Lithium CR2032 3V battery is primary coin cell battery, while LIR2032 battery is very similar 3.6V lithium rechargeable coin cell battery. CR2032 battery is used in many small devices and gadgets – its main features are small dimensions, wide temperature range, large capacity, low self-discharge rate and hence long shelf-life. BR2032 is very similar to CR2032m, except it uses carbon monofluoride as positive electrode, instead of manganese dioxide found in CR2032.

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

IEC standard 60086 defines 2032 battery as a round cell 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 range between -20°C (-4°F) and 70°C (158°F), positive electrode – manganese dioxide, 10 year shelf life (at least models from reputable manufacturers!).

Main BR2032 characteristics: typical capacity 190 mAh, nominal voltage 2.8V, cutoff voltage 2.25V, operating temperature range between -30°C (-22°F) and 85°C (185°F), positive electrode – carbon fluoride, shelf life longer than in CR2032.

Main LIR2032 characteristics: 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 is, at least, 300-500.

CR2032 battery can be replaced with BR2032 battery without the danger of damaged electronics and in most cases, devices will work properly. However, CR2032 and BR2032 SHOULD NOT be replaced by LIR2032 battery due to voltage difference – 0.6V doesn’t sound much, but it is enough to make the damage. Before replacing CR2032 or BR2032 batteries with LIR2032 check the device manuals or contact the device manufacturer directly.

Note: DL2032 battery is CR2032 battery produced by Duracell, ECR2032 battery is 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 – they hold the charge for many years and enable CMOS memory to function properly. LIR2032 batteries have very high self-discharge rate when compared with CR2032 and BR2032 batteries and there is really no need to use them in vacuums as CMOS or similar batteries.

If you do require new CR2032 batteries, for vacuum cleaner or some other device, consider buying batteries from reputable sellers and manufacturers – these batteries are relatively cheap and saving few dollars/euros can cause headaches latter.

Most popular manufacturers and their models of 2032 batteries are given in the following table:

There are many other manufacturers and packages, but these 5 CR2032 battery packs have average rating of at least 4.5 and tens, even hundreds of real life votes. So, they must be good 🙂

We didn’t mention any BR2032 or LIR2032 – BR2032 wider temperature range is not so important for vacuum cleaners (who has inner home temperature of below -20°C?) and LIR2032 have unacceptable self-discharge rate when compared with CR2032 to be used in vacuum cleaners, laptops, calculators and similar. LIR2032 price vs. CR2032 price – good CR2032 battery is as expensive as good LIR2032 battery – or it costs even more!

Check Price

However, if you are looking for good LIR2032 batteries with charger, Zackees Rechargeable Coin Cell Charger with two LIR2032 batteries is nice set that comes at acceptable price. The capacity of these batteries is on average around 35-40 mAh (CR2032 200-225 mAh), but they can handle discharge rate of about 70 mA, while CR2032 max burst discharge rate is 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 increase in voltage can make damage or make a device act strangely, to say the least.
