Battery Juice- Introduction, Origin and Disposal

Mar 01, 2021   Pageview:50

Battery juice refers to battery acid. It could refer to any acid used in a battery cell, but mostly, the term 'juice' describes the acid used in a lead-acid battery. The lead-acid battery was invented in the late 19th century by Gaston Plante who was a physicist. The Battery acid contains 30-50% sulfuric acid in the water, giving it a 0.8 pH approximately. The batteries have been used for many years in conventional combustion engines and are the lead's dominant market. They are relatively inexpensive despite them having a large power to weight ratio, limited depth of discharge, relatively long service life, easy to recycle, and simple recharge. These features make the batteries attractive to be used in motor vehicles and any automotive.

In this article, we will discuss why lead-acid batteries are called juice, where the battery juice comes from, and ways of squeezing more battery juice. Let's get started.

Why is the battery called juice?

You might ask yourself, why is the battery acid referred to as juice? Why not liquor, water, or soda? The name in itself is not fitting when you look at the context of acid and juice. They are different fluids, the juice being a high sugar drink while acid being acidic. Anyway, we still use juice as a metaphor for battery acid.

The battery juice came to its name due to its strength, vitality, and power to sustain the cells in a battery that power an engine.  Just like fruit, when you extract all the fluids or juices, it becomes shriveled, hollow, and non-nutritious. Same as a battery, without the juice, it becomes obsolete and pretty much useless. In using such a comparison, the juice is the very essence that makes a battery reliable, usable, and important. This is not to say that the juice term is a drink, but rather electrolytes that power the battery cells. There are a lot of written records that show the use of this term since the late 1800s. For example, according to Daily News (Los Angeles), on 9 October 1997, "Electric cars have a range of about 80 miles before they run out of juice." Such a statement might have been used to mean charge or power.

All in all, juice can also be used as a metaphorical term that means current, electricity, or power. Different people have different meanings when using the term. For example, someone can say battery juice to mean the charge left in a battery; another person can say 'turn on the juice' to incidentally mean, 'turn on the charge' or ignite the engine. In short, when it comes to meanings and the origin of the term, battery juice goes hand in hand with electricity.

Where does the battery juice come from?

As we know by now from the discussion above, battery juice is lead-acid or lithium-ion.  The juice comes from lithium which is a metal found free. Some of the lithium's features include;

●It is a soft metal to cut through.

●It is the lightest metal on earth.

●It is very diffusive.

●It is the least dense solid element.

●It floats in oil and water. Though it is not advisable to expose it to moisture as it reacts and burst into flames due to its alkali nature. Thus it is known to be highly corrosive and reactive.

Therefore, lead-acid battery juice consists of sulfuric acid in water. It has two plates separated by this liquid. The battery is rechargeable due to this electrolyte liquid making it possible to charge and discharge.  The electrolyte contains charged ions of sulfate and hydrogen.

When a battery is discharged, the sulfuric acid in the electrolyte is almost depleted to closely resemble water, while the sulfate from the acid coats the plates is reducing the surface area where the chemical reaction takes place. In short, the sulfate ions move from the negative plates and give up their negative charge. Charging the battery reverses this effect, driving back the sulfate into the acid. The back and forth movement of these ions around the electrolyte is what creates the current flow, thus causing a battery to work.

Lastly, the movement of ions in the electrolyte liquid to create a current flow is what powers a battery and an engine. This is where the battery juice comes from.

How do you squeeze more battery juice?

The more functionality we pack into our gadgets and engines, the more power they need to consume to run. Just like smartphones' batteries, car batteries also need to be recharged from time to time. Most people only think about their batteries when it's time for a replacement. Hence a battery running out of juice can be a big annoyance and nuisance. Such situations have prompted people to come up with ways of squeezing more juice from the battery. Here are some methods.

1.Battery swapping- in case of AA or AAA batteries are running down, try swapping their positions.

2.You are mixing older, almost-discharged batteries with new ones.

3.Hand me down approach-where the batteries that no longer power a high output device can be used in low output devices. For example, moving batteries from a digital camera to a speaker remote.

When it comes to squeezing out more juice from phone batteries, here is what you can do to;

1.Change settings- enable the battery saving mode in your Smartphone settings to extend battery life.

2.Updating your phone's operating system.

3.Decreasing the brightness level and screen timeout.

4.Watch the temperature of your phone-a lithium-ion battery maintains its optimal long-term charge when stored in temperatures between 32 and 113 degrees Fahrenheit. Any temperatures below or above this can degrade your battery.

5.Turn off Bluetooth and Wi-Fi.

6.Always charge your phone whenever the battery percentage seems over-depleted for extra battery strength.

These are only a few out of the many ways you can squeeze more battery life and be able to learn to conserve the battery strength available.


It is nice to learn and know some in-depth information about our gadgets and vehicle batteries. The article above provides you with background information on battery juice and different ways you can squeeze out battery juice to increase battery strength and performance time. I hope that you find the information enlightening and helpful.
