Did you know that the first watch made an appearance shortly after the year 1500? If you are a watch fan and want to learn more about watch batteries, you are in the right place. We have put together this short guide to share the many kinds of batteries available for different watches. Read on to learn more.
Lithium Button Batteries
These batteries resemble small coins and are usually 3V. The positive electrode on lithium coin/battery cells is either carbon monofluoride or manganese dioxide. The negative electrode is always lithium.
If the positive electrode is carbon-monofluoride, the label starts with “B” and typically it will operate at around -22°F and 185°F. The cutoff voltage is 2.25 V and the minimum voltage is 2.8 V.
Manganese-dioxide batteries will start with a “C” on their label. Their operating temperature ranges between -4°F and 158°F. The cutoff voltage for these batteries is 2.0 V and the minimum voltage is 3.0 V.
Cobalt Titanium Lithium Batteries
These watch batteries are rechargeable and normally they are labeled as accumulators or capacitors. They are very commonly used in wristwatches that have some type of recharging system incorporated into it.
For example, solar watches and automatic watches tend to have this type of battery in it. The biggest pro about this type of battery is that it is truly rechargeable.
Although, when they were first put into watches they had physical small capacitors incorporated into them even though the battery could charge on its own. The most popular type of CTL batteries includes CTL1616, CTL920, and CTL1025.
You can purchase wholesale watch batteries if you are looking to save some money.
Lithium Titanium Batteries
These batteries are also known as MT batteries, and they are another type of rechargeable watch battery. Lithium titanium batteries are similar to CTL batteries, but they have a nominal voltage of 1.5 volts instead.
MT batteries can provide stronger currents and endure a large number of charging and discharging cycles, even though they have a smaller nominal voltage in comparison to CTL batteries.
Storing Energy for Operation
Solar watches use tiny solar panels that collect light from the sun and store that energy to operate when there is zero light present. Mechanical watches use a spring to keep the watch going, but once the spring tension is gone, the watch stops working.
The other common watch is kinetic. Kinetic watches use the energy that comes from a rotor, which spins as the watch moves on the wrist. It stores its energy to use later on while the watch isn’t moving.
Feeling Like a Pro About Watch Batteries?
Now that you are more familiar with the different kinds of watch batteries, you can make an informed decision on which batteries you need for your watches. You can also make your future watch purchases based on the batteries you prefer.
