Watch Battery

A foundational skill in the world of watchmaking is knowing your watch batteries and how to replace them. It is one of the most common tasks and a routine maintenance step for quartz and digital watches.

There is no avoiding changing watch batteries but when initially approaching the replacement, you may be stuck on how to change it and which battery to go for. Whilst there may be some initial confusion, the replacement of watch batteries is a relatively simple task and we have all the information, tips and tricks that you need right here.

Signs That Your Watch Batteries Need Replacing

As time ticks on, your watch battery may start sending subtle signals that it’s nearing the end of its lifespan. There are many signs that your watch battery needs replacing and of course, the most obvious one is if the watch stops altogether, even after being worn regularly. If your watch completely stops ticking, chances are, it needs a simple battery replacement. However, this is not the only sign that your watch battery needs replacing.

One of the other most evident signs is a slowing or irregular movement of the second hand. If you notice that your watch’s second hand is lagging or moving differently than usual, it’s a strong indication that the battery is losing power.

If your watch has a backlight or any illumination, a dimmer light is also a key signal. If your watch’s dial or digital display becomes less visible in low-light conditions, it’s often a sign that the battery powering the backlight is weakening.

In the case of digital watches, fading or missing display segments may also suggest the end of a battery. Plus, if your watch has multiple functions or complications, such as a chronograph or alarm, these additional features may stop working or become temperamental when the battery is low.

If you observe any of these signs, it’s typically a reminder that your watch needs a new energy source. When it comes to your watch, it is important to trust your instincts and if you notice your watch suddenly behaving differently, it’s time to consider a battery replacement. Regular maintenance and prompt battery replacement will not only keep your timepiece accurate but also extend its longevity.

Types of Watch Batteries

Since all watches use a button cell battery (also known as coin cell batteries), it is easy to assume that one size fits all and all watches take the same battery. However, this is not the case and in fact, there are many different types of watch batteries. Not only are different sizes available, but there are also different types of battery chemistry that may be worth considering.

Watch Batteries


Among the pricier options, lithium batteries offer longevity, featherlight weight, and superior temperature tolerance compared to their counterparts. These batteries can last for up to ten years in storage.


Silver-oxide batteries are the most commonly used in watches and maintain a consistently stable voltage throughout their usage. This feature makes them ideal for watches as they provide reliable and predictable voltage.


Alkaline batteries are less used but more budget-friendly. They excel in delivering high current rather than maintaining steady voltage and are greater suited to things that demand bursts of power such as toys.

Zinc Air

Zinc-air batteries have a short life span and are rarely used for watches.


Mercury oxide, like silver oxide, ensures a stable current. However, it is banned in some destinations due to environmental concerns.

Where Can I Go To Get A Battery Watch Replaced?

When it’s time for a battery replacement, you may wonder where you can go to give your trusted timepiece a new power source. There are many options to choose from including the manufacturer, local jewelers and dedicated watch repair shops.

How Not To Change Watch Batteries

When it comes to changing a watch battery, precision and careful execution are essential. However, there are several common mistakes that should be avoided to prevent damaging the timepiece and ensure a successful battery replacement.

Skipping Research

Not all watches are created equal. Different watch models and brands have specific requirements for battery replacements. Skipping research and using a battery that doesn’t match your watch’s specifications can lead to poor fit, functionality issues, or even irreversible damage.

Lack of Proper Tools

Attempting a battery replacement without the right tools can lead to scratched cases, damaged seals or misalignment of components. Proper screwdrivers, tweezers, and other watchmaking tools are essential.

Forgetting the Gasket

Many watches have a rubber gasket that helps maintain water resistance and protects the internal components. Neglecting to remove and reinsert the gasket during battery replacement can compromise the watch’s water resistance by allowing moisture to seep in and damage the movement.

Disregarding Polarity

Watch batteries have a positive and negative side. Placing the battery upside down or reversing the polarity can damage the movement and circuits. Always note the correct polarity before inserting the new battery.

