## What can I use instead of D Battery?

Electrically, one AA could do this job since it runs at the same voltage as a D battery. However, it was easier to combine 4 AA’s into one battery to simulate the size of a D battery and effectively replace it.

## When should I replace my 1.5 volt battery?

You might wonder at what voltage is a 1.5 V battery dead. If the battery tests at less than 1.3 volts in the multimeter, it no longer functions properly and should be replaced.

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.

## At what voltage are 1.5 V batteries dead?

AA 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.

## At what voltage Should a battery be replaced?

If the measured reading is less than 12.2 volts, the battery’s resting voltage is weak, which means it most likely needs to be charged or replaced.

## How can you tell if a car battery needs replacing?

Here are seven telltale signs that your car battery is dying:

1. A slow starting engine. Over time, the components inside your battery will wear out and become less effective.
