- I notice when charging my car battery that the amps goes up to about
- 5 when battery is dead and gradually goes down to nothing as the battery
- is charged. How does a battery charger sense this? The internal resistance
- of the battery? (but no, becuase that goes down as the charge goes up,
- doesn't it?). What sort of sensing circuit is used to reduce the amperage?
- Anyone know?
