Fully Charged Battery

Introduction

The most important component of your car is the battery. Even if your car is made by a renowned company, is well-maintained, has a full tank of petrol, and is equipped with brand-new tyres, you won't be able to move if your battery is dead.Even though the majority of automobile lead-acid batteries are generally considered to be "maintenance free," there are still things you can do to make them last longer.

There are a few simple things you can do at home to increase the lifespan of your battery. To maintain optimal performance, the following elements should typically be inspected once a month, or at least every three months.

Charging

The circuitry used to recharge the batteries in portable products, including mobile phones, is crucial in determining the battery life and everyday usability of the product.

The size and kind of the battery being charged determines the charging process (how much voltage or current to use, for how long, and what to do when charging is finished).

Depending on the stage of charging the battery has reached, contemporary battery chargers dynamically adjust the charging conditions. Without any safety concern, a dead battery can be charged more quickly. This is the reason why the majority of benchmarks for charging speed, including ours, mention the battery charging level attained following a 30-minute charging session on an empty battery.

Any charging speed greater than basic chargers' 5V/1A output, which equates to 5W of electricity, is referred to as quick or fast charging.

Fully Charged Battery Voltage

Any voltage over 2.15 volts per cell, which is the voltage of the fundamental chemistry, will charge a lead acid battery. This also implies that no charging will take place at less than 2.15 volts per cell (12.9V for a "12V" battery) However, because the battery can withstand larger currents, a higher voltage is typically used in order to speed up the charging response. At the lowest voltage, charging will take more than 200 hours to complete. The charging time would be between 85 and 120 hours at 2.25V per cell (13.5). The voltage to avoid as you raise the voltage to get faster charging is the gassing voltage, which places a cap on how high the voltage can go before unfavourable chemical reactions occur. Between 2.15V per cell (12.9V for a "12V" 6 cell battery) and 2.35V per cell are the charging voltages (14.1V for a "12V" 6 cell battery). Since these voltages are below the "gassing" voltage and cannot degrade the electrolyte, they can be applied to a fully charged battery without overcharging or damaging it. Because the charging reaction takes precedence over any over-charge chemical reactions until the battery is fully charged, you can utilise considerably higher voltages without harming the battery if it is not fully charged. For this reason, a battery charger can run at 14.4 to 15 volts when the charge cycle is in the bulk-charge stage. Modern precision chargers enable safe floating voltages and quick charging, enabling them to be left on.

In order to prevent gassing, 6V batteries must be charged at voltages between 6.9V (float) and 7.5V. (bulk charge).

Since the invention of the basic lead acid battery, many alternative charge techniques have been applied. Because the water in flooded lead acid batteries can be changed, they were crucial in the past when voltage regulation was challenging. Even sealed lead acid batteries may recycle the gases created to prevent harm to the battery as long as the charge rate is slow since the lead acid chemistry is fairly tolerant of overcharging. This allows marketing firms to acquire access to incredibly cheap chargers.

Fully Charged Battery Specific Gravity

When both liquids are the same temperature, the electrolyte in a fully charged battery typically weighs 1.26 times as much as an equivalent volume of pure water. As a result, the battery electrolyte would be said to have a "Specific Gravity" of 1.260, which indicates that it weighs 1.260 times as much as pure water. The sulfuric acid in the electrolyte reacts chemically with the battery plates during discharge, making the residual electrolyte lower in weight. We can identify how much acid has coupled with the plates by calculating the relative weight of the electrolyte, which allows us to calculate how much electrical energy is remaining in the battery. However, it would be inconvenient to weigh the electrolyte directly, so we use a device called a hydrometer instead. This comprises of an enclosed glass hydrometer that is calibrated to read in terms of specific gravity, a glass barrel, and a bulb syringe for sucking up a sample of the electrolyte.

The table below shows typical specific gravity ranges for a cell at different stages of charge in relation to its ability to start the engine at 80°F.

How long does a fully charged battery last?

Typically, a new battery is required for your car every 3 to 5 years.

However, this figure may vary since a car battery's lifespan depends on how long it can maintain its charge and be rechargeable. Since there are several types of automobile batteries, the typical battery life also depends on the chemical makeup of the battery.

The typical battery life of a few popular car batteries is shown below:

Lead acid battery: The typical lead acid battery has a lifespan of three to five years.

A dry cell lead acid battery is a form of gel battery or an AGM battery. An AGM or gel battery with proper maintenance can last an average of 7 years.

An electric vehicle like the Tesla Model S employs lithium ion batteries, which have a somewhat long lifespan. Although they are projected to last 10–20 years, EV batteries like lithium ion batteries frequently have a 5-8 year warranty on them.

NiMH battery: The nickel-metal hydride battery has an average lifespan of 8 years and is frequently used as a hybrid automobile battery
