The LiFePO4 Forklift Battery F36690A typically features an 80V nominal voltage and 230Ah capacity, delivering 18.4kWh energy storage for industrial electric forklifts. Designed for heavy-duty applications, it uses prismatic LiFePO4 cells with a built-in BMS for thermal management and safety. These batteries generally support CC-CV charging protocols up to 88-91V (for full charge) and offer a lifespan exceeding 4,000 cycles at 80% DoD. Common certifications include CE and UN38.3, with a standard 3-year warranty covering manufacturing defects.
How Much Does a Forklift Battery Weigh?
What voltage range does F36690A operate within?
The F36690A operates at a nominal 80V with operational range spanning 70V (discharged) to 91V (fully charged). LiFePO4 chemistry enables stable voltage output even under 230A peak loads typical in forklift lifting operations. Pro Tip: Never let cell voltages drop below 2.5V – irreversible capacity loss occurs below this threshold.

These batteries maintain ±2% voltage consistency across cells thanks to active balancing in the BMS. For example, when powering a 5-ton forklift, the system delivers 65-80V during normal operation, dropping to 70V only during maximum hoist acceleration. Transitioning between charge/discharge states, the voltage stabilizes within milliseconds due to low internal resistance (<15mΩ).
What cycle life can operators expect?
The F36690A achieves 4,000+ cycles at 80% depth of discharge (DoD) when maintained between -20°C to 45°C. Partial cycling (30% DoD) extends lifespan beyond 8,000 cycles, outperforming lead-acid alternatives 3:1. Real-world example: Daily 2-shift warehouse operations typically consume 60% capacity, enabling 6+ years of service before reaching 80% original capacity.

How does charging differ from lead-acid systems?
LiFePO4 forklift batteries require constant current-constant voltage (CC-CV) chargers instead of lead-acid’s bulk/absorption phases. The F36690A typically charges at 0.5C (115A) up to 88V, then maintains voltage until current drops to 5A. This method prevents gassing and completes charges 40% faster than equivalent lead-acid systems.
Unlike lead-acid batteries needing weekly equalization charges, LiFePO4 systems maintain cell balance automatically through the BMS. Practically speaking, operators can implement opportunity charging during lunch breaks without capacity penalties – a game-changer for 24/7 operations.
What safety features are incorporated?
The F36690A integrates 5-layer protection: over-voltage, under-voltage, over-current, short-circuit, and temperature monitoring (-30°C to 75°C). The explosion-proof prismatic cells utilize ceramic-separator technology that shuts down ion flow at 150°C, while the IP67-rated steel enclosure contains thermal events.
| Feature | LiFePO4 | Lead-Acid |
|---|---|---|
| Thermal Runaway Temp | 270°C | N/A |
| Ventilation Required | No | Yes |
| Spill Risk | None | High |
What physical dimensions are typical?
Standard F36690A units measure approximately 800×600×400mm (L×W×H) weighing 540kg ±3%. The compact design enables 15% better space utilization compared to equivalent lead-acid batteries. Pro Tip: Always verify forklift compartment dimensions – some legacy models require spacer kits for proper fitment.
Transitioning from lead-acid? You’ll gain 300-400mm vertical clearance in most battery compartments. For example, a Crown SC 6000 series forklift can reduce battery change time from 15 minutes to under 5 minutes due to the LiFePO4’s integrated lifting lugs and reduced mass.

FAQs
Yes, but require voltage-compatible chargers and often need spacer kits for secure fitment in legacy battery compartments.
How often should cell balancing occur?
The BMS automatically balances cells during charging cycles, typically requiring no manual intervention for 3-5 years under normal use.
What maintenance is required?
Quarterly terminal cleaning and annual capacity verification tests. Unlike lead-acid, no watering or equalization charges are needed.
