Speaker 1: Brain with today's question, what is the difference between a
Speaker 1: normal lead acid car battery and a deep cycle battery?
Speaker 1: People who have recreational vehicles and boats are familiar with
Speaker 1: deep cycle batteries. These batteries are also common in golf
Speaker 1: carts and large solar power systems, where the sun produces
Speaker 1: power during the day and the batteries store some of
Speaker 1: that power for use at night. Both car batteries and
Speaker 1: deep cycle batteries are lead acid batteries that use exactly
Speaker 1: the same chemistry for their operation, and the differences in
Speaker 1: the way the batteries optimize their design. A car's battery
Speaker 1: is designed to provide a very large amount of current
Speaker 1: for a short period of time. This surge of current
Speaker 1: is needed to turn the engine over during starting. Once
Speaker 1: the engine starts, the alternator provides all the power that
Speaker 1: the car needs, so the car battery may go through
Speaker 1: its entire life without ever being drained more than or
Speaker 1: so of its total capacity. Used. In this way, a
Speaker 1: car battery can last a number of years. To achieve
Speaker 1: a large amount of current, a car battery uses thin
Speaker 1: plates in order to increase the surface area. A deep
Speaker 1: cycle battery is designed to provide a steady amount of
Speaker 1: current over a long period of time. A deep cycle
Speaker 1: battery can provide a surge when needed, but nothing like
Speaker 1: the surge a car battery can. A deep cycle battery
Speaker 1: is also designed to be deeply discharged over and over again,
Speaker 1: something that would ruin a car battery very quickly. To
Speaker 1: accomplish this, a deep psycle battery uses thicker plates. A
Speaker 1: car battery typically has two ratings, the cold cranking amps,
Speaker 1: which are the number of amps that the battery can
Speaker 1: produce at thirty two degrees fahrenheit for thirty seconds, and
Speaker 1: the reserve capacity, the number of minutes that the battery
Speaker 1: can deliver twenty five amps while keeping its voltage above
Speaker 1: ten and a half volts. Typically, a deep psychle battery
Speaker 1: will have two or three times the reserve capacity of
Speaker 1: a car battery, but will deliver one half the cold
Speaker 1: cranking apps. In addition, a deep cycle battery can withstand
Speaker 1: several hundreds total discharge and rescharge cycles, while a car
Speaker 1: battery is not designed to ever be totally discharged. For
Speaker 1: more on this and thousands of other topics. Is it
