Key Features of the Associated Equipment 9425

20-Amp Intellamatic® III Smart Charging

The 9425 features Intellamatic® III microprocessor-controlled charging, which continuously monitors battery condition and automatically adjusts the charging process for maximum efficiency. Benefits include automatic charge regulation, faster and safer charging, overcharge protection, improved battery life, and minimal technician supervision.

ESS™ Electrical Stability System Power Supply

One of the biggest advantages of the 9425 is its Electrical Stability System (ESS™). The charger can operate as a 20-amp regulated power supply, providing stable voltage during:

  • ECU programming
  • Module flashing
  • Extended diagnostic procedures
  • Electrical troubleshooting
  • Battery replacement

Maintaining consistent voltage helps protect sensitive vehicle electronics and reduces the risk of programming interruptions.

Built-In Battery Analyzer

The Associated Equipment 9425 continuously evaluates battery condition throughout the charging cycle. Its patented diagnostic technology helps identify weak batteries, defective batteries, charging status, battery health, and batteries requiring replacement. This allows technicians to make accurate service recommendations while avoiding unnecessary battery replacements.

Dead Battery Override

Some batteries become so deeply discharged that automatic chargers cannot detect them. The Dead Battery Override function allows technicians to manually initiate charging, making battery recovery possible in many low-voltage situations. Ideal for deep discharge recovery, sulfated flooded batteries, long-term vehicle storage, and low-voltage battery service.

Compatible with Multiple Battery Types

The Associated Equipment 9425 is designed to safely charge a wide variety of 12-volt lead-acid batteries, including:

  • Standard Flooded Batteries
  • AGM (Absorbent Glass Mat)
  • Gel Cell
  • Sealed Lead-Acid (SLA)
  • Spiral Cell Batteries
  • Optima®-style batteries

This versatility makes it an excellent choice for servicing both passenger vehicles and commercial equipment.

Portable Professional Design

Unlike larger shop chargers, the 9425 features a compact, portable design that's easy to move wherever charging is needed. Additional professional features include heavy-duty 300A insulated clamps, polarity protection with Stop/Go® indicator technology, durable industrial construction, 6.5-foot charging cables, and everyday professional-use durability.