Using Excessive Force

Applying excessive force when opening the watch back, removing the battery, or resealing the case can lead to cracked crystals, broken case backs, or misaligned components. Gentle and controlled movements are key to preventing unnecessary damage.

Hitting the Battery Out

Resist the temptation to forcefully tap the open watch back onto your palms, hoping to dislodge the old battery. The watch and movements are incredibly fragile and mishandling it could result in immediate damage. Taking your time ensures a smooth and successful battery replacement without jeopardizing the delicate components of your watch.

Potential Issues If Watch Batteries Are Not Changed

If watch batteries are not changed when they need replacing, this can cause multiple potential issues. Neglecting to change a watch battery can lead to a range of potential issues that extend beyond the inconvenience of a non-functional timepiece. Failing to address battery replacement promptly could result in a variety of complications.

Voiding the Warranty

Many watch manufacturers stipulate that battery replacements should be performed by authorized service centers. If this is the case for your watch and you were to ignore this requirement, it might invalidate your warranty. Certain brands may refuse responsibility for any damage resulting from unauthorized battery replacements leaving you with potential repair costs.

Degrading Performance

Some watches decline in performance after being inactive for an extended period. Failure to replace the battery in a timely manner might lead to internal components deteriorating, causing the watch to struggle with accurate timekeeping and smooth operation upon restart.

Warped Back

Bulging batteries are a common issue arising from poor-quality replacements or improper installation. A bulging battery can exert pressure on the watch case, potentially warping or damaging it. This not only affects the aesthetic appeal of the watch but also hampers its functionality.

Risk of Explosion

If batteries are used beyond their lifespan, this can cause potential safety hazards. Certain types of batteries, when subjected to excessive heat, can explode and this risk is increased if used past their lifespan. Ensuring proper battery replacement minimizes the risk of such hazardous occurrences.

Unreliable Timekeeping

As a watch battery’s energy depletes, it may cause erratic timekeeping including irregular ticking. Relying on a watch with unreliable timekeeping defeats the purpose of owning a timepiece and can lead to missed appointments or important events.

Corrosion and Damage

Dead batteries can leak releasing corrosive chemicals that damage the internal components of the watch. Corrosion can compromise the delicate mechanics of the movement and to costly repairs.

Neglecting watch battery replacement can have far-reaching consequences from warranty issues and performance degradation to potential safety hazards. Regular and timely battery replacements ensure your timepiece remains accurate, and functional and retains its value over time.

How To Clean A Corroded Battery Compartment

Cleaning a corroded battery compartment is essential to prevent further damage and ensure the proper functioning of your device. Follow these steps to safely clean the corroded battery compartment:

Step 1: Gather Supplies

You’ll need a few basic household items: white vinegar, cotton swabs or a soft brush, baking soda, and a clean, dry cloth.

Step 2: Safety First

Before starting, make sure the battery is removed, and wear gloves and protective eyewear to avoid direct contact with the corrosion or any chemicals.

Step 3: Create a Cleaning Solution

Mix a small amount of white vinegar with water in a bowl using a 1:1 ratio. For stubborn corrosion, you can make a paste by mixing in baking soda with a small amount of water.

Step 4: Apply the Cleaning Solution

Dip a cotton swab or soft brush into the vinegar solution or baking soda paste. Gently scrub the corroded areas of the battery compartment. Be careful not to scrub too vigorously as you could cause damage.

Step 5: Wipe Clean

Use a clean, damp cloth to wipe away the vinegar or baking soda residue. Make sure the compartment is completely dry before proceeding.

Step 6: Neutralize the Acid

If using vinegar, dampen a cloth with water and wipe down the battery compartment again to neutralize any remaining acid. Dry thoroughly.

Step 7: Inspect and Test

Once the compartment is clean and dry, inspect it for any remaining corrosion or damage. Make sure it is clean and free of residue. Insert a new battery and test to ensure the watch is working.

Remember, if the corrosion is extensive or you’re uncomfortable cleaning it yourself, it’s best to seek professional assistance or take it to a watch repair shop. Regular maintenance can help prevent battery corrosion in the future.
