Battery Drain Tester w/ Memory Saver - OTC Tools and Equipment

The OTC 3382 Battery Drain Tester w/ Memory Saver is a crucial diagnostic tool for professional automotive technicians and mechanics, designed to accurately identify parasitic battery drains without compromising a vehicle's electronic systems. This robust unit provides immediate and precise feedback on current draw, streamlining the diagnostic process and preventing the unnecessary replacement of batteries or charging system components.

Key Features

• Accurate Parasitic Drain Diagnosis: Delivers instant feedback on potential parasitic battery drain conditions, helping technicians quickly identify issues that lead to battery discharge and eliminate guesswork.
• Integrated Memory Saver Function: Protects the vehicle's computer memory by supplying power to its electronics when the battery cable is disconnected. This preserves stored fault codes, driveability parameters, and programmed electronic settings like clock, radio, and seat positions.
• Maintains Vehicle Sleep Mode: Engineered to keep the vehicle's computer in its "sleep mode" during testing, ensuring that the measured parasitic drain is accurate and not influenced by active modules.
• Convenient Power Input: Plugs directly into the vehicle's cigarette lighter or auxiliary power socket to provide continuous power to electronics, facilitating seamless memory preservation during battery disconnection.
• Overcurrent Protection: Features built-in overcurrent protection to safeguard the tester from damage and prevent blown fuses, ensuring reliability and longevity in a professional workshop environment.

Applications

This tool is indispensable for automotive professionals troubleshooting unexplained battery drains in modern vehicles with complex electronic systems. It enables mechanics to efficiently diagnose the source of parasitic draws, preventing repeated battery failures and the need for time-consuming reprogramming of vehicle settings. The memory saver function makes it ideal for any service involving battery disconnection where preserving vehicle data is critical.
