Customer ServiceIn order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
Customer ServiceWhen a battery has been fully depleted, a condition known as deep discharging, sometimes known as over-discharging, takes place. A battery stores potential electric energy when it is charged, and when it is drained, the charging process is reversed and the potential electric energy is used to power the electric components.

Customer ServiceThe most notable difference between Deep Cycle and Lithium-Ion batteries is that lithium battery capacity doesn''t rely on discharge like the lead-acid deep cycle batteries. Lithium-Ion batteries deliver the same amount of power throughout the entire discharge cycle, whereas a deep cycle battery''s power delivery starts out strong but dissipates.

Customer ServiceDeep-cycle batteries are designed for repeated deep discharge and recharge cycles, unlike regular lead-acid batteries meant for lighter loads. Look for labels mentioning "deep-cycle," "marine/RV," or battery specifications with higher reserve capacity ratings (usually over 100 minutes). Deep-cycle batteries also tend to be thicker with sturdier plates to withstand
Customer ServiceWhen removing the load after discharge, the voltage of a healthy battery gradually recovers and rises towards the nominal voltage. Differences in the affinity of metals in the electrodes produce this voltage potential even when the battery is empty. A parasitic load or high self-discharge prevents voltage recovery.
Moreover, a battery’s cut-off voltage is temperature-sensitive. The quantity of electricity discharged during deep discharging is actually 1.5 to 2 times greater than the battery’s capacity. It is therefore extremely challenging to recharge the battery after over-discharging because the cell’s internal resistance has grown.
A battery stores potential electric energy when it is charged, and when it is drained, the charging process is reversed and the potential electric energy is used to power the electric components. Each battery has a cut-off point, which corresponds to the voltage at which the battery is fully depleted.
Ning et al. studied the battery capacity loss at different discharge rates (1–3C) and found that the largest battery internal resistance could be achieved at the 3C discharge rate, and the capacity loss is proportional to the discharge rate.
Higher discharge rates lead to increased internal resistance, resulting in more significant voltage drops. For instance, discharging at a rate of 2C can considerably reduce the battery’s capacity compared to lower rates. This information is vital for applications where peak power is needed, such as electric vehicles.
Repeated deep discharges, where the battery is discharged to a large extent, can accelerate degradation. It is generally recommended to avoid discharging batteries below 20% to reduce the impact on battery longevity. By keeping the depth of discharge at a moderate level, you can help preserve the overall health and lifespan of the battery.
