Sometimes you may require batteries that have a better voltage. But almost all of our household batteries are of the smallest voltage.
Only the specialized batteries have a higher voltage rating. But that’s not regularly available in our household.
So, why are rechargeable batteries 1.2v actually?
Rechargeable batteries’s voltage is 1.2V because of the chemistry of the battery cell. During discharge, a fully charged cell provides an average of 1.25 volts per cell. These batteries are environmentally friendly since they consume less energy. Another major advantage is, this saves a lot of money.
Not being a tech expert could make you feel a little noob. But, don’t get stressed. Continue reading to know all the necessary information.
So, let’s dive in!
Reason Behind Rechargeable Batteries Being 1.2 V
There are basically 3 types of nickel-based alloys that make up the rechargeable batteries.. Three nickel-based alloys are nickel-iron, nickel-cadmium, and nickel-metal hydride.
A 1.4-volt open circuit voltage drops to a 1.2-volt discharge voltage after the battery is fully charged. The nominal cell potential of a Ni-Cd cell is 1.2 volts (V). The terminal voltage of a Ni-Cd cell fluctuates very little during discharge.
While discharging, a fully-charged cell provides an average of 1.25 V/cell, which decreases to 1.0–1.1 V/cell. The nominal voltage is just 1.2 volts.
In order to avoid confusion, 1.2V was chosen as the label voltage. Since it was near the normal value of the three cells’ chemistries in question.
5 Reasons to Choose 1.2V Rechargeable Batteries
Some might wonder are all rechargeable AA batteries 1.2 volts? The answer is No. There are few rechargeable batteries that follow this requirement.
Rechargeable batteries may use again saving a significant amount of money over the course. Once purchased, it may be recharged a thousand times.
Now, are all rechargeable batteries NiMH? Rechargeable NiMH batteries are highly popular simply because they are incredibly ecologically friendly. Be considerate of your wallet. There’s also a matter of nicad battery’s lifespan.
Are rechargeable batteries renewable or nonrenewable?
The rechargeable batteries are renewable and environment friendly. You may use your rechargeable batteries like any other normal battery after they’ve been charged.
After a few changes, you won’t be spending money on ‘non – biodegradable’ batteries. Apart from being environment friendly, they are quite good for some other characteristics too.
Reason 1: Easier to Use
Using a basic battery charger, you can simply and comfortably recharge rechargeable 1.2V batteries. Battery chargers come in a range of styles that are always improving in terms of convenience. It also adds reliability, ease of use, and durability.

Because we use so many various kinds of batteries. Now, do 1.5V rechargeable batteries exist? Well, they are now accessible. Kentli has launched a 1.5-volt lithium battery.
Certain battery chargers can charge a wide variety of them. A power socket or a USB port may use to charge battery chargers.
I’ve curated some of the best battery chargers for your 1.2V batteries. If you don’t have one I urge you to get one today.

Here’s a very cheap alternative to the chargers I’ve mentioned earlier.
Reason 2: Superior Battery Performance
Now, you might wonder, can we use 1.5 V batteries instead of 1.2 V?
All the time, rechargeable batteries draw 1.2 volts of energy. At 1.5 volts, disposable batteries are the most common kind of battery. But, they gradually decrease in voltage until they are completely dead.
You now have more options than ever for charging your batteries, regardless of your budget. And you won’t have to worry about issues like matching the lipo battery with the motor.
Some battery chargers include a refresh mode’ that drains your rechargeable batteries.
Using this mode and function, you can be certain that your 1.2V batteries will operate. It will perform at its peak efficiency and lifespan at all times.
Reason 3: Environment Friendly
Based on sustainability, rechargeable NiMH batteries are preferable to disposable NiCd batteries. Now, are all NiMH batteries 1.2 V?
The voltage of a cell varies depending on the chemistry of the battery. In all NiMH and NiCad battery chemistries, the nominal voltage is 1.2 volts direct current (Vdc). The voltage with alkaline batteries is 1.5 volts DC. 3.6 or 3.7 volts.
Rechargeable batteries generate less waste since they may be recharged and reused hundreds of times. A battery charger is more efficient than producing fresh batteries in terms of both cost and energy.
Reason 4: Time Saver
Recharging batteries may save you a lot of time. Put the charged batteries in the gadget and the dead ones in the charger.
That’s all there is to it. The time it would take to go to the shop, find the batteries, and pay for them. And getting home to use them is much shorter if you already have recharged batteries on hand.
Reason 5: Saves a Lot of Money
However, if you consider the long-term benefits, it may be worthwhile to invest in rechargeable batteries. Batteries that can be recharged more than 500 times are known as rechargeable batteries 1.2V.
You can buy a battery charger with a built-in timer for as little as $10. It preserves and extends the life of your rechargeable batteries.
There is no need to worry about the quality of the batteries and chargers you purchase.
Using rechargeable batteries not only saves you time and money. They are also better for the environment since they can be recharged again and again.
Here are some suggestions for less costly 1.2 v rechargeable batteries.

A Few Cons of 1.2V Batteries
Much like any other thing in this world 1.2V batteries have some cons as well. We’ve already mentioned some of them throughout everything but here is an overview again.
Rechargeable batteries 1.2V have some minor drawbacks. But you can still choose this one at your convenience.
Prices might seem a bit too much compared to other good chargers. But, look at the bright side cause it has rechargeable features.
An older rechargeable battery may also grow weaker and less reliable. Slow depletion and poor performance may result. So, good maintenance is the key. Even high-quality rechargeable batteries will eventually need to be changed.
How Can 1.2 V Rechargeable Batteries Be Used in 1.5 V Devices?
With 1.2 V batteries, there is no difference in performance. In reality, the 1.5 V of an alkaline battery’s first discharge is its sole value.
Afterward, it continues to fall steadily until it’s far below the 1.2 V threshold. A value of 0.6 V marks the end. Between 0.9 V and 1.5 V, the vast majority of electronic devices can operate without issue.
Rechargeable batteries of 1.2V maintain a steady voltage of 1.25 V throughout the duration of the operation. Unlike the alkaline batteries.
When it comes to high-energy devices the newest rechargeable batteries really exceed alkaline batteries.
FAQs
Does it matter what charger I use for rechargeable batteries?
Decide on the best approach. Rechargeable batteries should always be charged in the device they were originally intended for. Use the charger that came with it, or with what manufacturers recommend. Thus combining chargers and batteries might cause issues.
Why are rechargeable AA batteries made to be 1.2 V while alkalines are 1.5 V?
1.2-volt renewables hold their charge better than alkalines. Batteries for 1.5 volts may start out at 1.5. Or, 1.6 but degenerate to 1.2 in a short period of time, to roughly the 1. v level. At some point, they become worthless. It is possible to charge the 1.2v to a greater voltage. However, alkalines lose their charge more quickly.
Are rechargeable batteries worth it?
High-drain gadgets that use a lot of energy fast benefit greatly from rechargeable batteries. Rather than squandering throwaway batteries and money by using them up so rapidly. Invest in a set of rechargeable batteries. In the long term, you’ll save money and time this way.
Conclusion
I hope all the confusions are clear about why are rechargeable batteries 1.2V? Honestly, these are the purchases that will serve you a long time.
A decent battery charger is a must if you’re planning to utilize rechargeable batteries. However many lack automatic shut-off capabilities to avoid overcharging and severe damage.
Best of Luck!
