Battery Analyzer – Introduction and Comparison

Oct 29, 2020   Pageview:91

Proper maintenance and management of the equipment that we use at home are always crucial. It is always advisable to check your battery frequently. This helps prevent damages and other effects that can shorten the lifespan of a battery. Just the same way we visit the hospitals for body check-up, always ensure that your battery gets the same treatment.

Due to the need to check the health of a battery, battery analyzers were introduced. Battery analyzers were designed to ease the issue of battery analysis. The analyzers became famous in the 1980s and 1990s.

The battery analyzers were initially devices used to restore nickel-cadmium batteries degraded by memory effects and reduced capacity that emerged when the batteries were not fully discharged. But since then, there have been developments and improvements to battery analyzers. Battery analyzers are now used in a wide range of batteries and not just nickel-cadmium batteries.

Battery analyzers are there to serve you. Therefore, you have no reason to have a battery that you do not even know its state. We will discuss a battery analyzer's functions, its difference with the battery tester, and the battery analyzer's accuracy. Therefore, follow the article through and learn.

What does a battery analyzer do?

We know you are asking yourself what might be the function of a battery analyzer. The battery analyzer has several functions.

?They are used to discharge a battery to measure capacity.

?They also run the battery through charge.

?The analyzer helps in discharging the battery, wait, and repeat cycles.

?It is used to measure the internal resistance of a battery.

?Discharge of the battery at distinct current amounts to stimulate actual usage patterns

?Rejuvenating the battery that has been overcharged is also another function of a battery analyzer.

Those are the main functions of a battery analyzer. Therefore, you now know what you should be using your analyzer for.

What is the difference between a battery analyzer and a battery tester?

When it comes to battery testing devices, two terms often emerge; battery analyzers and battery testers. The two terms are used similarly, but they generally refer to two distinct types of gadgets.

Battery Analyzers

Battery analyzers check the batteries in service and predict replacement. The analyzers are used to analyze a wide range of batteries as part of fleet management and assurance of battery integrity. Frequent battery analysis is needed because batteries seem to have a shorter lifespan than the equipment it powers.

Battery analyzers act as security to retire packs when they work below-set performance criteria. An excellent example of a battery analyzer is the Cadex C7000 series that accommodates lead-, nickel-, and lithium-ion type of batteries. Its program is automated and thus operates in stand-alone mode or with computer software.

The most used program of battery analyzer is Auto. This program ensures that it charges the battery, apply a discharge to measure capacity, and ends the program with a final charge. Another program is Custom that puts the battery through a unique type of charge, discharge, wait, and repeat.

The life-cycle program runs the battery in cycles until the capacity has reduced to the present target capacity while counting the cycles. It is used to find the durability of the battery. Ohm Test, on the other hand, evaluates the internal battery resistance. It also checks the Runtime discharges of a battery at three distinct current levels to give a unique usage pattern.

Other programs include Self-Discharge that tests losses of charge, and Prime cycles the battery until the maximum capacity is achieved. Prime also verifies the extra capacity before a charge. The connection of the battery analyzer is quite a challenge. They are designed with fancy gadgets that have springs and levers. It makes it so complicated that the inventor can only operate it.

Battery Tester

Battery test systems provide a wide range of test functions for research laboratories. The applications are life-cycle testing to speed battery loading and testing the durability in the field. It also checks the balance of several cell pack in field simulation. These tests can be made automatically with a custom program that the user can compose.

For instance, Cadex C8000 captures load signatures of mobile phones, laptops, and power tools, and then uses the simulated loads to verify battery runtime as if used in real-life situations. The device is also able to monitor individual cells with the assistance of floating analog inputs. It has a double Power Port Cable that extends the discharge current from 10A in each station to 20A by similar function.

Battery testers can run a wide range of measurements. Most tests done include tests of actual battery capacity, battery cycle life testing, and characterization of battery DC internal resistance. Others are Hybrid Pulse Power Characterization (HPPC) tests, electric double-layer capacitor (EDLC) tests, lithium-ion capacitor (LIC) tests, and many other tests.

Battery testers manage capacity tests at the final battery charge. Also, the discharge rate gets a more accurate image of capacity than standard tests, which occurs at higher charge and discharge rates. The same thing applies to battery cycle life tests. Battery testers may gauge dc internal resistance using more than one method because battery internal resistance depends on loading current.

The battery testers perform more than what battery analyzers do. Testers are more complicated; thus, there is a big difference between battery testers and battery analyzers. This is the main reason why battery testers are used in chemical battery laboratories.

Are battery analyzers accurate?

Analyzers base their testing on the CCA rating of the battery. Therefore, an accurate test can be performed if the initial battery label is torn out or is missing. Thus, the accuracy of the test depends on other factors.


Ensure that you always do the battery analysis at least twice annually. This ensures that you know if your battery is about to die or if it has some defects. It is crucial because you cannot get stuck if you know the exact state of your battery. You can go the analysis in a short period. Visit the nearest battery store if you get more on analysis.
