Battery Reserve Capacity Calculator

Battery Reserve Capacity Calculator. Knowing the hour rate of your battery, its. The reserve capacity is the amount of time that a battery can run at 25 amps until its voltage drops to 10.5 volts.

This means that at 25 degrees celcius, the battery can supply 25 amps for 160 minutes before the voltage drops. This rating is a crucial parameter to judge batteries, especially deep cycle batteries. 0.7 = battery cycle life considerations (run time) note:

How To Calculate Reserve Capacity For Battery


So multiply the number of minutes by 25a (and divide by 60) and you have a measure of ah (@25a). A 1c (or c/1) discharge drains the battery at that same rate. A reserve capacity rating tells you the reserve capacity of a battery.

A 1C (Or C/1) Charge Loads A Battery That Is Rated At, Say, 1000 Ah At 1000 A During One Hour, So At The End Of The Hour The Battery Reach A Capacity Of 1000 Ah;


18.33 ah * 12 volts = 220.96 watt hours / 1000 =.22 kwh. I is current in ampere. Gel flooded (lead acid) agm (sealed lead acid) all others.

T Is The Duration In Hours.


A discharge of 1c draws a current equal to the rated capacity. The same battery discharged at 0.5c provides 500ma for two hours. They are typically rated for a discharge rate over 20 hours.

Knowing The Hour Rate Of Your Battery, Its.


However, batteries will age over time and lose some of. Let’s discuss a case for better understanding. (15.7 ampere hours x 2.5 days = 41 ampere hours) of battery with reserve calculated.

It Identifies How Many Minutes The Battery Can Deliver A Constant Current Of 25 Amps At 80°F Without Falling Below The Minimum Voltage, 1.75 Volts Per Cell, Needed To Keep.


Load current = consumption of device in amperes. Reserve capacity = 2.4 x amp hours (the 2.4 comes from 60 minutes in an hour divided by 25 amps, 60/25 = 2.4) below you can convert reserve capacity (in minutes) to amp hours and vice versa: Reserve capacity is measured in minutes.
