Cellchecker™ Lead Acid Pulse Load Battery Tester

A product from SDI

Key Features and Benefits

Ideal for maintenance of fire and security alarm systems.
Fundamentally different to traditional testers.
Accurate pulse load testing.
Tests ability to deliver current and maintain voltage under load.
Tests battery performance – not just voltage or internal resistance.
Identifies weak or failing batteries.
LED indicates percentage of remaining battery capacity.
Fast Test Time – approximately 15 seconds.
Easy to use.
Battery safe – does not damage or drain the battery.
Accurate results on new, partially discharged & stored batteries.

How it Works

The Cellchecker™ uses pulse load technology to provide a comprehensive test of a battery's state of charge and condition. It assesses a battery's remaining power capacity by measuring its ability to maintain voltage levels while under load. This provides a more accurate assessment than voltage readings alone.

The tester makes an assessment based on these readings and displays the remaining percentage capacity of the battery. The duration and repetition of the load test cycle vary depending on the battery type, design, chemistry, and application to ensure the power demand during the test is comparable to normal operation.

Highest Standards:

"...it is imperative to determine whether a battery would be able to sustain the necessary load for the required amount of time without failing. Practically, only load testing can achieve this properly..."

"...battery testers that test a battery under no load do not accurately simulate the battery's performance in operating conditions..."

"...under load, the battery shall perform in accordance with the battery manufacturer's specifications..." - NFPA 72-2002: Table 10.4.2.2

Instructions for Use

Turn on the power switch (located on the right-hand side of the unit).
Select the type of battery to be tested by pressing the MODE key until the LED next to the correct battery type is illuminated.
Connect the test leads to the battery terminals, ensuring a good connection with the red lead connecting to the positive terminal (+) and the black lead connecting to the negative battery terminal (-).
Press the TEST key.
LEDs will flash in sequence indicating the test is in progress. When the test is complete, one LED will remain lit indicating the battery's state of charge or remaining capacity.
Make two tests at five-second intervals to verify that the battery has stabilized and is delivering consistent power.
Turn off the power switch.
