Product Charging Guidelines | Ni-Fe Industrial Batteries

For optimal performance & longevity in railway signal, emergency communication & industrial automation applications

🔋 Initial Activation (For Batteries Stored > 6 Months)

Charge at 0.2C₅A → 12 hours
Discharge at 0.2C₅A → 1V/cell cutoff
Repeat 3–5 cycles
Qualification Check: Discharge duration ≥ 5 hours + voltage ≥ 1V/cell → Switch to normal charging for operation

📊 What is C₅ (Nominal Capacity)?

Standard capacity measured at 20℃: 5-hour discharge rate to 1.0V/cell cutoff → Battery’s rated capacity
