Lithium CR2032 3V battery is primary coin cell battery, while LIR2032 battery is very similar 3.6V lithium rechargeable coin cell battery. The CR2032 battery is mainly used in many small devices and gadgets as  its main features include:

  • Small dimensions
  • Wide temperature range
  • Large capacity
  • Low self-discharge rate
  • And long shelf-life.

The BR2032 is very similar to the CR2032m, except it uses carbon monofluoride as positive electrode, instead of manganese dioxide, which is found in the CR2032.

The Lithium CR2032 3V battery is a primary coin cell battery, while the LIR2032 battery is a very similar 3.6V lithium rechargeable coin cell battery.

The IEC standard 60086 defines the 2032 battery as a round cell with 19.9 (±0.1 mm) in diameter and 3.1 (±0.1 mm) in height – 2032 actually means 20 mm in diameter and 3.2 mm in height.

Depending on the model and manufacturer, 2032 batteries weigh around between 3.0 g and 3.2 g.

2032 Batteries Specifications and Comparisons

Main CR2032 characteristics

  • Typical capacity: around 225 mAh
  • Nominal voltage: 3.0V
  • Cutoff voltage: 2.0V
  • Operating temperature: between -20°C (-4°F) and 70°C (158°F)
  • Positive electrode: manganese dioxide
  • Shelf Life: 10 years (at least for models from reputable manufacturers!)

Main BR2032 characteristics

  • Typical capacity: 190 mAh
  • Nominal voltage: 2.8V
  • Cutoff voltage: 2.25V
  • Operating temperature: between -30°C (-22°F) and 85°C (185°F)
  • Positive electrode: carbon fluoride
  • Shelf life: longer than in the CR2032

Main LIR2032 characteristicsGeneric LIR 2032 3.6V battery

  • Typical capacity: 40 mAh
  • Nominal voltage: 3.6V,
  • Cutoff voltage: 3.0V,
  • Recommended charging temperature: between 0°C (32°C) and 45°C (113°F)
  • Recommended discharging temperature: between -20°C (-4°F) and 60°C (140°F)
  • Minimum number of charging/discharging cycles: at least 300-500

The CR2032 battery can be replaced with a BR2032 battery without the danger of damaged electronics and in most cases, devices will work properly.

However, the CR2032 and BR2032 SHOULD NOT be replaced with a LIR2032 battery due to voltage differences – 0.6V doesn’t sound much, but it is enough to make the damage.

Before replacing a CR2032 or BR2032 battery with a LIR2032 check the device manual or contact the device manufacturer directly.

Note: The DL2032 battery is a CR2032 battery produced by Duracell, while the ECR2032 battery is a CR2032 battery produced by Energizer etc. Also note that manufacturers use both CR2032 and custom designations.

In high-end and/or robotic vacuum cleaners, if CR2032 batteries are present, they are used as motherboard batteries as they can hold the charge for many years and keep the CMOS memory functioning properly.

LIR2032 batteries, on the other hand, have very high self-discharge rates when compared with the CR2032 and BR2032 batteries and there is really no need to use them in vacuums as CMOS support or for similar functions.

If you do require new CR2032 batteries, for a vacuum cleaner or some other device, consider buying batteries from reputable sellers and manufacturers. Generic batteries may be cheap but saving a few dollars now may cause numerous headaches later.

The most popular manufacturers of 2032 batteries, along with their best models are given in the table below.

There are many other manufacturers and packages, but these 5 CR2032 battery packs have average user ratings of at least 4.5 along with tens, even hundreds of positive reviews from real purchasing customers.

We haven’t mentioned any BR2032 or LIR2032 in our chart. BR2032 batteries’ wider temperature range is not so important for vacuum cleaners (who have inner home temperatures of below -20°C?) and LIR2032s have unacceptable self-discharge rate when compared with CR2032s to be used in vacuum cleaners, laptops, calculators and similar devices.

A LIR2032’s price vs. a CR2032’s price: A quality CR2032 battery is as expensive as a quality LIR2032 battery – or it costs even more!

However, if you are looking for good LIR2032 batteries with charger, Zackees Rechargeable USB Coin Cell Charger with 2 provided batteries or CT-ENERGY Lithium Ion 2032 Battery Charger with four LIR2032 batteries.

Both are nice sets that come at a reasonable price.

The capacity of these batteries is on average around 35-40 mAh (CR2032 200-225 mAh), but they can handle a discharge rate of about 70 mA, while the CR2032’s max burst discharge rate is around 15-16 mAh.

Again – LIR2032 batteries have 3.6V, while CR2032 3V. Unless you are absolutely sure that your device can handle this increase in voltage, DON’T use LIR2032 batteries instead of CR2032 batteries

Such (small) increase in voltage may damage or make a device act strangely to say the least.
