Frequently Asked Questions
What is the cycle life of the 80V 840Ah forklift battery?
At 80% depth of discharge (DOD), the cycle life exceeds 4000 cycles, significantly longer than traditional lead-acid batteries (1000-1500 cycles). This provides years of service under normal use conditions, substantially reducing battery replacement costs.
How long does it take to fully charge the battery?
With fast charging technology and a compatible 80V charger, the battery reaches 80% charge in 1 hour and full charge in 2 hours. It supports opportunity charging, allowing flexible charging during breaks without waiting for full discharge.
Is the battery maintenance-free?
Yes, completely maintenance-free. No watering, equalization charging, acid handling, or electrolyte level inspections required. Only normal charging is needed during use, significantly reducing operational and maintenance costs.
What safety protection functions does the battery have?
Equipped with smart dual BMS battery management systems providing comprehensive protection: overcharge, overdischarge, overcurrent, short circuit, high/low temperature, and reverse polarity protection. LiFePO4 cells offer excellent thermal stability with no fire or explosion risks.
Can this battery directly replace my existing forklift's lead-acid battery?
Yes. Designed to standard 80V forklift battery dimensions, it directly adapts to most 80V electric forklifts (Toyota, Linde, Jungheinrich, Crown, KION, etc.) without battery compartment or circuit modifications. Custom sizes available for special requirements.
What is the warranty period and coverage?
6-year warranty covering cell quality, BMS system failures, and battery shell damage (non-human factors). Includes free repair or replacement services with 24-hour technical support and global after-sales network.
Can the battery operate in low-temperature environments?
Yes. The battery discharges stably from -20°C to 60°C, suitable for cold storage and outdoor winter conditions. Charging range is 0°C to 55°C, with slightly reduced efficiency in extreme cold that doesn't affect overall performance.
