I have a battery that initially failed to charge (example 4 on https://help.vex.com/article/142-how-to-interpret-error-messages-with-the-v5-battery), but charged correctly after resorting to using the reset button. Afterwards, the initial charge showed the indicator lights working correctly. After the second charge a press of the test button shows a solid green for lights 1 and 3 (with 4 being the one closest to the test button.)
Has anyone seen this pattern? Does anyone know what it might mean? @jpearman
I have already contacted vex support. Their answer (which I find lacking) was:
Actual error messages are usually represented in color red, since the light are green I can say the battery should work just fine.
Please proceed to use the battery as normal.
