What Happens If A Battery Is Fully Discharged?

Even though 80 percent of the capacity remains when a car battery dips to around 10.5 volts, the battery is considered to be fully discharged because taking the cycle any deeper will cause irreversible damage to the plates through excessive sulfation.

Does fully discharging a battery damage it?

In a nutshell, you do your phone battery more harm than good if you let it drop to 0-1% charge every time before recharging it.

What happens if battery is deeply discharged?

When the battery is over-discharged, the internal resistance increases. It discharges 1.5 to 2 times the capacity of the battery making it difficult to recharge them. First of all, you should check the present voltage level of the battery, which is lower than the cut-off voltage.

Can a drained battery be recharged?
