The Del Sol from 1995 uses a Group 51R, 12-volt automotive battery as original equipment.
In practice, the Del Sol's engine bay is configured to accept a compact, standard 12V lead-acid battery, and the Group 51R fits neatly with the terminal positions aligned for the car's wiring harness. Some replacement options may list Group 51 or Group 35 as alternatives, but the factory fit for most US-spec 1995 Del Sols is Group 51R. Always verify the exact group size by checking the label on the battery you remove or the owner's/parts manual for your VIN.
Understanding Battery Group Sizes
Battery group size is a standardized code that defines the battery's overall dimensions, terminal layout, and fit in the vehicle. For Hondas of this era, Group 51R designates a compact, 12V battery with a positive placement and a slightly different terminal configuration versus non-R versions, which can affect compatibility with mounting trays and cable routing.
What the "51R" designation means
The number "51" points to the battery’s approximate size class, while "R" indicates the reversed polarity standard used on some models. In many North American Del Sols, Group 51R batteries are the correct match, providing enough cold-cranking amps (CCA) for typical start-up and electrical loads.
How to verify and replace safely
To ensure you get the right fit, check the existing battery's label for the group size (e.g., 51R), measure the battery tray, or consult the owner's manual or a parts catalog using your VIN. When replacing, match the group size, CCA rating suitable for your climate, terminal orientation, and the battery's footprint with the Del Sol's battery tray and hold-down hardware.
Summary
For most 1995 Honda Del Sols, the correct replacement battery size is Group 51R. This compact, 12-volt lead-acid battery fits the engine bay without modification and provides the appropriate cranking power for standard electrical loads. Always confirm the exact group size from the vehicle's documentation or the current battery label before purchasing.
