If you are someone that uses a medical penlight as a part of your daily routine, you will be more than aware of how often you will find yourself reaching for your penlight. If you are a nurse or a doctor, a medical penlight is one of the main tools that you will use throughout the day.  Due to how much they are used and how small they are, you may find that you will have to replace the batteries in a medical penlight quite regularly.  

Due to how small the medical penlights appear to be, changing the battery may seem like a difficult task. However, it is actually quite straightforward, as long as you know all of the steps.

Which batteries will you need?

Before you even consider changing the batteries of your medical penlight, you will first need to know which batteries you will need. Not every penlight is the same and it really depends on the manufacturer, but most penlights use either AA or AAA batteries. You can also check which batteries you need to use by opening up the battery chamber in your penlight, but if you don’t have access to your penlight you can also figure it out with a simple google.  

Where is the battery chamber?

Due to the compact nature of a medical penlight, the battery chamber may not be in an obvious place. With most penlights, in order to access the chamber you will first need to unscrew the bulb. Make sure you don’t do this immediately after using the penlight, as depending on the brand there may be some heat emitting from the light. If the area is cool, you will be able to unscrew the bulb and there will be the battery chamber.

How do you change the batteries?

The process of changing the batteries of a medical penlight is actually extremely straightforward. You simply need to take the batteries that are already in the chamber out and make sure you place the new batteries facing the way that you want to put the new ones. You should also make sure that you take the time to clean the inside of the chamber when you are replacing the batteries. This can be done easily through the use of a cotton bud and will ensure that your medical penlight stays in working order and will prevent any unnecessary premature breakage in the future.  

If you are a medical professional, then you should also know how to correctly use a penlight for medical use, then it is important that you regularly clean your penlight anyway as many germs can get caught on the surface, so why not use the battery changing time to your own advantage.

How long does the battery life last?

Once you have changed the battery of your medical penlight, you may wonder how much battery life you will get out of it. This really depends on the model, but for most you can usually expect to get around three continuous hours of life.
