Battery Design: The construction and quality of the battery components also play a role. Poorly designed or manufactured batteries may experience voltage irregularities. Age of the Battery: Over time, batteries naturally degrade. An older battery will typically have a lower voltage due to reduced chemical efficacy.
The voltage and current of a battery are two critical factors that affect its capacity. The capacity of a battery is typically measured in amp-hours (Ah), which is a unit of electrical charge. The higher the voltage and current of a battery, the more energy it can store and the longer it can last before needing to be recharged.
In this example, we will consider a 7S lithium-ion battery running a 24-volt AC inverter. A 7S lithium-ion battery has a fully charged voltage of 29.4 volts and a dead voltage of about 18.5 volts. Drawing a 1100W load from the battery pack will require around 37 amps when the battery is fully charged. 1100 watts ÷ 29.4 volts = 37.4 Amps

Let''s take a very standard deep cycle battery that has a 100 A.H. rating. A.H. stands for amp-hour rating. A.H. stands for amp hour and a battery that has 100 Amp hour capacity has a spec or listing as a 100 amp hour rated battery. This means the battery over the course of one hour can discharge or supply 100 amps.
Max Discharge Current (7 Min.) = 7.5 A; Max Short-Duration Discharge Current (10 Sec.) = 25.0 A; This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.

$begingroup$ You should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is mentioned is 1000 mA = 1 A. That does not mean you cannot discharge with 2 A but realize that the battery''s capacity will be less at such a high current.

To help you understand, an example is a 15 amp swamp cooler will run safely for 5 hours with a 180 AH, rated at 20 Hours, with an AGM battery. For a little more detail on the math check out our Math Behind the Magic article.
maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
A 12-volt deep cycle battery has 6 individual cells, and thus each cell holds approximately 2 volts. Interestingly, a fully charged 2-volt cell has a voltage of approximately 2.15 volts while a fully discharged 2 volt cell has a voltage of 1.9 volts.
C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to load 100 …

A LiPo battery should be charged at a maximum rate of 1C, where ''C'' is the capacity of the battery in amp hours divided by hours - so a 2200mAh battery can be safely charged at 2200mA (i.e. 2.2A.) For some high performance batteries the manufacturer may also state a charge C rating above 1C (such as some Turnigy Graphene batteries), but if this ...
Firstly, we want to look at the nominal system voltage. This will tell us what voltage battery banks the controller is compatible with. In this case, you can use 12V or 24V battery banks. Anything higher, such as a 48V battery bank, the controller will not be able to work on. Secondly, we look at the rated battery current.
A battery is an electrochemical device which generates a voltage potential when placing metals of various affinities in an acid solution. For example, a battery that has an actual voltage of 1.62 V but commonly it is referred to as a "1.5-volt battery", which means that the battery has a nominal voltage of 1.5 V.
