Is there a way to recover a deeply discharged battery?
Many battery chargers will not recognize or charge any battery that has been discharged below 10.5 volts. In this video, we explain a few options that will recover deeply-discharged batteries, including OPTIMA batteries. Loading…
Can a car battery be discharged more than once?
If this is the first time that it has been discharged, you should be able to fully charge the battery and continue using it, but every time it is discharged below that threshold of 10.5 volts, the damage is done.
Can a lithium ion battery be deeply discharged?
It is well known that Li-Ion batteries should not be deep discharged. But sometimes they do discharge deeply. Is it OK for the device to remain in such state for a long time (and recharge again only when the device is needed again after a year)…
What happens when a battery is discharged below its safe voltage?
Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte. The copper ions (atoms?) then in turn can stick on to the anode during charging by chemical reduction and cause dendrites.
Do you have to disconnect your car battery when going on vacation?
Getting a trickle charger is actually much better than disconnecting your battery, though it isn’t the cheapest option. “If someone is going away for a few months over the winter, they should definitely disconnect the battery. It’s the only way to prevent battery drain,” Rashidi said.

What happens to a cell phone battery when it is fully discharged?
By some estimates, frequently fully-discharging can reduce your battery’s capacity by 70% over 300 to 500 charge cycles! The problems start when a battery is fully-discharged (or, for that matter, kept at 100% charge).
How often can a car battery be deep discharged?
That’s why car batteries can only be deep-discharged about a dozen times before they will no longer hold a charge, and deep-cycle batteries can do hundreds.
