7 Watt Solar Battery Charger Maintainer – 12V | SP-7 SolarPulse


7 Watt Solar Battery Charger Maintainer – 12V | SP-7 SolarPulse

Works with all 12-Volt lead-acid batteries including VRLA, AGM, gel and flooded cell.

  • The PulseTech® SP-7 SolarPulse® 7-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.
  • The 7 Watt Solar Battery Charger provides a full 7-Watts of power in a compact, durable 10.25”L x 8.85”W x 0.25”H solar panel. That’s almost half the size of solar panels used in other solar chargers so that you have the most installation options for your vehicle or equipment.
  • 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 7 Watt Solar Battery Charger model utilizes our unrivaled solar charging system combined with our patented high frequency pulsing circuit, Pulse Technology, to ensure batteries start when needed and lasts up to three times longer.

Pulse Technology reverses the naturally occurring process of battery sulfation – the main cause of battery failure. The SP-7 replaces the power loss from electrical accessories that occurs even when the ignition is switched off dramatically reducing jump starts and increasing battery power. It also replaces the power loss from vehicles that experience short run times between stops, high loads at idle and parasitic drain.

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. An LED light indicates charge so you know when it’s working. The LED shines brightly when the solar panel is in full sunlight and working at optimum level and fades when the panel is exposed to partial sunlight.
