Also, keep the top of your battery clean. Loss of charge can travel across dust and dirt. Keep the rag you use. Watch accumulated acid eat holes through it after a few days!  |
I *could* hear sparks from 1.5V AA battery. Maybe not today though ;(
I could hear sparks low enough on car battery that the drainage is “normal”.
I could hear it better than I could see it.
But again, an amp meter is the best because a little drainage is normal.
Also you can get a little inrush, like from charging caps in a radio that can be misleading. You want to see the settled current. And a little is common depending on the setup.
