How Long Do Batteries Last In Guitar Pedals

For those who perform on stage and jam regularly, a pedal is one of the most important things. However, for a guitarist battery life of a guitar pedal is quite a headache. Most of us do not even know how long do batteries last in guitar pedals. And we’re sure you do not want to be one of them.

Gauging the battery life of a guitar pedal is hard. However, on average, a low drain pedal, like distortions and overdrives, has a battery life of 60 hours on average, and a more complex pedal offers at least 10 hours of battery life.

Now, if you wanna know more about the battery life of a guitar pedal, following the article below is going to be your perfect bet.


What Is The Average Life Of Guitar Pedal Batteries?

The average life of a guitar pedal battery depends entirely on the type of pedal that you use. Usually, in most cases, the battery of a guitar pedal can last between 2 to 35 hours with ease. So, what exactly makes the change?

Well, the current draw of any guitar pedal battery depends on the average draw of the battery. A pedal with a higher draw reaching as much as 170mA has the ability to last as long as 2 hours. This is the type of pedal that you would not like to have for a long gig.

However, on the other hand, a pedal with a 30mA will last as long as 30 to 60 hours. These are the pedals that most of us prefer. But, if you have a pedal with a higher battery draw, you need to always stock extra batteries.

Can You Gauge The Remaining Battery Life In the Pedals?

This is something that confuses most guitarists, and almost all of us have tried to know whether or not it is possible to gauge the remaining battery of a guitar pedal. Well, this is sad, but we cannot gauge the remaining battery of a guitar pedal.

Neither the pedal nor the guitar or the amp has any indication about the remaining battery life of a battery installed in a pedal. So, if you are a guitarist and use a pedal on a regular basis, you will have to do everything on assumptions.

Initially, it will sound hard, but with time you will get used to it; there will be no one who knows the remaining battery in your guitar pedal. Along with it, the pedal type you use will also indicate the remaining battery life. A high-draw pedal will have low battery life, and a low-draw pedal will have higher battery life.

Will Pedals Drain Batteries When Turned Off?

Drainage of the battery in a pedal is one of the most irritating things for a guitarist. There are cases when you do not use your pedal for long and when you connect it, the pedal is out of battery. This happens because most of the pedals stay on even when they are disconnected and they use the battery installed in them.

However, there are some pedals that bypass batteries when they are not connected to any guitar so that they can avoid battery drain. These are the pedals that most guitarists use nowadays as they help you save battery for future gigs.

But, in case you leave a true bypass pedal connected, they will tend to drain the battery. So, if you want to save battery, make sure that the pedal is perfectly disconnected.

If you are using a high draw pedal with 170mA, the pedal will only survive between 2 to 3 hours on a 9V battery. But, if you are using a low-drain pedal, such as distortion and overdrives, the battery will last for as many as 60 hours.

So, the average life of a 9V battery in your guitar pedal will depend entirely on the pedal you use. If you need your battery to last longer, use a low-drain pedal. But, if you have no concerns with battery timing, you are good to use any pedal you want to.
