Product InformationStore Part Number: SP-12


Replaces: SP-10 (Part# 735X310)

Rated at 750 mA, the PulseTech SolarPulse SP-12 (735x468) charges, maintains and desulfates any type of 12-volt lead-acid battery system including AGM (maintenance-free), flooded cell, gel cell and VRLA. The SP-12 solar charger and maintainer is designed to keep up to four lead-acid batteries connected in parallel in peak condition. It utilizes PulseTech’s unrivaled solar charging system combined with a patented optimized high-frequency pulsing circuit to ensure batteries always start and release maximum power when needed no matter how long they’ve been sitting unused. Patented Pulse Technology extends battery life up to 3 times.

The uniquely designed SolarPulse solar panels are made of highly efficient monocrystalline silicon photovoltaic cells, encapsulated with a clear polyurethane plastic coating (instead of a breakable glass coating), and mounted on a laminated aluminum substrate back plate that is less than 1 ⁄4" thick. This makes the panel virtually indestructible, impervious to weather and resistant to damage. PulseTech’s higher efficiency, higher quality monocrystalline silicone 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.


  • Works on ANY 12V lead-acid battery (VRLA, AGM, gel and flooded cell)
  • Peak Output Current 750 mA.
  • Provides approximately 3 to 4.5 Amps a day (dependent on sunlight conditions).
  • Keeps up to 4 batteries connected in parallel in peak condition!
  • Maintains batteries at full state of charge
