6 FAQs about [How to read the rated current of the battery]

What is a battery rating?

Batteries are made up of a group of cells where a cell is the smallest individual electrochemical unit. These cells are connected in series, in parallel, or in a combination of both in order to obtain the required voltage and capacity. A typical battery rating consists of the following terminologies: 1. Nominal Voltage

What is a good charge current for a battery?

(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.

How do you calculate a battery rated capacity (SoC)?

Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate. SOC is defined as the remaining capacity of a battery and it is affected by its operating conditions such as load current and temperature. It is calculated as: SOC = Remaining Capacity Rated Capacity

How do you calculate watt-hours in a battery?

Energy Capacity (Watt-Hours) is calculated by multiplying the voltage by the amp-hours (Ah) rating. It provides a measure of the total energy stored in the battery. For instance, a battery with 12 volts and 100 Ah has an energy capacity of 1200 watt-hours. Understanding watt-hours helps evaluate how long a battery can power a specific device.

What happens if a battery discharge current is 100 Ma?

With a higher discharge current, of 100 mA, the capacity falls to 1.15 Ah. By increasing the discharge current by 100, the overall capacity of the battery has fallen by nearly 66%. So if your device needs 35 mA to function and your cut-off voltage is 3 V, your maximum capacity will be 1.5 Ah and you will lose what is left of the battery’s capacity.

How do I know if a battery is right for me?

Batteries come in all sorts of shapes and chemistries and not all batteries will be fit for purpose. One way you can find out if a battery matches your application’s profile is by carefully reviewing the datasheet against your design requirements. How much energy does my device consume?
