Battery Service Wasabi Racing carries a full line of Interstate Batteries. If you suspect your car battery is not working properly, stop in and have us perform one of our diagnostic tests. Diagnostic Tests: Load Test:This test is a 15 second discharge of the battery at a ½ cold cranking amp level. A more accurate testing method than a voltmeter or a hydrometer, the load test is often required to determine if a battery is still viable. Specific Gravity Test:This test is preformed with a hydrometer. A hand held tool which determines the state of charge in a lead acid battery with great accuracy. Open Circuit Voltage Test (OCV):An OCV test is performed with a voltmeter. It is the only way to determine the state of charge in a sealed no-maintenance battery. We do not recommend an OCV test substitute for the Specific Gravity Test in a serviceable battery. The Specific Gravity Test is the more accurate test. We have a state of the art MidTronics battery charging system. If your battery is low or dead, we can recharge it in 40 minutes or less. Using MidTronics Patented RTD (Real Time Diagnostics) technology, our system continuously tests and monitors the battery during fast charging sessions. This ensures your battery is charged quickly and safely.
