From a purely electrochemical perspective, a lead-acid battery can be recharged provided the active material has not undergone irreversible sulfation. However, the practicality of recharging depends on the extent of discharge, the battery's age, and its physical condition. A severely sulfated battery, characterized by crystalline lead sulfate buildup, may not accept a charge effectively. The battery's internal resistance also increases with age, affecting recharge efficiency. Thus, while theoretically rechargeable, the economic feasibility and effectiveness of recharging a heavily discharged or aged battery are often questionable.
A dead car battery can sometimes be recharged, but it depends on the reason it died and the condition of the battery itself. If the battery is simply discharged due to leaving a light on or other minor drain, it can usually be recharged using a battery charger. However, if the battery is old, damaged (e.g., cracked case, corroded terminals), or has suffered a deep discharge (completely drained), recharging may not be possible or may not restore its full capacity. In these cases, the battery will likely need to be replaced. A battery charger will typically indicate when a battery is fully charged. If your battery is consistently failing to hold a charge, it’s likely nearing the end of its life. Always take safety precautions when working with car batteries, as they contain corrosive acid. Wear eye protection and gloves, and ensure proper ventilation.
