What is a lead acid battery?
A chemical element, the principal constituent of a lead acid battery. Chemical formula Pb, atomic number 82. A metal alloy commonly used in battery castings or plates. A lead base alloy sometimes used for battery components in place of antimonial lead alloys.
How do you calculate the capacity of a lead-acid battery?
To calculate the capacity of a lead-acid battery, you need to know its reserve capacity (RC) and voltage. The reserve capacity is the number of minutes a fully charged battery can deliver a constant current of 25 amps at 80°F until its voltage drops below 10.5 volts. The formula for determining the capacity of a lead-acid battery is:
How do you test a lead-acid battery?
The most reliable method for measuring the remaining capacity of a lead-acid battery is through a full charge and discharge cycle. This process involves charging the battery to its full capacity, and then discharging it completely while measuring the amount of energy it produces.
How to choose a lead-acid battery?
Hence when choosing a battery, it is important to keep in mind a general rule: whatever the calculated power capacity of a lead-acid battery is, halve it to get the actual usable capacity. This is because, in general, you can only use a maximum of half the total capacity of a lead-acid battery before needing to charge it back up again.
How many cells are in a 12 volt lead acid battery?
There are six cells to a 12 volt lead acid battery. A battery cell’s maximum ability to deliver current (amps). The positive plates contain a maximum amount of lead oxide and a minimum of lead sulphate and the negative plates contain a maximum of sponge lead and a minimum of sulphate. The electrolyte is at maximum specific gravity.
