Silver-Oxide/Alkaline Button/Coin Cell Batteries
Button/coin cell batteries, commonly employed in wristwatches, are a type of non-rechargeable battery.
They encompass various chemistry types, with the most prevalent being alkaline and silver-oxide batteries.
Additionally, there are zinc-air batteries available, primarily utilized as hearing aid batteries. However, their usage in watches is limited due to their relatively short lifespan.
Formerly, mercury-oxide batteries were extensively utilized in wristwatches. However, their usage has ceased due to environmental concerns associated with their mercury content.
A comparison of these chemistries is given in the following table:
| Chemistry | Alkaline | Silver-Oxide | Zinc Air | Mercury-Oxide |
| Voltage | 1.5V | 1.55V | 1.4 -1.45V | 1.35V |
| Notes | Voltage drops over time | Very constant voltage | Slightly lower voltage, large capacity; mostly used as hearing aid batteries |
Slightly lower voltage contains mercury; not in use anymore |
| Typical Labels | LR##，LR####，AG## | SR##.SR##SW.SR####SW, SG## | PR##，P##，Z## | MR##，MR#### |
| Typical LR626，SR626SW Capacity | 15-17 mAh | 25-27 mAh |
Alkaline batteries: Alkaline button/coin cell batteries are economical and reliable power sources. They typically maintain a nominal voltage of 1.5 volts, although this voltage decreases as the battery is depleted. However, due to the constant and relatively high voltage required by many wristwatches, the actual capacity of alkaline batteries may seem low, necessitating frequent replacements. Conversely, when used in devices tolerant of lower battery voltage, alkaline batteries offer a larger nominal capacity, resulting in longer usage times. Generally, newer alkaline batteries boast a shelf life of at least 3-5 years.
Silver Oxide batteries: Silver-oxide button/coin cell batteries are highly favored for wristwatches. They are cost-effective, with shelf lives often exceeding 10 years. These batteries maintain a consistent voltage output during operation, closely matching the nominal voltage of alkaline batteries (1.55 V compared to 1.50 V). Notably, the typical capacity of silver-oxide batteries, such as the SR626SW, ranges from 25-27 mAh, surpassing the capacity of equivalent alkaline LR626 batteries (15-17 mAh).

Lithium Button/Coin Cell Batteries
![]("C:\Users\LENOVO\Desktop\SR920SW-Watch-Battery.jpg")
Lithium button/coin cells predominantly consist of primary (non-rechargeable) 3V batteries. They feature a lithium negative electrode paired with either manganese dioxide or carbon monofluoride as the positive electrode.
Manganese dioxide lithium batteries, identified by labels starting with 'C', typically operate within a temperature range of -20°C (-4°F) to 70°C (158°F). They maintain a nominal voltage of 3.0 V, with a cutoff voltage of 2.0 V. An example is the CR2032 battery, boasting a typical capacity of approximately 225 mAh.
Carbon monofluoride lithium batteries, labeled with 'B', generally operate within a temperature range of -30°C (-22°F) to 85°C (185°F). These batteries feature a nominal voltage of 2.8 V and a cutoff voltage of 2.25 V. An example is the BR2032 battery, with a typical capacity of around 190 mAh.
BR#### and CR#### batteries are largely interchangeable, with the slightly lower voltage of BR#### batteries posing no significant issue for most common devices. However, for devices operating in extreme temperatures, BR#### batteries are often recommended over CR#### batteries.
Rechargeable lithium button/coin cell batteries typically have lower nominal capacities compared to non-rechargeable CR or BR batteries. However, they offer the advantage of being rechargeable, capable of enduring up to or even exceeding 1000 charging cycles. Commonly labeled as LiR####, these batteries maintain a nominal voltage of 3.6 or 3.7 volts. Additionally, there are rechargeable 3.0-volt VL series (Vanadium Lithium rechargeable battery) and ML series (Manganese Lithium rechargeable battery).
For instance, the LiR2032 (or LIR2032, ML2032, etc.) has a capacity ranging from 50-80 mAh, whereas the CR2032 battery typically offers a capacity of approximately 225 mAh.
