In this article, we’ll teach you everything you need to know about replacing the battery in a bass guitar and how often you should do it. So if you’re a bassist or are just curious about electric bass, this post is for you!

How often should you change the battery in a bass? The battery in your active bass should be changed at least once every six months if you play it often. Two major factors are the battery’s life expectancy and how frequently you use an amplifier to hone your skills in preparation for live performances. Although batteries often last longer, a safe rule of thumb is to replace them every six months to avoid ever having to deal with a power outage on stage.

The signs of a dying battery in a bass

Even though active bass preamps and EQ are great, if you play your bass a lot, they can eventually drain your battery. So, you may be playing your active bass one day and realize that something doesn’t feel right; it does not sound as nice as it did yesterday.

Although the change happens slowly at first, there comes a tipping point when it can no longer be ignored. A lot of new musicians may assume their instrument or amplifier is broken when, in fact, it only has a dead battery.

  • If the battery in your active bass dies completely, you may notice the following.
  • Snapping/unwanted bending of sound
  • Faint transmission
  • When you recognize these symptoms of a dead or dying battery in your bass guitar, however, the problem is easily fixed.

Most active basses have a small space in the back where you can store a set of 9-volt batteries. These batteries can be bought in packs for a low price. On the other hand, it is sometimes built into the cavity along with the other electrical parts. Remove the lid (either by unscrewing it or popping it open) and insert a new battery.

In addition, if you find yourself without a spare battery or access to a shop, certain active basses let you convert to passive mode. If you want to keep using the active preamp and EQ, it’s a good idea to have a spare in your case or gig bag.

How often should you change the battery of a bass?

If you use your active bass often, its battery will need to be changed every four to six months. So even though batteries are compact, you may still get a lot of use out of them in your bass.

If you take care of your battery properly, you can use it for a whole year. However, the battery life of your bass guitar may be extended by unplugging it while you’re not using it. Continue reading to find out more about this.

How to change the battery in a bass?

When it’s time to change the battery in your active bass, it’s a simple and fast process. A screwdriver and the instructions below are all that is required.

Flip the bass over.

You may usually find two chambers, separated by screws, on the back of your bass. The biggest will protect the electronics in your bass, while the smallest will hide the battery.

Throw open the cover.

To complete this step, you will need a little screwdriver. Please use it to take the cover off the smaller storage area.

Disconnect the present battery.

The internal battery will have dangling cables attached to it. Please don’t put too much force on them or pull too hard since it might damage them. Battery side clamps are another possible means of safeguarding the battery.

In such a circumstance, you may need to use your screwdriver to pry the battery up from between the clips. You’ll need two batteries for certain basses’ electric motors. If this describes your bass, you need to switch to the second battery and start again.

Put the fresh battery in place.

After the old battery has been removed, the new one should be put in. Plugging in a fresh battery to the bass’s circuitry is the last step. Put the bass’s cover back on when you’re done, and tighten the screws.

When should you change the battery in a bass?

The battery life of your bass should be monitored often, and the battery itself changes when it is almost dead. If the battery is even somewhat low in power, it should be replaced before a performance.

There are two options for changing the battery in your active bass. One way to ensure that it doesn’t suddenly die on you is to replace the batteries every six months. The second is to monitor the battery’s health using a voltmeter so that you only need to replace it when it is almost dead.

If you replace the battery every six months, you won’t have to worry about it for a while. You may be certain that it will never give out on you and that replacing it will become a rare part of your bass’s routine maintenance.

A voltmeter allows you to check your battery’s health and determine how much time you have left before it dies. It’s more reassuring to know it won’t suddenly shut off on you, and it saves money by preventing you from having to throw away partially used batteries.

It’s possible to get a battery tester like this one for around ten dollars if you’re concerned about saving money and the planet by not needlessly replacing batteries. In addition, using this method, you can determine how much juice is still in the batteries.
