Powering Up - The Importance Of Battery Testers
Battery testers are used to ascertain the power remaining in a battery before use.  The advantage of this is to prevent machinery failing on the job, causing downtime and loss of production, as well as increasing safety.


Battery testers operate on a variety of parameters such as voltage, terminal temperature and resistance.  In all maintenance servicing, a battery test is essential, and is an important preventative maintenance measure.


Electrical machinery in manufacturing, safety equipment such as fire systems and communication devices such as satellite phones and two way radios, especially for use in remote locations, are all areas that need battery testing performed on a regular basis. A battery tester such as the Flukebt521 for example, measures voltage, internal resistance, and strap resistance identifying early battery failure or installation problems.


Digital and electric battery testers allow an increased monitoring of battery performance.  They can check the battery condition in seconds while it is in service and measure battery resistance, voltage, current and temperature concurrently at the same time. Digital battery testers will also store information and data via manual and auto data memory offer a USB PC Interface for easy data transference.


Batteries Everywhere

Batteries have an increasing place in many industries ranging from powering mobile applications such as electric bikes, cars, buses and boats, and tools like drills, screwdrivers and chain saws to stationary solutions that support the electricity grid and local energy systems. A whole range of household power tools also operate by battery power.


Testing each battery before installation can save problems when one battery fails but the others are running.  Batteries can produce very different power results even within the same pack, same manufacturer or batch – a battery user cannot rely on each battery to produce the same amount of power.  Using a battery testing device takes away the guesswork and inherent risk of relying on a battery having power for essential tasks.


Atmospheric Effects

Certain conditions can also affect a battery’s performance  and these characteristics can be pre-established by use of a battery tester.  Tests can determine the capacity at different charging and discharging rates in different thermal conditions, internal resistance or impedance at different life stages, the life cycle and robustness of the battery and the heat generation during charging and discharging processes.


Most electronic battery testers can provide an accurate assessment of the battery condition and capacity even when a battery is significantly discharged.


Digital/electronic battery testers are calibrated to properly assess the different battery compositions that have been introduced in the last decade.


New battery chemistries, such as AGM and Gel Cell types, are becoming more popular with auto manufacturers while other newer types of battery such as Spiral Wound batteries, are gaining in popularity in a wide number of applications.  Digital testers are calibrated to test different battery types for more accurate assessment of battery conditions.


An accurate and reliable battery tester is an indispensable part of any maintenance program in the workplace and will perform the task of ensuring a reliable power source for machinery, power, communication and transport.
