Theoretically, it can be thought of as the total number of amps that the battery can deliver over the period of one hour, although in practice the meaning of amp-hours is a little more complex. A 1200W toaster will only use 5A in a 240V system but will use 100A in a 12V system! Amp-hours (Ah)Īmp-hours (Ah) is the most common calculation used to state the capacity of a battery. This is important to note when determining whether a particular appliance (whose power draw is commonly measured in watts) can be used in a 12V system. In a 12V system, more electricity is used (measured in amps) to provide a given wattage compared to a 240V system. In this analogy, volts represents the water pressure and amps represents the flow rate. These terms can be confusing to understand, but a handy analogy to use is that of a garden hose. Watts is a measure of total system power, and is calculated by multiplying Volts and Amps. Voltage (V) is a measure of the force with which an electrical current is flowing through an electrical line, whereas amperage measures how much electrical energy is being supplied through the line. The three most common terms associated with electrical devices such as batteries are voltage (volts / V), amperage (amps / A) and wattage (watts / W). Common Termsīatteries are highly technical products, and the terms used to describe their various features and operation can get confusing. Physically, the main difference between deep cycle and starter batteries is that deep cycle batteries have thicker battery plates and denser active paste material, allowing them to withstand the deeper charge cycles, whereas starter batteries have thinner plates and less dense active material to maximise surface area, allowing them to deliver higher starting power. They are unable to provide the high-current burst that a crank battery can, but they can provide continuous power for much longer periods of time. They are not suitable for providing sustained power on a regular basis.ĭeep cycle batteries, on the other hand, are designed to be deeply discharged without harming the battery, hence the name. Generally, only a small portion of the battery’s total capacity is ever used, and this is quickly restored by the alternator. Normal 12V batteries, often called start batteries or crank batteries, are designed primarily to provide a short, high-current burst of power, for example to turn over a vehicle engine. What is a Deep Cycle Battery? How Do They Differ from Normal 12V Batteries? This guide aims to explain in plain English everything you need to know to confidently purchase your next 12V battery. With campsites becoming increasingly reliant on electrical power, it is important to ensure that you are selecting the right deep cycle batteries for your application and that you understand their strengths and weaknesses. ![]()
