Discharge rate of lead-acid solar container battery

4 FAQs about [Discharge rate of lead-acid solar container battery]

What is a solar battery discharge curve for a 24V lead acid battery?

Solar battery discharge curve for a 24V lead acid battery The followings could be observed from the above graph: Range between 80% to 100% yields above rated output voltage, but the voltage drops quickly. The battery could be charged up to 100% if the load requires a voltage boost for a short amount of time.

Why is recharging a lead-acid battery important?

The loss in capacity is particularly severe at high current rates of discharge and low temperature. At high temperatures, the gain in capacity is highest at the highest current rates of discharge. Proper recharging between discharges is an important key to obtaining optimum life from any lead-acid battery.

What is the output voltage of a 24V lead acid battery?

For the 24V lead acid battery example shown in figure 1, a battery which is 100% charged will have an output voltage of around 25.6 volts. At 50% charged stage, the output voltage of the battery is around 24V. Once the battery is 30% discharged, the discharge rate of the battery picks up sharply to a complete discharge.

What is the capacity of a lead-acid battery?

Ordinary lead-acid (0.1C): Min. capacity = 1000Ah Lead-carbon (0.25C): Min. capacity = 400Ah Discharging Current (Load-dependent): *10kW load + 48V battery* → Max discharge current = 200A Lead-carbon battery(30I₁₀): Min. capacity = >80Ah Gel battery (3I₁₀): Min. capacity = 800Ah 3. Depth of Discharge (DOD) & Cycle Life: Shallow Cycle: 10-30% DOD
