard base hold-downs for Japanese vehicles, and in most cases, either will fit, but it is always best to check your current battery’s mounting system to ensure compatibility. Since Honda could have installed different batteries depending on the market or specific engine variant, it is recommended to compare the dimensions, terminal orientation, and hold-down type of your old battery with the new one before purchasing. This will help ensure a proper and secure fit, maximizing both performance and safety.
