Can you charge a dead 12 volt battery?
In order to fix a dead battery that is still carrying a good amount of voltage, driving around might be all you need to do. As we said before, the alternator will recharge the battery while your car is in motion. Jump starting your car is an effective method to fix this problem.
Can you recharge a dead deep cycle battery?
From a pragmatic standpoint, quality deep cycle batteries are engineered to be discharged and then recharged to full capacity. Don’t be conservative with your batteries on the water, and when you’re back on dry land, recharge with a Minn Kota onboard charger to intelligently restore them to full capacity.
What should the voltage be on a dead battery?
Most automotive systems are designed for 13.5 volt (nominal) input. The sensors used by the ECU typically use regulated voltage (5 volts is common) that is first conditioned by the ECU itself. Considering that a battery voltage of 11.9 volts indicates that the battery is completely dead, I’d say that’s more than just “low.”
What does 12 VDC mean on car battery?
Put the leads where the cables connect on the battery. Red on the + (positive) and black on the – (negative). It will read 12 VDC when the battery is charged and the engine is off. What could this possibly mean?
Can a completely dead battery be recharged?
There are a few ways to recharge your battery, though the phrase “completely dead” is a bit more difficult to assess. If your car does not start because of a completely dead battery, your only option might be to get a jump start from another car and purchase a new battery in the near future.
Can a car battery run below 12 volts?
Car batteries tend to run 12 or more volts, and if the battery falls below that amount, you could have a dead battery. There are 5 functions of a car battery, and if your car battery is giving you trouble, it might be a good idea to check its voltage.

Is it possible to read the terminal voltage of a dead battery?
It’s possible to read nearly the fully rated terminal voltage on a dead cell if you take a no-load measurement. This is due to the battery’s internal resistance and the loading effect of the measuring device (the theory behind this is complicated and I won’t attempt to get into it here).
