Default Strange hum when charging battery
Blazer stalled on road. Then batter went dead after warning blinker left on. Charger put on and strange hum comes from engine compartment and battery will not charge.

The hum may be coming from the charger itself, not the battery.

Battery will not take a charge and yeah the chargers do hum some times. But if it is pretty loud more than likely the battery is no good also so get a new one for starters.

You did disconnect one or both of the battery cables before attaching the charger, right??
