Example: 150,000 / 3,600 = 41.67. A battery with higher reserve capacity minutes makes your chances slim of running out of power even if your alternator fails. After sometime when the vehicle reaches optimum condition, alternator reliefs battery of its duty to take charge of vehicles all electrical power requirements. Posted on February 23, 2018 September 14, 2018 by Michelle Cochrane. Amp Hour shows the amount of energy that can be stored in the battery. Battery capacity is a measure (typically in Amp-hr) of the charge stored by the battery. Ryan Menezes is a professional writer and blogger. Else you should go for a better reserve capacity rating. Though AH and RC do the same trick of displaying battery capacity, there is a big difference between them. Multiply the reserve capacity by 60 to convert it to seconds. You may think that calculating how long a battery will last at a given rate of discharge is as simple as amp-hours: for given capacity C and discharge current I time will be, However, battery capacity decreases as the rate of discharge increases. CCA exhibits the load a fully charged battery can generate for a 30 seconds time period in 0-degree Fahrenheit.

In order to get the estimate for the Ampere-hours we need to convert this value to hours by dividing by 60 minutes then multiply by the 25 Amperes.

Among them, reserve capacity is one of the essential elements that give out an idea of a battery’s capability. These ratings are not very similar so there is no way to make a precise conversion from one unit to another. Multiply this length of time by 25, which is the battery's amperage. Of course the proper way to find an equivalent battery would be to examine the datasheets of each battery and particularly the discharge characteristics curves. An ampere is a … This means if you click on the link and purchase the item, we will receive an affiliate commission at no extra cost for you. However, in hotter climate areas, good CCA numbers will not help you much compared to a good all day running battery having higher reserve capacity. Recent developments in measuring battery condition resulted in an instrument called Cadex CA-12. For example, if a battery offers a 100-minute capacity: 100 x 60 = 6,000 seconds. A battery’s functioning is a complex concept that depends on a few factors. Among them, reserve capacity is one of the essential elements that give out an idea of a battery’s capability. What is Battery Reserve Capacity – Trolling Battery Guy, If you ever check out a deep cycle battery, then you have come across a rating named reserve capacity. Reserve capacity is known as the amount of time a fully charged 12V battery at 80 F can supply 25 amperes at 10.5 volts until the voltage drops down. more conveniently we can combine 60 and 25 in one constant by dividing 25/60 and getting the 0.4167 value that keeps appearing at battery sites. All these talks are for you to realize how important a battery can be. 2019 Trolling Battery Guy. Note that there are battery run-time calculators on the web that are very wrong. Having access to these pieces of information gives drivers and sailors a better way of understanding the time to get a new battery. Then the alternator steps up to power the engine while the battery still powers stereo, lights and other electrical equipment at the same energy. All rights reserved.

The reserve capacity of a battery is the number of minutes for which it can run at 25 amps of current without its voltage dropping below 10.5 volts. Battery capacity formula. Consider a battery rated at 12 RCM. Reserve Capacity To Ampere-hours conversion. If you are living in a colder climate area, then you should get a battery having higher, Difference Between Amp Hours and Reserve Capacity, Recent developments in measuring battery condition resulted in an instrument called, How to Charge a Deep Cycle Battery Properly, 5 Step To Deep Cycle Battery Charging Instructions, How to Charge a Boat Battery on the Water. Since watts = amps * volts divide the watt hours by the voltage of the battery to get amp-hours of battery storage Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.

It is a unit of electric charge. It roughly describes the amount of energy the battery effectively stores and technically specifies the battery's charge capacity. So you should have a proper sense of it if you are planning to buy a good deep cycle trolling motor battery. Amp hours (AH) may be presented on your battery as 200AH @ 25 HR, which means that the battery would provide a constant supply of usable current for 25 hours at a rate of 8 amps. This rating is a crucial parameter to judge batteries, especially deep cycle batteries. Ampere-hours = 0.4167* (Reserve Capacity) Here is a handy table displaying approximate Ampere-hours for Reserve Capacity from 1 to 10 minutes Of course the proper way to find an equivalent battery would be to examine the datasheets of each battery and particularly the discharge characteristics curves. h) by EN 60095-1 is rated at a fixed discharge current of I/20, within 20 hours until final discharge voltage of 10.5 V at 25 °C is reached. If you are living in a colder climate area, then you should get a battery having higher CCA numbers. This is the number of coulombs of charge in the battery.

When you start your vehicle, your battery generates 25 amps at 10.5 volts to run the alternator. Multiply this length of time by 25, which is the battery's amperage. He is also a member of Mensa and the American Parliamentary Debate Association. This is the number of amp-hours in the battery. The following formula us used to calculate a battery capacity in amp-hours: E = V * Q Where E is the energy stored in the batter in watt-hours V is the voltage of the battery As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:. An ampere hour (abbreviated Ah, or sometimes amp hour) is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour. Divide this answer by 3,600, which is the number of coulombs in an amp-hour.
