| Take control of your batteries. Do you know how long that set of
batteries will really last?? Is that battery still good?? Will this
battery take a charge at all?? Answer those questions and take control of your batteries with the C9000. How long will this set of batteries last in my device?? The C9000 will test your cells for actual capacity, not just what is printed on the label. This charger will actually put your batteries through a test/refresh cycle and then display exactly their tested capacity. No more guessing how good those batteries are. You can then use that information to put together groups of closely matched cells to get the run time that you expect. Is this battery any good?? Will this battery take a charge at all?? Use the C9000 to run it through a test/refresh cycle. Find out for sure. If the cell does test below expectations you can then run it through a recondition cycle to try and bring it back to life. This can happen when NiMH cells sit unused for an extended period. Due to self discharge they can become completely depleted. It may take several charge/discharge cycles to bring them back to life. No problem, the C9000 does that with ease. |

Battery test informationWhat are the best batteries??How do batteries compare??The first column displays test results from battery analyzer tests. This device allows testing at selected current load. Time, Voltage and Current are logged. Results are battery discharged capacity (mAh) and discharged energy (mWh). For all NiMH cells the test termination voltage is 0.90V. The test current for AAA and AA cells is 500 mA. Test current for C and D cells is specified in the test results. This allows comparison of the cells with no other factors influencing the results as may be the case in the testing charger results. This can be compared to the results from the individual charger tests to see how the chargers perform. Note; only the C9000 and BM200 are capable of testing the C and D cells with adapters. This is due to firmware restrictions in the La Crosse Techology and AccuPower chargers.I use the chargers available with a test function. This function displays the actual capacity of the cells under test. All of the chargers perform this test basically the same way. First the test parameters are set. Then the test cycle begins. The cells are charged to full using a -dV algorithm to detect full charge. Then the cells are discharged at the test rate while timing the discharge. When a predetermined voltage is reached (0.9V) then discharge is terminated. Then the cells are charged again. At the end of test cycle the capacity measured during the discharge is displayed. All cells are retail new and are run through 2 recondition cycle before capacity testing is performed. In all tests 4 cells are tested and results averaged. Please note that due to variations in manufacturing and testing any results within several percent of value should be considered identical for these tests. This chart will grow as I get more batteries to test. Enjoy the results. Note; the BC-9009 and BC-1000 are identical except for the color of the case. Both have same circuit board revision and firmware revision. Batteries are ranked from results of the Battery Analyzer tests. AA Cells

Internal resistance measurement.
Batteries can be modeled as a voltage source in series with a resistance. In practical terms internal resistance gives an indication of how well a battery can supply current to a load without the cell voltage dropping. Low internal resistance and low cell voltage drop. High internal resistance and high cell voltage drop. So if you are looking for a battery that can delivery high current to the load you want a battery with low internal resistance. In this test internal resistance is measured using the DC method. A programmable current source is used as the load so that load current can be precisely controlled. Cell voltage is measured by a high accuracy bench DVM. The results give a change in cell voltage for each current load. This data is plugged into ohms law to calculate the equivalent resistance. Internal resistance in the chart below is given in mili-ohms, that is thousandths of an ohm. Lower is better.AA Cells

So what does it mean??
Example: If the internal resistance is 50 mΩ and you need to drive a load of 1 A and assume a no load cell voltage of 1.25V then under that load cell voltage would drop to 1.20V.
If you need to drive a 2A load then the cell voltage would drop to 1.15V.
If the internal resistance is 100 mΩ at 1A load then cell voltage would drop to 1.15V. Under 2A load it would drop to 1.05V.
Of course the C and D cells performed the best.
All of the AA batteries seem to range form fair to good in terms of internal resistance.
The AAA batteries did not test as well but of course they have far less electrode surface area. However most put up a respectable performance.
Note: Only the BM200 charger has internal resistance measurement function.
