PortAlyzer™

Heavy Duty Handheld Battery and Electrical System Tester

The handheld PortAlyzer™ battery and electrical system tester allows users to rapidly, precisely diagnose bad batteries in a discharged state - without the need to charge them first. By utilizing a patented microload testing technology, the PortAlyzer tester can quickly identify bad batteries either individually or in a pack, with no user interpretation or guesswork. The unit also analyzes vehicle starting and charging systems, and is ideal for a range of automotive/LTV and heavy duty/commercial applications.

Battery Testing

• Tests the following battery pack configurations:
- One battery (6V or 12V)
- Two batteries in series (24V); 2, 3 or 4 batteries
in parallel (12V)
- Two banks in parallel, each having two
batteries in series (24V)
• Pack configuration used in algorithim design
• Step-by-step user instructions allow easy
test completion
• Tester-applied loads used on all pack combinations

Electrical System Testing

• 12V and 24V charging and starting system tests
• 12V and 24V diode tests

User-friendly, Shop-friendly

Large, backlit digital display window is easy to read
in all light conditions and displays up to four lines of data
for less scrolling.
Raised, soft-touch keypad is easy to use even with
gloves and is protected by an over-molded enclosure.
15-foot test lead cable enables easy movement and
allows tests to be performed from the cab of the vehicle.

The Microload Difference

PortAlyzer™ tester’s microload
technology applies multiple test
loads to measure a battery’s internal
impedance, capacitive recovery and
other signs of impending failure. For
electrical system tests, microload
technology applies a controlled load
automatically, so users don’t have
to do so manually.

• Saves time by eliminating the need
  to charge a deeply discharged battery
  before testing
• Reduces sensitivity to parasitic drain
  or resistance at terminal connections,
  allowing precision in-vehicle testing
• Ensures compatibility with all battery
  types
