12-Watt PulseTech SolarPulse Battery Charger & Conditioner


  • Half the size of most 12 watt panels, low-profile, durable design
  • Works with flooded, AGM, and gel cell batteries
  • Extends battery life by preventing sulfation buildup on battery plates
  • Prevents battery power loss on stored vehicles
  • Five-year Manufacturer’s Limited Warranty


Keep your 12 volt lead-acid batteries in peak condition with PulseTech’s 12 watt SolarPulse charger. Both a trickle charger and a pulse conditioner, the SolarPulse prevents damaging sulfation buildup on the battery plates, without requiring any outside electrical power.

The SolarPulse is perfect for keeping recreational vehicle or marine batteries conditioned during off-season storage, ensuring your backup generator is always ready when you need it, and much more!


  • Ideal for virtually any kind of vehicle and equipment in areas without access to electrical power, including motor carriers, rail cars, sailboats, recreational vehicles, gensets and more.
  • Unique industrial-strength 12-watt panel is almost HALF THE SIZE of comparable chargers yet provides full 12-watt power
  • Smaller panel provides more installation options
  • Low-profile industrial-strength solar panel mounts flat (no frame required)
  • Works with every type of 12-Volt lead-acid battery (flooded, AGM and gel cell)
  • Cleans battery plates of large damaging lead-sulfates so batteries can accept, store and release MAXIMUM power when you need it
  • Helps offset energy-robbing key-off parasitic loads)
  • Prevents the normal loss of battery power on vehicles stored outside no matter how long they sit unused – even months at a time
  • Helps extend battery life up to 3X longer
  • Five-year manufacturer, limited warranty

From The Manufacturer:
The PulseTech® SP-12 SolarPulse® 12-watt Solar Charging System charges and maintains any 12-Volt lead-acid battery (VRLA, AGM, gel and flooded cell) and solves battery problems for anyone using two batteries connected in parallel. Pulse Technology reverses sulfate crystal buildup on the battery plates extending battery power and life up to 3 times. SolarPulse’s higher efficiency, higher quality crystalline silicon cells pack more power per square inch than competitive products. Plastic-coated panels are virtually indestructible. The SP-12 is a higher watt version of the SP-10 Solar Charger, 10W.

To understand how pulse conditioning works, you need to know that batteries ‘wear out’ because the electrolyte inside them slowly crystallizes over time, building up lead sulfite deposits on the battery plates. These deposits effectively insulate the battery plates, making it harder and harder for the battery to create electrical current. Eventually, the battery will not hold enough of a charge to function properly. This photo shows the results of a 4-year test conducted by PulseTech, showing how pulse charging technology helps prevent this damaging buildup. After 4 years of every other day charging/discharging, the PulseTech charged battery plates still look almost new.
