Clore Automotive SOLAR ESA30 OBD-II Memory Saver Connector — Compact plug-and-play, preserves radio & ECU settings

When you disconnect a car battery for charging or replacement, modern vehicles can lose stored settings and learned parameters. The SOLAR ESA30 plugs into the OBD-II port and supplies a stable memory-preserving voltage to the vehicle’s systems so radios, security settings, and powertrain data remain intact. It’s a compact, single-purpose tool designed for technicians, DIYers, and shops that need a reliable way to protect vehicle memory during maintenance.

How does this connector protect vehicle memory during battery service?

The ESA30 provides a low-voltage feed through the OBD-II port, maintaining the vehicle’s electronic control units while the main battery is disconnected. That continuous supply prevents resets that would otherwise erase settings and learned values. It is intended for short-term use during battery removal, charging, or replacement.

• Plugs into standard OBD-II receptacles found on most post‑1996 vehicles
• Delivers stable voltage to preserve presets and ECU parameters
• Simple single-connector design for fast application

Will using the SOLAR ESA30 stop me from losing radio presets or security codes?

Yes—the device maintains the small but essential power that radio units, navigation systems, and immobilizers need to retain codes and presets. It helps avoid the inconvenience of reprogramming or resetting systems after battery work. However, always verify vehicle-specific requirements before service.

• Maintains radio presets, clock, and navigation memory
• Helps preserve alarm and immobilizer data where supported
• Reduces time spent reprogramming after battery replacement

Is the ESA30 easy to use for shop technicians and car owners?

Yes—the unit is plug-and-play: simply insert it into the vehicle’s OBD-II port while the battery is disconnected or being serviced. No additional wiring or setup is required, making it practical for quick in-shop use or mobile service calls. Its compact form makes storage and transport straightforward.

• No tools or installation required—plug into the OBD-II port
• Compact, durable housing for workshop use
• Ideal for quick battery swaps and diagnostic sessions

Are there vehicle compatibility limits or precautions?

The SOLAR ESA30 fits standard OBD-II ports found on most vehicles built since the mid-1990s, but always check the vehicle manufacturer’s service guidance. Some models may require manufacturer-specific memory savers or procedures. Avoid leaving the connector in place longer than recommended by service instructions.

• Compatible with most OBD-II equipped vehicles; verify fit before use
• Follow vehicle-specific service manuals for safe use duration
• Not a substitute for manufacturer-prescribed maintenance procedures

Who is this for: The Clore Automotive SOLAR ESA30 is for mechanics, mobile technicians, and informed DIYers who perform battery maintenance and want to prevent loss of vehicle settings. It’s also useful for service centers that need a fast, repeatable solution to protect electronic memory during charging, testing, and battery replacement tasks.
