The reason why the battery has poor circulation at low current
The intrinsic reason for the poor cycling stability of vanadium-based materials at low current densities is that the process of Zn 2+ insertion/extraction is accompanied by vanadium dissolution, structure collapse, and by-products.

Alternator Failures: Low Voltage To The Battery
The normal key-off current drain on a battery may be as high as 300 to 400 milliamps right after the engine is shut off. But as a rule, the key-off current drain should usually be less than 50 milliamps one hour after the engine has been shut off and left undisturbed. Once all the modules go to sleep, the current drain drops significantly.
