Technical Specifications:

• Voltage: 6 V
• Capacity: 4 Ah
• Dimensions:
  • Length: 70 mm
  • Width: 48 mm
  • Height: 100 mm
  • Total height (with terminals): 106 mm
• Weight: 0.65 kg

For safe discharge and to extend the battery's lifespan, the final discharge voltage should not drop below the following values:

• For discharge current up to 0.1 * battery capacity (A): minimum 1.75 V
• For discharge current between (0.11 ... 0.2) * battery capacity (A): minimum 1.70 V
• For discharge current between (0.21 ... 0.3) * battery capacity (A): minimum 1.67 V
• For discharge current between (0.31 ... 1) * battery capacity (A): minimum 1.60 V
• For discharge current above 1.1 * battery capacity (A): minimum 1.3 V

Moreover, proper charging will extend the battery's lifespan. Accurate monitoring of the charging voltage is essential:

• Standby and float mode: 2.25 and 2.3 V/cell, at 25 °C
• Cyclic operation: 2.35 and 2.45 V/cell, at 25 °C

The recommended initial current is a maximum of 0.3 * battery capacity (A). The charging voltage should be adjusted for temperature: it should be slightly increased at low temperatures (winter) and decreased at high temperatures (summer) (+/- 3 mV/degree Celsius/cell in standby mode or +/- 4 mV/degree Celsius/cell in cyclic mode).

Internal resistance (fully charged battery, at 25 °C): 28 mOhm

The effect of temperature on battery capacity:

• At + 40 °C: 102%
• At + 25 °C: 100%
• At 0 °C: 85%
• At -15 °C: 62%

Self-discharge (at 25 °C):

• Capacity after 3 months of storage: 91%
• Capacity after 6 months of storage: 82%
• Capacity after 9 months of storage: 64%

Packaging: 20 pcs./box
