BatteryMINDer® SCC1224-AA-S2 12V/24V Aviation Solar Charger-Maintainer-Desulfator For Gill Batteries
Features & Benefits:
• Guaranteed to never overcharge, regardless of how long connected.
• Solar battery charger maximizes battery life and capacity and reconditions weak batteries.
• Maintains up to 2 batteries at a time.
• Short circuit, spark, and polarity protection.
• The internal program adjusts its output several times a second, based on this reading, to quickly and correctly charge your battery.

QUESTIONS & ANSWERS
The battery should be in “good” condition, meaning no shorted cells and a rested voltage of at least 8.5V for a 12V battery or 17V for a 24V battery. Severely damaged or internally shorted batteries will not benefit from solar desulfation. Verifying open-circuit voltage before installation ensures the solar charger can properly maintain and restore the battery.
The controller should be installed in the same general temperature environment as the battery to ensure accurate temperature compensation. Because the charging voltage is automatically adjusted based on ambient temperature, variations in environmental conditions can cause improper voltage regulation. The mounting location also allows easy viewing of the LED status indicators while protecting the unit from direct rainfall and intense sunlight.
The SCC1224-AA-S2 lowers the charging voltage in hot conditions to prevent excessive gassing and raises it in cold conditions to maintain a full charge. This automatic adjustment is especially important for aircraft stored in unheated hangars or exposed to seasonal temperature swings. Proper voltage control reduces sulfation risk and helps extend Gill battery service life.
The controller must not be used with solar panels with a total output exceeding 20 watts. Using a higher-wattage panel can damage the controller and void the warranty. Matching the correct 20-watt solar panel ensures safe, regulated charging performance.
The built-in BCI allows users to quickly assess the battery state of charge by pressing the “PUSH” test area. Three illuminated LEDs indicate a fully charged battery, while fewer LEDs signal fair or poor condition. This quick visual diagnostic reduces the need for separate voltage meters during routine checks.
According to the testing chart, a fully charged 12V battery reads approximately 12.5 to 13.2 volts, while a 24V battery reads 25.0 to 26.4 volts. Lower readings indicate fair or poor condition, potentially requiring additional charging or desulfation. Monitoring the resting voltage helps determine whether the solar maintainer is effectively maintaining the battery.
Yes, the SCC1224-AA-S2 can maintain two parallel-connected batteries, provided they are the same type and capacity and are in good condition. However, total output is limited by the available solar energy from the panel. Matching battery size and condition ensures balanced maintenance charging.
When solar input drops below a usable threshold, the controller temporarily shuts down to prevent battery discharge. Once sufficient sunlight returns, the system automatically resumes charging and desulfation. This self-regulating feature protects the battery during fluctuating solar conditions.
The solar panel should be covered during wiring to prevent electrical shock, and the correct polarity must be observed when connecting wires. The fused positive lead includes a 15-amp ATC blade fuse that should never be bypassed or replaced with a higher-rated fuse. Following these precautions ensures safe installation and protects the aircraft's electrical system.
The controller is covered by a five-year limited warranty, while the solar panel is covered by a two-year warranty. Registering the unit within 10 days helps ensure warranty support and access to technical updates.
