Service Life of Batteries for Electric Scissor Lifts (General Industry Standards)

I. Maintenance-Free Lead-Acid Batteries (Standard Configuration for Domestic Equipment, Low Cost)

1. Cycle Life
   300–700 charge-discharge cycles

• Conventional flooded lead-acid batteries: 300–500 cycles
• AGM gel maintenance-free batteries: 500–700 cycles

1. Actual Service Life (1 full charge-discharge cycle per day)

• Proper maintenance without deep discharge: 2–3 years
• Heavy-duty construction site use, frequent full depletion, or outdoor low-temperature operation: Full battery pack replacement required after 1.5–2 years

1. Replacement Criteria
   Replacement is mandatory if:

• Continuous operating time after full charge drops to less than 60% of the original new unit performance;
• Excessive voltage difference between individual batteries;
• Case bulging or electrolyte leakage occurs.

II. Lithium Iron Phosphate (LiFePO4) Batteries (Optional for Lithium-Powered Scissor Lifts, Preferred for Export & High-Frequency Rental)

1. Cycle Life 2,000–3,000 cycles for industrial-grade lithium batteries (standard at 80% remaining capacity)
2. Actual Service Life

• Single-shift daily regular operation: 5–8 years. Major branded lithium batteries come with a 5-year warranty and a designed service life of 8 years.
• Double/triple-shift high-frequency rental scenarios: Minimum service life of 4–6 years
• Advantages: Maintenance-free, tolerant to mild shallow discharge, far less capacity degradation in low temperatures compared to lead-acid batteries.

III. Continuous Operating Duration on a Full Single Charge (Range, Distinguished from Total Service Life)

• Light-duty indoor maintenance work: 6–8 hours of continuous operation when fully charged
• Frequent lifting/lowering and full-load driving on construction sites: 4–6 hours
• Cold winter conditions (below -5°C): Lead-acid battery runtime drops by approximately 30%, while lithium batteries suffer far milder capacity loss.

IV. Key Factors That Significantly Shorten Battery Lifespan

1. Deep full discharge: Draining batteries completely each time. One severe deep discharge can cut a lead-acid battery’s service life by half a year.
2. Long-term idle storage without supplementary charging: Lead plates will sulfide and fail if stored for over one month without recharging.
3. Low-quality chargers, overcharging, or charging under direct high-temperature sunlight.
4. Neglected water refilling for flooded lead-acid batteries, corroded or overheated terminal lugs.
5. Long-term outdoor operation in frigid environments.
