What makes a good CR2032 Battery?

CR2032 batteries are referred to as a lithium coin cell. They are interchangeable with all models with the preceding 2032 name. The name is derived from the dimensions of the battery, being 20mm x 3.2mm. Lithium batteries are much more suited for high drain devices as opposed to their alkaline couterparts.

Capacity – The standard capacity of a CR2032 battery is 225mAh but this could be higher or lower depending on the manufacturer and also the age of the battery. The milliampere-hour may also vary slightly from battery to battery. For instance energizer panasonic CR2032 has a stated capacity of 225mAh whereas an energizer has 235mAh. This determines the amount of energy the battery has.

Voltage – CR2032 batteries are rated at a standard 3V (three volt). Testing the batteries may produce differing results. This is due to age and also manufacturing process. Testing a fresh CR2032 should yield a result of 3V but slightly higher or lower is normal.

Operating Temperature Range – All brands of CR2032 battery are very tolerant to extreme temperatures out of the normal operating range. The standard range is -20 degrees C – 60 degrees C. Some brands have a wider operating temperature but depending on your application or device you may want to check the datasheet of the specific manufacturer to determine the best suited battery for your needs.

Long Shelf Life – Lithium coin cell batteries are well known for their long shelf life. Often exceeding 10 years are 80% capacity. Batteries are best stored in a dry cool place in the recommended operating range. Keep batteries away from damp and wet areas including very humid basements and attics. The extreme temperature change will eventually degrade the batteries longevity.

No Leak Design – CR2032 batteries are encased in a stainless steel enclosure and pose very little risk of leaking. Only batteries stored in sub optimal conditions will degrade enough that they may leak. If a battery has been left in a damp or wet place and you are concerned then dispose of it appropriately.

CR2032 Battery FAQ

Q: Is a CR2032 battery rechargeable?

A: A CR2032 battery non rechargeable coin shaped battery. The rechargeable equivalent of a CR2032 battery is called the BR2032 battery. These are a very uncommon battery. Definitely do not try to charge a standard CR2032 as this could cause a fire.

Q: What is the difference between a CR2032 and CR2016 battery?

A: CR2032 battery dimensions are 20mm x 3.2mm whereas the CR2016 battery is half the height registering at 20mm x 1.6mm. This essentially means that two CR2016 batteries can be used to replace a single CR2032 battery. This is not recommended but for a short term solution this will work fine. Capacity of CR2016 is much smaller than CR2032 so don’t use this a long term solution.

Q: What is the difference between a CR2032 and CR2025 battery?

A: As noted above the only difference between these batteries are the physical dimensions and the capacity. CR2025 has dimensions of 20mm x 2.5mm. These cannot be used to replace a CR2032 without some insert to negate the empty space.

Q: Are CR2032 and CR2025 batteries interchangeable?

A: Not exactly. See the above answer.

Q: How do you dispose of CR2032 batteries properly?

A: Because oCR2032 batteries contain dangerous chemicals it is essential to dispose of them properly. Most states and countries have specific rules governing the disposal of lithium batteries. Definitely do not dispose of them with your regular trash. Even if the contacts are separated they could pose a fire risk. Google your state+county to check for local ordinances regarding lithium battery disposal. Most localities have a designated battery recycling drop off location.

Q: How long do CR2032 batteries last?

A: As discussed earlier CR2032 batteries have a shelf life of between 5-10 years if stored correctly. The power your device uses will determine how long the CR2032 will last.

Q: Which is the best quality CR2032 battery?

A: This is not an easy answer. Depending on your use the answer will vary. Sony, energizer, Maxell and Panasonic are all big brand names but this does not mean the little guys are producing lesser quality batteries. Check datasheets and manufacturer websites.

Q: Is a DL2032 and CR2032 the same?

A: Yes they are interchangeable. Duracells designated name for the CR2032 is DL2032. Duracell does this with most naming conventions on their batteries. Using the DL prefix.

Q: What does the CR stand for in CR2032?

CR means it’s a lithium primary (non-rechargeable) battery.  “CR” is the chemical representation of chromium.

Q: Where to buy CR2032?

A: Well this answer is easy. See our full selection of CR2032 batteries.

Q: When to replace a CR2032 battery?

Once your device requires a certain voltage and the CR2032 no longer has enough capacity to maintain this voltage then the device simply stops working. This is when to replace a CR2032 battery.
