BU-501: Basics about Discharging
A parasitic load or high self-discharge prevents voltage recovery. A high load current, as would be the case when drilling through concrete with a power tool, lowers the battery voltage and the end-of-discharge voltage threshold is often set lower to prevent premature cutoff. The cutoff voltage should also be lowered when discharging at very cold temperatures, as the

Recovery Charge After Deep Discharge
Recovery Charge After Deep Discharge When a battery has been subjected to deep discharge (commonly referred to as over-discharge), the amount of electricity which has been discharged is actually 1.5 to 2.0 times as great as the rated capacity of the battery. Consequently, a battery which has been over-discharged requires a longer charging

Protection Mechanisms For Batteries & Their Charging Systems
During the charging process, over-temperature condition may occur if the charging current is much higher than recommended. For example, in a lead-acid battery, a 0.1 to 0.3°C charging rate is considered quite safe, while for a Li-ion battery, a 1°C rate is considered alright. Anything higher than these values may heat up the battery.

6 FAQs about [Battery over-discharge recovery charging current]
What is a battery over-discharge?
The over-discharge refers to the behavior of continuing to discharge a battery when it reaches the discharge cut-off voltage , . The over-discharge can occur in a variety of situations, such in cells without BMS in various aerospace and implantable medical devices.
What happens if a battery is discharged to 0 volt?
When a battery is discharged to 0 V and stored at 0 V, the anode still retained a certain amount of reversible lithium inventory, and the potential rose slowly and was lower than the dissolution potential of Cu (Fig. 9 d–f). The RLE remained nearly 100% capacity retention rate (CRR) after three 3-day zero-volt storage. Fig. 9.
When does a battery discharge stop?
The discharge is stopped when the output terminals are shorted. The discharge restarts when the short is removed. The safety circuits in the diagram above are for overcharging, overdischarging, and overcurrent for a single cell battery-pack. Please consult Panasonic when two or more cells are connected or when actually using this or other circuits.
What happens if a battery is cycled below 1.8 volts?
However, Chen et al. exhibited that cycling the LCO|LTO battery below 1.8 V leaded to accelerated battery degradation, which is mainly attributed to the thermodynamic losses of the LCO. The use of low-potential cathodes and high-potential anodes induces the reduction in the energy density.
Can a battery be overcharged by a voltage cutoff?
The rapid advancement of battery management system technology has basically avoided the possibility of overcharging by voltage cutoff , , , however, LIBs face challenges caused by over-discharge due to their self-discharge characteristics .
What happens if a graphite battery is overcharged?
In the study of Zheng et al. with LFP | Graphite cells, the degradation and regrowth of SEI film results in 24.46% capacity fading when over-discharged to 0.0 V in 110 cycles, while Cu dissolution was not found. The dissolution of Cu and the degradation of SEI induce irreversible damage to a working battery.
