# Can We Use 1.2 V Batteries Instead Of 1.5 V?

## When should I replace my 1.5 V battery?

A reading of 1.3 to 1.5 volts means the battery is good.

A brand new battery might show a higher voltage level.

Reading at 1.6 or slightly higher is not uncommon, and this is the reason for setting the DCV to a level of 20 volts as the maximum threshold..

## How many volts is a dead AA battery?

1.35 voltsAA batteries start off with 1.5 volts of energy, but the voltage goes down as the batteries are used up. Once the batteries dip below 1.35 volts, they appear to be dead, even though they still have a lot of juice left.

## Is a 1.5 V battery the same as a AA?

The nominal voltage of the cell type in question, which for AA cells will usually be either: 1.5V, the standard nominal voltage for batteries of this size (AA 1.5V batteries are the most common and widely available versions, particularly of alkaline and zinc-carbon cells)

## What is 1.5 volt battery dead?

Re: At what voltage are alkalines considered dead? For 1.5v AA or AAA primary batteries, 1.3v “under load” as tested by your DMM is considered dead. For 1.2v Nicad or NiMH AA or AAA rechargeable batteries, 1.0v “under load” is considered dead.

## How long does a 1.5 V battery last?

The power of a 1.5 V battery varies with the number of hours its in service. According to the chart above, the power discharge for a 1.5 V “D”battery at approximately 210 hours is 0.1 Watts (W). At about 60 hours the power discharge is 0.25 W. At about 40 hours the power discharge is 0.5 W.

## Can AA batteries kill you?

The AA battery does not have enough amperage to kill you. The human body generates a ton of electricity, even more with static air. … But the amperage is very low, only 0.1 or roundabouts. to kill a human, the amps need to be about 3. So batteries have no where near the amount of amps needed to harm a human, in general.

## Are all 1.5 volt batteries the same?

AAA, AA, C, and D batteries are all 1.5 Volts. Regular, heavy duty, and alkaline, all are 1.5 volts. However, current rechargeable batteries, Nickel Metal Hydride, only output 1.2 volts. Most things that operate on 1.5 volts will operate on 1.2 volts, but may not work as well, or only for limited time periods.

## What are 1.5 V batteries used for?

Speaking of their uses, 1.5v batteries can be used to power a huge number of household and industrial electronics that people use everyday. Batteries like this are great for powering devices such as clocks, remotes, smoke alarms, and flashlights.

## Is 11.9 volts enough to start a car?

A flat battery can show 12 volts , but not be good enough to start a car . … 11.9v indicates the battery is completely discharged. Anything under 12.2v means the battery is in a state of discharge, and a healthy battery should show 12.6v in a static state.

## Are all AA batteries 1.2 V?

The proper voltage for AA/AAA alkaline battery is 1.5V. The proper voltage for AA/AAA NiCd/NiMh rechargeable battery is 1.25 Volts. … The NiMH cells will be providing 1.2 volts throughout it’s cycle use while alkaline cells go from 1.6v to 0.9 volts.

## What are the longest lasting AA batteries?

Energizer AA Lithium Batteries, World’s Longest Lasting Double A Battery, Ultimate Lithium (12 Battery Count)

## How do I check the level of my AA batteries?

Drop each battery (with the flat, negative end down) from a couple of inches up. If the battery is charged, it should make a solid thud and most likely stay standing. If, however, the battery is dead, it will bounce and fall over immediately.

## What kind of battery is a 1.5 V?

Duracell AA Alkaline BatteriesDuracell AA Alkaline Batteries 1.5v (2 Pack) MN1500 (LR6)

## How long do batteries last if not used?

Most unused alkaline batteries will last between five and 10 years, while Ni-MH batteries have a shelf life of three to five years of non-use. The greatest threat to keeping batteries in good condition while in storage are environmental factors.

## What is a 1.5 V AA battery?

What is a 1.5v Battery? A classic nominal voltage, most AA, AAA, C, & D cells are 1.5 volts, and many household and handheld devices have been built to use that voltage. The first zinc-carbon dry cells naturally produced 1.5 volts of energy, and has remained the standard ever since.

## What is the smallest battery?

At 150 nanometers wide, the nano battery is hundreds of times thinner than a human hair and more than 60,000 times smaller than a AAA battery. How many “A”s is that? The little battery, developed at Rice University, is actually a cross between a battery and a supercapacitor.

## Are there 1.5 V rechargeable batteries?

Yes, they are finally available. A company called Kentli has released AA and AAA rechargeable lithium polymer batteries that output 1.5 volts.
