Cellchecker

Cellchecker™ is ideal for testing batteries in fire and security alarm systems. Using pulse load technology it provides a comprehensive test of a battery’s state of charge and condition.

This microprocessor controlled unit, tests popular SLA batteries and after a fully automatic test cycle displays the percentage of remaining battery capacity on the LED bar display.

FEATURES

• Ideal for maintenance of fire and security alarm systems
• Fundamentally different to traditional testers
• Accurate pulse load testing
• Tests ability to deliver current & to 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

WHY PULSE LOAD TESTING?

Battery voltage alone is not a reliable parameter for determining remaining capacity and condition; it also does not indicate whether the battery will be able to deliver power when placed under load. Rather than simply displaying a voltage reading, cellcheckerTM determines a battery’s remaining power capacity by measuring its ability to maintain voltage levels while under load. The tester then makes an assessment based on these readings and displays the remaining percentage capacity of the battery.

Pulse load testers verify that a battery can deliver power by actually making it deliver power. The duration and repetition of the load test cycle varies depending on the battery type being tested. Factors that are considered when determining the size and duration of the pulse load are battery design (high rate or low rate), battery chemistry, and the battery’s typical application. This helps ensure that the power demand on the battery during the pulse load test will be comparable to what the battery experiences under normal operation conditions.

"Batteries and their connections should be examined and momentarily load tested with the mains disconnected... to ensure that they are in good serviceable condition and not likely to fail before the next service visit..."

"...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
