A button cell, watch battery, or coin battery is a small single-cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high — resembling a button.
lithium batteries
Most of the lithium batteries you’ll see are in coin/button cell form. Coin cells are small discs (see above), often Lithium cells are used (3V) but Alkaline, zinc air, and manganese are also used (1.5V). They are very small and very light, great for small, low-power devices.
Coin lithium batteries. You may know them as button batteries. These little silver-colored batteries power everything from toys and electronics to watches and musical greeting cards.
Button batteries are made from a variety of chemistries, including silver oxide, alkaline, lithium, and zinc air. Not to mention, that some button and coin cells are rechargeable, so depending on the product, a rechargeable battery may be the best choice for you.
Some are alkaline, others are lithium. Alkaline coin cell batteries have a nominal voltage of 1.5V. Lithium coin cell batteries, on the other hand, have a nominal voltage of 3V.
Is CR2032 a lithium battery?
Coin Lithium – CR2032. Panasonic Lithium coin CR2032 batteries is the most common battery coin providing long-lasting, reliable power for various devices. They are used to power small electronics devices such as calculators, wrist watches, various medical devices, fitness appliances, toys etc.
Which batteries are lithium?
Lithium batteries are primary batteries that have metallic lithium as an anode. These types of batteries are also referred to as lithium-metal batteries. They stand apart from other batteries in their high charge density and high cost per unit.
Button batteries can be found in many places around your home:
- Remote controls.
- Thermometers.
- Games and toys.
- Hearing aids.
- Calculators.
- Bathroom scales.
- Key fobs.
- Watches and electronic jewelry.
What type of battery is a CR2032?
lithium-ion battery
The ubiquitous CR2032 battery is a coin-shaped three-volt lithium-ion battery. This class of battery has a diameter of 20 mm and a thickness of 3.1 mm, with some slight variations.
The button cell batteries differ according to their chemical composition, voltage capacity, ability to charge, and sizes. In this category, alkaline batteries have the same sizes as others but offer less capacity and less constant voltage than the costly silver oxide and lithium cells.
CR2032: lithium, 20 mm diameter, 3.2 mm height, 220 mAh. CR2032H; lithium, 20 mm diameter, 3.2 mm height 240 mAh. CR2025: lithium, 20 mm diameter, 2.5 mm height, 170 mAh.
Package size.
| Number code | Nominal diameter (mm) | Tolerance (mm) |
|---|---|---|
| 4 | 4.8 | ±0.15 |
| 5 | 5.8 | ±0.15 |
| 6 | 6.8 | ±0.15 |
| 7 | 7.9 | ±0.15 |
Can I replace a cr2032h with a CR2032?
It also refers to the battery’s discharge rate. In this case, the “H” refers to a high discharge rate. The CR2032 also comes in medium (M) and low (L) discharge varieties. I would replace it with the H version even if the price was 3 times as much.
Lithium Coin Cells are small discs that are very small and very light, great for small, low-power devices. They’re also fairly safe, have a long shelf life and fairly inexpensive per unit.
What kind of batteries are 3V?
There are two types of 3V batteries, CR2 and coin cell. CR2 batteries are very similar in shape to regular AA batteries, however they are generally shorter and slightly smaller. They are commonly used in devices like flashlights, remote controls and digital cameras.
What does CR mean on a battery?
Primary Batteries
CR (Heat Resistant Coin Type Lithium Manganese Dioxide Battery)
What size is a 3V battery?
Voltage: 3 V. Dimensions: 0.15-in (L) x 1.7-in (W) x 3.1-in (H).
What’s the difference between BR and CR batteries?
CR type batteries are slightly less robust than the BR type when exposed to temperatures at the high end of the operating temperature range and can experience a rapid increase in self-discharge at the high end of its temperature rating.

How long does a 2032 battery last in a key fob?
The battery may last for 2-3 years in a smart key fob and for 4-6 years in a regular fob with the key.
What is an AGM battery?
Absorbent Glass Mat
AGM or Absorbent Glass Mat is an advanced lead-acid battery that provides superior power to support the higher electrical demands of today’s vehicles and start-stop applications. AGM batteries are extremely resistant to vibration, are totally sealed, nonspillable and maintenance-free.
What is the difference between lithium and lithium-ion?
The difference between lithium and lithium-ion batteries is that one is not rechargeable (primary cell) and the other can be recharged (secondary cell). In addition to this, Lithium batteries have a shelf life up to four times longer than lithium-ion batteries and are also much cheaper and easier to make.