Replacing CR or BR batteries with LiR batteries should only be considered if the device operates effectively when powered with 3.6V (instead of 2.8 or 3.0V). The 0.6V difference may cause operational issues or even damage certain devices. However, the potential for over 1000 charging/discharging cycles can yield significant cost savings.
For watches utilizing lithium batteries, opting for a quality CR#### battery is advisable due to its higher capacity. BR#### batteries are preferable for watches intended for use in extreme temperature conditions.

The most common lithium coin cell wrist watch battery is the CR1216 battery, but other batteries are used as well, like CR2016, CR2032, CR2025, CR2430, CR1220, CR1620, CR1616, etc.
These batteries are commonly used in many small devices, gadgets, and appliances, and getting a new one should not be a problem.
CR1216 Watch Battery
CR1216 watch battery is a non-rechargeable manganese lithium battery featuring physical dimensions of (D x H) 12.5 x 1.6 mm and a nominal voltage of 3.0 volts and a typical capacity of ~25 mAh.
Again, actual capacity depends on the application, watch use, temperature and similar - if You have a wrist watch with an alarm, LED lights, and similar, the use of such features can significantly shorten the runtime of the battery.
CR1216 can be replaced with a BR1216 battery (carbon-monofluoride lithium battery) which features a slightly lower, but more stable voltage, and lower discharge current - hence, the BR1216 battery should NOT be used with watches that feature an alarm, LED lights, and similar features.
LiR1216 are very rare batteries, but they also feature nominal voltage in the 3.6-3.7 volts range and it is questionable which 3.0 volts devices support the use of 3.6-3.7 batteries.
If You need a rechargeable 3.0 volts 1216 battery, the ML1216 battery is a much better choice. However, that battery is usually manufactured with tabs and is also rather rare.
In the end, if You need a round ('R') 12.5 x 1.6 mm 3.0 lithium battery, go for a CR1216 battery (non-rechargeable lithium-manganese battery) from reputable brands and replace them when required.
For the most up-to-date offers and prices, feel free to check the CR1216 Battery Amazon link (the link opens in the new window).
Lithium 3.0V non-rechargeable CR2016 battery is a button/coin cell battery featuring physical dimensions of (D x H) 20 x 1.6 mm (0.7874 inches x 0.06299 inches), thus '2016' as part of its label.
CR2016 battery feature a nominal voltage of 3.0V, a cutoff voltage of 2.0V, a typical capacity of ~90 mAh, a maximum continuous discharge current of ~1 mA, a nominal continuous discharge current of 0.1 mA, and a maximum pulse current usually in the 5 mA and 15 mAh range.
As such, CR2016 is suitable for both analog and digital watches, with or without an alarm and LED lights.
Typical labels of Lithium Manganese Dioxide (Li-Mn02) 20 x 1.6 mm batteries include DL2016, ECR2016, E-CR2016, SB-T11, 5000LC, and similar, but the most common one is CR2016.
Button/coin cell 20 x 1.6 mm batteries are also offered in other chemistries as well:
The BR2016 battery is a Carbon-Monofluoride Lithium battery, delivering a nominal voltage of 3.0V and boasting a cutoff voltage of 2.0V. With a nominal capacity ranging from 60-75 mAh, it operates at a nominal discharge current of approximately 0.03 mA (30 μA).
However, what sets the BR2016 battery apart is its lower self-discharge rate and wider operating temperature range when compared to a typical CR2016 battery.
In contrast, the LiR2016 battery is a rechargeable Lithium-Ion battery with a nominal voltage of 3.6-3.7 volts and a cutoff voltage of 2.7-3.0V. It typically offers a capacity of 20-25 mAh, with some models supporting 500 or more charging/recharging cycles.
It's important to note that both BR2016 and LiR2016 batteries are not directly compatible with CR2016 batteries. They can only be used to replace CR2016 batteries if explicitly allowed by the watch manufacturer.

