Choosing a CR1620 Battery Substitute
Finding a CR1620 battery equivalent is straightforward. You can find this common CR1620 battery under model number
Finding a CR1620 battery equivalent is straightforward. You can find this common CR1620 battery under model numbers like DL1620 and ECR1620. This replacement battery is a safe choice for your small electronic devices. It is a direct replacement for any standard CR1620.
Note: These alternative models are not different batteries. They simply represent brand-specific names for the same CR1620 battery, sharing identical voltage and dimensions.
Knowing these names makes finding a replacement for your CR1620 simple, ensuring your devices have the correct power. This battery has many common uses.
Key Takeaways
- CR1620 battery substitutes like DL1620 and ECR1620 are the same battery with different brand names.
- Always match the battery's size (16mm x 2.0mm) and voltage (3V) to avoid device damage.
- The 'CR' in CR1620 means it is a round lithium battery, which gives stable power.
- Avoid using batteries like CR1616 or silver-oxide types; they are not safe substitutes.
- Check your device's manual or the old battery for the correct model number before buying a replacement.
Understanding the CR1620 Battery
To choose the right substitute, you first need to understand the original CR1620 battery. This small but powerful lithium coin cell has specific characteristics that are vital for your device's performance and safety. Knowing these details helps you see why sticking to exact equivalents is so important.
Key Specifications
The numbers in the name "CR1620" tell you its size, but other specifications are just as crucial. A standard CR1620 battery has a consistent set of features across all reputable brands.
| Specification | Value |
|---|---|
| Chemistry | Lithium Manganese Dioxide (Li-MnO₂) |
| Voltage | 3 Volts |
| Diameter | 16.0 mm |
| Height | 2.0 mm |
| Capacity | 70-100 mAh |
| Operating Temp. | -30°C to 70°C (-22°F to 158°F) |
This wide operating temperature range makes the CR1620 a reliable power source for devices used in various climates.
Why Size and Voltage Matter
You might think a slightly different battery could work in a pinch, but size and voltage are not flexible. Using the wrong battery can cause serious problems.
A CR1620 provides a steady 3 volts. Supplying incorrect voltage can damage your device's sensitive circuits. This may lead to erratic behavior, overheating components, or even permanent failure. Always match the 3V requirement.
The physical dimensions (16mm x 2.0mm) are equally important. A battery that is too thin may not make proper contact, causing the device to fail. A battery that is too thick can put pressure on the device's internal parts, potentially deforming the case or damaging the circuit board.
The 'CR' Naming Convention
The letters in a battery's name provide useful information. According to the International Electrotechnical Commission (IEC) standard for button cell batteries, the "CR" in CR1620 stands for:
C - Indicates its Lithium chemistry. R - Indicates its Round (cylindrical) shape.
This lithium chemistry is a key feature. A lithium CR1620 battery maintains a stable voltage output for most of its life. This is different from alkaline batteries (often labeled 'LR'), which show a gradual voltage drop as they are used. The consistent power from a CR1620 is essential for the reliable operation of electronics like digital watches and medical devices.
Your Guide to the CR1620 Battery Equivalent
Now that you understand the CR1620 battery, you can confidently find a substitute. Choosing the correct replacement is crucial for your device's health and performance. This guide will show you the safe equivalents and warn you about the risky ones. Following this advice helps you select the right cr1620 battery equivalent every time.
Direct Equivalents: The Safe Bet
You will find that several model numbers are direct replacements for the CR1620. These are not different types of batteries. Instead, they are brand-specific names for the same 3V, 16mm x 2.0mm lithium coin cell. Any of these models will serve as a suitable replacement.
The most common replacements you will see are:
- DL1620
- ECR1620
- LM1620
- BR1620
While most of these use the same Lithium Manganese Dioxide chemistry, some variations exist for specific applications. For example, the "BR" prefix indicates a Carbon Monofluoride Lithium battery, which offers excellent long-term reliability and a wider operating temperature range, making it ideal for memory backup.
| Battery Type | Chemistry | Common Use |
|---|---|---|
| CR1620 | Lithium Manganese Dioxide | General Purpose |
| BR1620 | Carbon Monofluoride Lithium | High Temperature, Memory Backup |
| LiR1620 | Rechargeable Lithium-Ion | Specialized Rechargeable Devices |
For most consumer electronics, the standard CR1620 or its direct equivalents (DL1620, ECR1620) are the best replacement.
Common Manufacturer Model Numbers
Major battery brands use their own model numbers for the CR1620 battery. Knowing these names makes shopping much easier. However, you should remember that performance can differ slightly between brands.
It is important to note that CR1620 equivalents may differ slightly in terms of performance characteristics such as capacity, discharge rate, and operating temperature range, even though the size and voltage specifications are identical. For optimal performance, you should also choose a reputable brand since different manufacturers produce batteries with different quality standards.
Here are some of the most popular brands and the model numbers they use for the CR1620 battery equivalent:
When you search for a replacement, looking for any of these brands will lead you to the right cr1620 battery equivalent. Always check the packaging to confirm the battery is a CR1620 or one of its direct equivalents.
Risky Substitutes to Avoid
Using a battery that is not a direct equivalent can cause poor performance or even damage your device. You must avoid batteries with different sizes or voltages.
Size is Not Negotiable A common mistake is grabbing a battery with a similar diameter but a different thickness. The CR1616 is a perfect example.
| Specification | CR1616 | CR1620 |
|---|---|---|
| Diameter | 16.0 mm | 16.0 mm |
| Height | 1.6 mm | 2.0 mm |
| Voltage | 3 Volts | 3 Volts |
The CR1616 is 0.4mm thinner than the CR1620. This small difference is enough to cause the battery to fit loosely in the compartment. A loose fit leads to poor electrical contact, causing your device to flicker or fail. Conversely, trying to force a thicker battery like a CR1625 into a CR1620 slot can bend contacts or crack the device's casing. Never use a much larger battery like the CR2032.
Chemistry Matters You might also see silver-oxide batteries with a similar size, like the SR1620. While a lithium CR1620 battery can sometimes replace a silver-oxide battery, you should not do the reverse. A lithium CR1620 lasts much longer and provides more stable power, making it the superior choice for devices designed for it. Sticking to the recommended CR1620 or its direct lithium equivalents is always the safest and most reliable option.
