For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.

How long does a lead acid battery last?

Conductance, i.e., the reciprocal of internal resistance, which is expressed as mho or Siemens, has some kind of positive proportionate relationship with the battery capacity. 3 ~ 5 years under 2.3Vpc and 20°C floating charge condition. 3 ~ 5 years under 2.3Vpc and 20°C floating charge condition. 4. Operation of sealed lead acid batteries

What is a good coloumbic efficiency for a lead acid battery?

Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.

How many Watts Does a lead-acid battery use?

This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.

What happens when a lead acid battery is discharged?

When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