Cobalt Titanium Lithium Button/Coin Cell Batteries - "CTL" Watch Batteries
Cobalt Titanium Lithium button/coin cell batteries, for short "CTL" batteries, are rechargeable type of watch batteries that are also often labeled as 'capacitors' or 'accumulators' and are used to power wrist watches with some sort of recharging system, including automatic watches, solar watches and similar.
Note: when first automatic/solar watches appeared on the market a long time ago, they actually had little capacitors and not the batteries to store the charge - hence, rechargeable watch batteries are still sometimes referred to as 'capacitors' and not batteries.
But, CTL watch batteries are true rechargeable batteries.
The most popular CTL batteries are CTL920, CTL1616, and CTL621 batteries, while CTL1025 and a few other batteries are not being used very often.
CTL batteries feature a nominal voltage of 2.3 volts, a charging voltage of 2.5-2.7 volts (using constant voltage charging system), and a cutoff voltage of approximately 2.0 volts.
Note: rechargeable CR batteries (this is sort of the wrong statement, since CR batteries are not rechargeable batteries at all, but in order to simplify few things, we use the term 'rechargeable CR batteries') are often labeled as LiR or ML batteries (for example, rechargeable CR2032 is actually LiR2032 or ML2032 battery) and they feature a nominal voltage of 3.0 volts (ML batteries) or 3.6 - 3.7 volts (LiR batteries). Never use ML or LiR battery instead of CTL battery and vice-versa! ML and LiR rechargeable batteries are not commonly used in wrist watches - they are mostly used as memory backup batteries, in communication devices, PCs, medical devices, etc.
The nominal capacity depends on the battery size/volume, continuous drain current, temperature of use, number of charging/discharging cycles, depth of discharge, and similar.
Note: we use Panasonic CTL batteries as examples because they are often a default choice of many solar watch manufacturers, they perform well and can be easily found at various online shops. Also, Panasonic CTL920F battery (or sometimes CTL920A) is a 'CTL920' battery.
CTL batteries can come with or without tabs. Obviously, those without tabs are easier to replace at home, however, if You are not sure what needs to be done and how, do yourself a favor and take the watch to the watch repair shop and let them replace the battery for You.
The following cross-reference chart lists the most popular CTL batteries and their most important features and specifications:
| Battery | CTL621 | CTL920 | CTL1616 |

Replacing a Watch Battery
When it comes to replacing a watch battery, it's crucial to prioritize safety and precision. If you're uncertain about the process, it's best to leave it to the professionals. Taking your watch to a repair shop ensures proper inspection and battery replacement, as the issue might not solely be related to the battery if the watch has stopped working.
Selecting the right battery for your watch is essential. Follow the manufacturer's recommendations closely. If your old battery was alkaline and your watch supports silver-oxide batteries, opt for the latter. While alkaline batteries may be slightly cheaper, the cost difference is usually minimal.
Refer to the watch Owner's Guide for detailed specifications on the required battery size, model, type, and chemistry. Additionally, explore the provided instructions, whether written or in video format. Some manufacturers even mandate that battery replacements be performed by licensed watch repair shops.
If your watch is still under warranty, avoid attempting to replace the battery at home. Instead, take it to a repair shop or send it to the manufacturer for professional service.
Ensure you have the necessary tools for the task. While some watches can be opened and their batteries replaced with basic tools like a toothpick, others may require specialized watch repair kits available online.
Once equipped with your watch, new battery, Owner's Guide, and tools, battery replacement becomes relatively straightforward. Follow the manufacturer's instructions meticulously.
Keep in mind that certain watches, particularly those designed for diving, may require their seals to be replaced along with the battery. This step is crucial for maintaining water resistance.
Avoid attempting to clean or lubricate your watch during the battery replacement process. Work in a clean environment to prevent dust particles from entering the watch mechanism. Even a small drop of lubricant can create enough resistance to damage the delicate watch components and electronics.
If you're unsure about any aspect of the process or your watch's compatibility, it's always wise to seek professional assistance from a watch shop. It's better to be safe than sorry when it comes to the maintenance of your timepiece.
