Testing CR123A (CR17335) batteries at high current
rates
Method
1. New Batteries are purchased from a retailer to make sure they are fresh.
2.
This test is not to compare batteries for normal operation, they are designed for low current draw and these tests are for high
current draw. This information is to help design engineers know what to expect when the batteries are used under these
circumstances.
3. The performance rankings may be different for low current applications.
4. Note that for most
applications these discharge currents are extreme, at lower discharge currents you will get much higher voltages and longer run
times.
Thanks to David Vanhorn from ESI for supplying these data.

Here are the CR123A discharge curves at 0.7 Amps. If you need more than 2.6 volts to run your circuit, these
won't be useful at 700 mA. |
|
 |
At 1.5 amps the curves are still pretty flat, but run around 2.3 volts on
average.
......................... |
|
 |
At 2.2 amps the AU comes back to life, since these are non-rechargeable cells we can't go back and test the
same cell. |
