The PulseTech SP-25 SolarPulse 25-Watt Solar Charger is used to charge, maintain and desulfate any individual 12-Volt lead-acid batteries (VRLA, AGM, gel and flooded cell) as well as two to four 12V batteries connected in parallel, making it ideal for heavy duty applications ...The PulseTech SP-25 SolarPulse 25-Watt Solar Charger is used to charge, maintain and desulfate any individual 12-Volt lead-acid batteries (VRLA, AGM, gel and flooded cell) as well as two to four 12V batteries connected in parallel, making it ideal for heavy duty applications. SolarPulse's higher efficiency, higher quality crystalline silicon cells pack more power per square inch and have a longer life than standard amorphous ''thin film'' cells. That means you can get the power you need in a sturdier, smaller-sized solar panel.
The SP-25 plastic coated panel is virtually indestructible and impervious to weather and age.
