PulseTech SP-3 SolarPulse 3-Watt Battery Maintainer
The PulseTech SP-3 (Model: SP-3) is a robust 3-Watt solar charging system designed to restore and maintain normal power levels in 12V lead-acid batteries. Utilizing highly efficient crystalline silicon cells, this unit yields 30% more power per square inch than standard amorphous thin-film panels. Integrated with patented Pulse Technology, the SP-3 actively reverses naturally occurring battery sulfation—significantly extending battery life and ensuring reliable starts for seldom-used outdoor vehicles and heavy equipment.
Key Features
- Broad Compatibility: Works with all 12-Volt lead-acid battery types, including VRLA, AGM, gel, and flooded cell.
- Rugged Durability: Protected by a clear polyurethane plastic coating, making the commercial-grade panel virtually indestructible and impervious to weather and aging.
- Active Desulfation: Patented Pulse Technology continuously desulfates battery plates to restore maximum power capacity and extend component lifespan.
- Safety Built-In: Reverse polarity protected and safely maintains batteries indefinitely without the danger of overcharging or overheating.
- Status Indicator: Integrated LED illuminates brightly in full sunlight and dims in partial sunlight to confirm active charging and desulfation.

Frequently Asked Questions
What types of batteries is the SP-3 compatible with?
The SP-3 works reliably with all 12-Volt lead-acid batteries, specifically covering VRLA, AGM, gel, and standard flooded cell types.
Is the solar panel fragile like standard glass panels?
No. The SP-3 uses a commercial-grade clear polyurethane plastic coating instead of breakable glass, making it highly durable and resistant to weather degradation and physical impacts.
How do I know if the panel is working and charging my battery?
The unit features a built-in LED indicator that shines brightly when the panel is in full sunlight and operating optimally. The LED will fade during partial sunlight and completely turn off at night.
