Act 33 tests batteries without disconnecting them

An ACT Meters product story
Edited by the Engineeringtalk editorial team Aug 24, 2009

The Act 33 battery capacity tester will test a range of batteries without the need to disconnect them, which is suitable for situations where a complete system shutdown is not an option.

This is ideal for battery maintenance inspections in a variety of applications, including security, UPS, telecommunications, healthcare and all other emergency back-up systems.

The Act 33 will test any battery between 1.5V and 24V with capacities up to 1,200Ah, including sealed lead acid (SLA), alkaline, nickel-cadmium (Ni-Cd), lithium-ion (Li-Ion) and nickel-metal hydride (Ni-MH).

It allows the engineer to simultaneously measure open-circuit voltage, internal resistance, current, terminal temperature and Ah capacity while the battery is still connected and operating.

The Act 33 includes a data-logging function for monitoring battery condition over a set period in real time and a load test analysis feature for recording how much current is passing through the battery under load conditions.

A built-in comparator enables the engineer to store up to 99 sets of various battery types for testing and analysis.

The Act 33 also allows engineers to download recorded results onto a PC using the supplied RS-232 interface software and print them using the optional Act 300XP thermal printer.

The tester is supplied with a four-terminal test probe for the simultaneous measurement of battery voltage and internal resistance, a heavy-duty crock-clip test lead for testing battery temperature and a clamp adaptor for measuring battery load current.
