In this era of testing, we collected four famous battery brands and tested five battery categories, including AAA, AA, C, D and 9-Volt. Our goal was to know which battery maker offered the best price of your money. Wee Wee Wee, we used our customs built -in battery test rig and finished longevity of each battery, focused on their voltage production over time, and compared the difference in the price per unit.
Battery performance and voltage drop
Measuring the battery voltage output is much more complicated than just setting up a multimeter investigation at the positive and negative heads of the battery. For example, AA, AAA, C and D batteries are ranked 1.5 volts. If you measure the voltage output directly on the battery, reading can be close to 1.6 volts, which is usually a good mark for a new battery. Even batteries that are no longer usable, can show the value equivalent to a 1.5 volt or higher when it is directly measured. The correct approach is to test the voltage output in the state of the load, such as when the battery is connected to a resistor or a device is strengthened. CNET Labs Match the battery test rig:
CNET Custom Built Battery Test Rig contains five types of battery, including AAA, AA, C, D and 9-wolts. Depending on bread boards and contact battery voltage, allow parallel and series circuit arrangements.

The logic of testing is easy but discovering. Let’s get the whole picture, let’s refresh yourself with a little electronic basics. The number of active load components and circuit arrangements depends on the battery type under the test. We WE of 1.5 volts (AAA, AA, C and D batteries), we set the circuit load parallel, which increased the number of loads according to the battery capacity. This ensures, regardless of the source of power and the number of loads, all the components of the load are exposed in the same amount of voltage with such a power source-in this case, any batteries of 1.5 volts. For example, AA batteries are tested in parallel using three motors, making sure that the three motors get 1.5 volts each.
We use parallel arrangements on our test rig. From left to right, 1.5 volt battery source (either AAA, AA, C or D), a volt meter and motor array. Setup allows two motors to remain active at all times, which increases up to five motors.
9 volt types Wee, we arranged six burden ingredients in the series. The management of the series equally distributes the voltage from power source to all the components. Since each of our fan motors takes at least 1.5 volts, the use of a 9 volt battery provides 9 volts/6 load = 1.5 volts per load.
Six motors have been arranged in the series. 9 volt battery provides equal voltage distribution (1.5 volts) to each load.
After setting the basics, we move towards testing. First of all, we make our multimal probes parallel to connect and read the initial voltage. After that, we make sure that our circuit management is sufficient for the battery type under the test and flip the switch. We start our timers and monitor the test, recording data red out for voltage output every minute until the last last fan spinning is off. We run a “last man standing” competition. In our test logic, the battery that maintains the load management is the longest win. The voltage drop allows us to see how effective the battery maintains high voltage output in view of the test conditions. In this regard, the drop in the voltage is slow, better.
Here are the overall look at each battery’s average discharge time, the results are. Long bars indicate batteries that last longer in our test veins.
Here is another detailed look at these results, with the average voltage readings for each battery during each test with a minute by -minute dip. Once again, we are looking for batteries that run the longest in this test, but in particular, we are more and more slowly looking for voltage drain batteries.
Price per unit
The price of batteries depends on where and when you buy them. That is why, we found a highly economic source for each battery and compared the price per unit. Look at the table below, which we will update regularly:
