How To Calculate Battery Charging Time

How To Calculate Battery Charging Time

To calculate a battery's charging time, you can use the following formulas: 

• Battery capacity and charge current

Divide the battery's capacity by the charge current. For example, if a battery has a capacity of 1200mAh and a charger output current of 600mA, the charge time is 1200mAh/600mA*1.2, or 2.4 hours. 

• Battery capacity, depth of discharge, charge current, and charge efficiency

Divide the product of the battery's capacity and depth of discharge by the product of the charge current and charge efficiency. 

• Load power and battery power

Divide the load power by 1,000 to get the value in kilowatts, then divide the battery's power by that value. For example, if the load power is 3,680 W, which is 3.7 kilowatts, and the battery power is 24 kW, the charging time is 24 kW/3.7 kW, or 6.5 hours. 

• Electric vehicle (EV) charging time

Divide the amount of charge needed by the power provided by the charger. For example, if an EV has an 80 kWh battery and needs to charge from 20% to 80%, the charge needed is 48 kWh (80 kWh x 0.6). If the charger has a power of 7.68 kW, the charging time is 48 kWh/7.68 kW, or about 6.25 hours. 

Lento Batteries is Saudi Arabia  leading and best tubular inverter battery manufacturer. We are the best battery suppliers in Saudi Arabia 2024 . The Lento Research and Development team is constantly looking for ways to improve and increase the reliability of inverter batteries.

This can be accomplished by producing batteries with consistent high performance. Our inverter battery requires less maintenance and takes up little space.

Instead of pasting the active material on the plate's surface, a tubular battery uses technology that seals it in polyester tubes called gauntlets. As a result, no shedding or corrosion occurs, resulting in a long battery life. Tubular batteries, due to their toughness and durability, can operate at extreme temperatures and are used in high cyclic applications involving frequent and prolonged power outages.

Lento uses premium technology and high-grade materials in these lead acid tubular batteries to deliver maximum power for extended durations and have an appreciably longer life span. These batteries are specifically suitable for powering up UPS and inverters. Lento flooded lead acid batteries are environment-friendly, highly reliable in performance and are low in cost. Here again our extensive research and development wing has helped us create batteries customized to suit Indian operating conditions. These flooded batteries are perfect for use in battery powered vehicles and to power inverters as well as for telecom use.

Inverter Battery Types

The average life or the lifespan of an inverter battery depends on its type, among other important features.

Each type of inverter battery has its average lifespan. Here are the 3 common types of inverter batteries in Nigeria.

1. Flat Plate Inverter Battery
2. Tubular Inverter Battery
3. Gel Inverter Battery

Let's look at the different types of batteries on the market and pick the one that best meets your needs:

1. Flat plate battery-These inverter batteries are lead-acid batteries that are recommended for areas with frequent but short-term power outages.
2. Tubular Battery- A tubular battery is a lead-acid battery that is larger in size than a flat plate battery. These best inverter batteries are ideal for areas with long and frequent power outages, such as tier 2 or tier 3 cities or city outskirts.
3. Gel Batteries- Gel batteries provide more consistent power backup over a longer period of time than standard lead-acid batteries because they contain a special crisscross structure of gel that holds the acid and prevents it from settling down. They also provide greater power backup per cycle.

Which Inverter Battery Is the Best?

So far, the best tubular inverter battery in Nigeria. Some may argue that it necessitates a Distilled water refill at regular intervals, but it is still worthwhile.

A tubular inverter battery can power devices that require a lot of power. They are also more robust and long-lasting. Above all, they have the longest average lifespan (7 to 8 years).

What Are the Benefits of a Tubular Inverter Battery?

There are numerous benefits to purchasing a tubular inverter battery in Nigeria. Here are a few examples.

1. A tubular battery is capable of charging and discharging at relatively high temperatures.
2. They can withstand continuous material shedding for an extended period of time.
3. Tubular batteries can be used with devices and equipment that require a lot of power.
4. Even though tubular batteries require maintenance, they are more convenient to use.
5. Unlike gel batteries, tubular batteries can be charged at high voltages.
6. They are also an excellent choice for areas with short periods of grid power.
7. To top it all off, tubular batteries have the longest life span. They have a lifespan of up to 8 years.

FAQ- 

What is the formula for charging A battery?

Battery Charging Current and Battery Charging Time formula

charging current should be 10% of the Ah rating of battery. so charging current for120Ah Battery = 120 x (10/100) = 12 Amperes. but due to losses, we can take 12-14Amperes for charging purpose.

How do you calculate battery power time?

The calculator applies the formula: Capacity (Ah) x Voltage (V) x Efficiency / Load Power (W). This equation gives an estimated runtime based on the input values. For instance, a 100 Ah battery at 12V with 90% efficiency powering a 50W load would have a runtime of (100 Ah x 12V x 0.9) / 50W = 21.6 hours.

How do you solve charging time?

How to calculate charging time yourself?

1. Divide the load power by 1,000 for a value in kilowatts. ...
2. Divide the power of your battery (also in kW) by the figure obtained to get the charging time. ...
3. First calculate your load power (P), by multiplying the voltage (U in volts) by the current (I, in amps).

How long does it take to charge A 200Ah battery?

100 % charge of 200 Ah with 2 A current will take 100 hours or about 4 days. With 12 A 16.67 hours will be needed. The battery should be full charged before the next power outage.

How to calculate charging time?

Example: Suppose the battery capacity is 200Ah, and the charging current is 20 amps. In this case, the battery charge time will be: Charge Time = 200Ah ÷ 20A = 10H.

How do you calculate charge formula?

It is measured in coulombs (C) and can be calculated using the formula, Charge (C) = Current (A) x Time (s). →How do I calculate the current in a circuit? To calculate the current in a circuit, you need to know the voltage (V) and the resistance (R) of the circuit.

How do you measure battery time?

Battery life = Capacity / Consumption × (1 - Discharge safety) , where: Capacity – Capacity of your battery, measured in ampere-hours – you can usually find this value printed on your battery (or use our battery capacity calculator); Consumption – Average current draw of your electronic device, expressed in amperes.

How do you calculate how long a battery charge will last?

To find battery lifetime, divide the battery capacity by the average device current consumption over time. You can then break it down into where: The average is the sum of the amount of current consumed when collecting data, scaled by the ratio of time that the device is collecting data.

Can a 1000W inverter charge a 200Ah battery?

Therefore, it is more efficient and practical to use a suitable battery charger directly. In summary, a 1000W power inverter cannot directly charge a 200Ah battery by itself, but it can be used as part of a power system to charge the battery with a suitable charger.
