Golf Cart Lead-Acid Batteries

• Prohibited: Start charging <20% SOC

• Recommended: Charge fully once SOC 20%–30%; minimize charging frequency

• Caution: Avoid charging at 40%–50% SOC; no undercharge (must reach 100%); no overcharge

Key Logic

1. Over-discharge risk: <20% SOC → rapid lead sulfate crystallization → irreversible capacity loss

2. Cycle life limit: Lifespan = number of "discharge-full charge" cycles; fewer charges = longer life

3. Dual harm: Undercharge accelerates sulfation; overcharge causes electrolyte boiling (water loss) & plate deformation → rapid failure
