While one of the major advantages of lithium batteries is that they can be discharged to near empty, many say completely empty (0% SOC – State of Charge), this is not true regarding lead acid batteries. Discharging a deep-cycle lead acid battery below half its rated capacity (50% SOC) will damage the battery, reducing its storage capacity and

An Overview of Lead-Acid Batteries | Battery Builders

Lead-acid batteries are rechargeable batteries that use lead and sulfuric acid to charge and discharge electrical energy. When lead is submerged in sulfuric acid, it creates a controlled chemical reaction. The reaction then causes the battery to generate electricity. This reaction can then be reversed to recharge the battery later on. The main materials needed to build a lead

Risks of charging an empty lead acid battery from 10 v

$begingroup$ A lead-acid battery that "suddenly" loses 2V has probably developed an internal short in one cell. It may be possible to blow out the short by applying short pulses of high current -- preferably to just that cell if you can get access to its terminals. But in the meantime, that cell has been completely discharged by the short, so recharging it relative to
