Car Batteries VS Deep Cycle Batteries

Car batteries are specially designed to provide a short, sharp burst of power in order to crank over and start the vehicle’s engine. 

Only a relatively small portion of the battery’s capacity is used and this is restored by the vehicle’s alternator. Car batteries have thinner lead grids and active material to maximise plate surface area, delivering greater starting power. However they are not suitable for providing long periods of power.

Deep Cycle batteries are constructed using thicker battery plates and a denser active material, to withstand repeated charge and discharge cycles. 

Rather than providing high bursts of power for short periods of time, they are specially designed to deliver sustained power with lower current draw over extended periods of time. Repeated cycling does not cause the same level of damage that a car battery would sustain during the same usage.
