Common reasons for electric forklift battery capacity degradation

Electric forklifts depend on their battery systems for operation, and capacity degradation is a critical factor that impairs performance and shortens service life. Jianshu New Energy and BYD Forklift, as experts in forklift power solutions, have analyzed the main causes of this capacity decline. Overcharging is one of the most prevalent issues: when batteries are charged beyond their recommended voltage limit, it accelerates the breakdown of internal active materials, gradually reducing energy storage capacity. Undercharging also contributes significantly; repeated partial discharges leave the battery in an unstable state, leading to sulfation—where lead sulfate crystals form on internal plates, blocking ion flow and lowering overall capacity. Deep discharge occurs when forklifts are used beyond their power reserve, putting excessive stress on battery cells and causing irreversible damage to their core components. High temperature exposure, either from hot working environments or improper charging in warm spaces, speeds up chemical reactions inside the battery, wearing down electrode materials faster than normal. Incorrect charging equipment or inconsistent maintenance practices can further worsen degradation. To mitigate these issues, Jianshu New Energy suggests following standard charging protocols, storing batteries in cool, dry conditions, and conducting regular inspections.
