“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.
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.
If discharged under this voltage, the cell may be permanently damaged. To get the precise value of min discharge voltage, consult the datasheet of your cell. This requires an update in 2020: For most modern Li-ion cells, 2.5 V is the discharge limit.
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.
The discharge voltage level depends on the cell chemistry. The minimum discharge voltage varies between various sites, datasheets, etc. but 3.0 V - 2.7 V is an empirical value. If discharged under this voltage, the cell may be permanently damaged. To get the precise value of min discharge voltage, consult the datasheet of your cell.
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.
One of the main advantages of AGM batteries is that they have a low self-discharge rate, which means that they can hold their charge for a long time without needing to be recharged. If an AGM battery is deeply discharged, …
