“If a battery does become deeply discharged, special care must be taken during the subsequent recharge. With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke.
No, it is not OK to have a Li-Ion deeply discharged at all. 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.
Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.
With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke. Users must therefore ensure that suitable chargers are used and to avoid damaging the devices and batteries.
In the case of storage batteries and deep cycle/leisure batteries, we won’t always discharge to 50%, we’ll go beyond that to at least 60% or 70% sometimes. And sometimes, the battery will be left in a partially discharged state before we can charge it again. Batteries want perfect charge-discharge cycles.
A battery terminal voltage will drop as you discharge it, mainly because the chemical reactions slow down due to depletion. This is nothing to do with the principal of capacitance. At its simplest, you can think of a battery as an ideal voltage source, and a series resistor.
I also understand, as mentioned, that cramming that last bit of charge into the battery to hit 100% is the biggest stress for the battery. With that in mind, I''ll charge to only 95% capacity and also …

What Happens When Your Battery''s Charge Gets Too Low? The most important thing to understand about your battery is that you must keep it charged. If you let the charge drop too low, your battery can become …
When the battery is charged with too low a voltage, or operates at too low a voltage. The acid/distilled water mixture needs a full voltage applied across the battery to mix properly. If …
The charge controller is that oft-overlooked superhero regulating the current from solar panels to your battery bank. But flawed programming or malfunctioning may cause it to incorrectly manage power distribution, leading …
