The PulseTech® SP-12 SolarPulse® Battery Charger & Maintainer supplies pulsed current to charge, maintain and desulfate any 12V lead-acid batteries including VRLA, AGM, Gel and flooded cell on outdoor vehicles & equipment, without danger of overcharging or overheating. It is ideal for charging 3 to 4 12V lead-acid batteries connected in parallel and provides a full 12-watts of power, to ensure that your batteries remain in peak condition. This solar battery charger maintainer is virtually indestructible. It features a solid LED light - indicator of full sunlight/working at optimum level. The light fades when the panel is exposed to partial sunlight. Reverse polarity protected. Patented Pulse Technology extends battery life up to 3 times.

The SP-12 solar panel (12.41"L x 9.85"W x 0.2"H) comes with a 3' box-to-lug wire and 17' box-to-panel wire.

The SP-12 is a higher watt version of the SP-10 Solar Charger, 10W.



The SP-12 solar charger combines PulseTech’s patented, high frequency Pulse Technology with microprocessor controlled intelligent charging algorithms to charge, condition and maintain vehicle and equipment batteries. Pulse Technology reverses the naturally occurring process of battery sulfation - the main cause of battery failure. This allows batteries to accept, store and release maximum power all the time extending battery life up to three times.

If you've used solar chargers before, you know it's important to choose the right solar panel for the amount of power you need and the size and place of the mounting location. In the past to get the power you need, you had to struggle with panels that are too big, too bulky and too fragile. With SolarPulse, you get the power you need with the most installation options for your outdoor vehicles and equipment. SolarPulse's higher efficiency, higher quality monocrystalline 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. Instead of a breakable glass coating, SolarPulse's solar panels are protected with a clear polyurethane plastic coating that makes them virtually indestructible and impervious to weather aging and damage from bumps and knocks.
