Restore and Maintain: Keep 12V lead-acid batteries in seldom-used outdoor vehicles and equipment ready to go any time.

Unique Design: SolarPulse's higher-quality crystalline silicon cells pack more power per square inch and have longer life than standard amorphous "thin-film" solar cells. This uniquely designed solar panel is made of highly efficient proven crystalline silicon photo-voltaic cells, encapsulated by a clear polyurethane plastic coating, and mounted on a laminated aluminum substrate back plate that is less than 1/4" thick.

Durable and Powerful Performance: It is virtually indestructible and impervious to weather and age. The SP-3 charging system provides a full 3-Watts of power in a small durable size (4.7''L x 9.45''W x 0.25''H). For ultimate performance, it should be used on a single 12V lead-acid battery to replace the power loss from electrical accessories (that occurs even when the ignition is switched off) and to reverse naturally occurring sulfation buildup on the battery plates. The SP-3 is a higher-watt version of our SP-2 Solar Charger (2-Watt). SP3

The secret to our success is our patented pulse waveform, which removes and prevents the buildup of lead-sulfate deposits on battery plates. That primes the battery to accept and store maximum power.

Long trusted by the military, our tech is ideal for anyone who wants to get more out of their equipment.

If you have issues with dead batteries say no more.

This thing is a power house, man this charges like there is no tomorrow. If you have issues with dead batteries say no more.

Now Even Better

Purchased my first one about 8 years ago and battery is still going strong. Just purchased another one to maintain cranking battery for a trailer mounted generator. Noticeable improvements include connectors for the solar panel and the battery cable. Appears general quality is better as well. No problems putting it into service and it's holding battery above 13.2 volts. A great product when you need to keep a critical battery ready at all times.
I have purchased several other PT products and always been happy. Uncompensated review by retired engineer.
