Can you leave a battery charger on overnight?
Even though there is no risk of overcharging with the use of a high quality charger, the battery should not remain connected to the charger for more than 24 hours. A full charge is usually achieved by charging overnight. Even after a deep discharge, some chargers enable at least partial reconditioning of the battery.

What’s the normal parasitic draw on a car battery?
On newer cars the parasitic draw is slightly higher than on older cars due to the increase of electronic systems. A normal parasitic draw is about 50mA or 0.05 amps, but the range can be anywhere from about 0.03 to 0.085 amps (30-85mA).
How can you tell if your car battery is dead?
9. If your [&battery&] is: Reading 0 volts, chances are the [&battery&] experienced a short circuit. Cannot reach higher than 10.5 [&volts&] when being charged, then the [&battery&] has a dead cell. Fully charged (according to the [&battery&] charger) but the [&voltage&] is [&12&].4 or less, the [&battery&] is sulfated.
