Differentiating Between a Car Battery and a Deep Cycle Battery

Lead acid vs Deep Cycle batteries

People who own or operate Recreational Vehicles, boats and solar power systems know about deep cycle batteries. They are mainly used to power golf carts, and to store solar power in large solar systems. You see, solar power is produced by the sun during the day and stored by the deep cycle solar battery for use at night. A lot of people think that deep cycle batteries and normal lead-acid car batteries can be used in place of each other. While they use the same chemistry to operate, they have pertinent differences in how they optimize the use of their parts.

Main Difference between the two batteries

The main difference between the deep cycle batteries and the lead-acid car batteries is the amount of current passed over a certain period of time. The car battery is designed to produce a lot of current for a short period of time. However, the deep cycle battery can produce a steady amount of current over a long period of time. A car battery works by providing one big spurt of power to start the car, after which the alternator provides all the additional power that the car needs. In fact, a car battery can last all its lifetime without ever losing more than 20% of its power. This means that they can last a really long time if well used.

The deep cycle battery, on the other hand, can provide a power surge but not as much as a car battery can. It is designed to be recharged constantly because it discharges quickly and regularly. This would definitely damage a car battery. Because of this major difference, car batteries have thin plates while deep cycle batteries use thick plates for their charging and discharging purposes.
