The PulseTech® SP-12-OBD-T Temporary SolarPulse® Battery Charger features the OBD (on-board diagnostics) J1939-1 connector for 3-4 batteries connected in parallel. It is designed to charge, maintain and desulfate any 12V lead-acid batteries including VRLA, AGM, Gel and flooded cell on outdoor vehicles and equipment, without overcharging or overheating. The SP-12-OBD-T is ideal for charging 12V lead-acid batteries connected in parallel. A clear polyurethane plastic coating makes this battery charger virtually indestructible. A solid red LED shines steady in full sunlight, and fades in partial sunlight. Reverse polarity protected. The Pulse Technology extends battery life up to 3 times.

The 12-Watt solar panel dimensions are 12.41"Lx9.85"Wx0.2"H. Includes a 3' box-to-lug wire and 17' box-to-panel wire. 10-Year Limited Warranty.

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



This 12-Watt SolarPulse Temporary Charging System provides a full 12-Watts of power in a compact, durable 12.41"L x 9.85"W x 0.2"H solar panel and is ideal for use with 3-4 batteries. The solar panel attaches to the interior windshield with the included suction cups and plugs directly into the OBD port. The set up allows for easy installation and removal in seconds and ensures batteries remain in peak condition no matter how long the vehicle sits unused outside.

Like all SolarPulse models, the SP-12-OBD-T utilizes our unrivaled solar charging system combined with our patented optimized high frequency pulsing circuit, Pulse Technology, to ensure batteries start when needed dramatically reducing the need for jump starts. 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 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 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.
