LIR2032 Li-ion Battery 3.6 V Battery LIR 2032, 3.2 x 20 mm.

Product Information

The longest lasting CR2032 battery that we sell is the Duracell Procell CR2032. Review after review, comparison after comparison, the Duracell Procell CR2032 comes out on top. Where can I buy all the 2032 type batteries I need?

The BR2032 is a 3-volt lithium battery with a nominal capacity of 200 mAh. It is a non-rechargeable and continuous drain current of 0.03 mA. The BR2032 is ideal for powering CMOS circuits, or any other type of circuit requiring a low voltage and a constant drain current. It is also very compact and can be used as a stand-alone power source for smaller projects. What is an ML2032 Battery?Note that all three types of 2032 batteries are some form of lithium battery, as lithium is combined with other chemicals in their makeup. This does mean that every lithium battery is created equal. Anyway several threads over the years demonstrated, as you hint, that non-rechargeable cells last longer in the field than rechargeable so no point in the latter. However I think the reason chinese started sending them with CR2032 instead of LIR2032 had more to do with cutting cost than long term reliability. The DL2032 battery is a coin cell non-rechargeable, rewritable and reusable battery with an average capacity of 225mAh and 3V of power. This is a great battery for people who are looking for a reliable power supply for their mobile devices. You can use it to power a variety of devices including smartphones, digital cameras, MP3 players, GPS devices, tablet computers, e-readers, wireless headsets, PDAs, and many other devices. This battery is also very affordable, making it a good option for those on a budget. What is a BR2032 Battery? The supplied coin cell will last up to ten years and most DS3231 boards won't have a charging circuit for any form of rechargeable.

Actually 99% of the DS3231 modules sold do have a charging circuit (diode and resistor) and that is not a Good Thing. Originally all the modules were shipped with LIR2032 which is why that was part of the design. Unfortunately the values are wrong and tend to destroy rechargeables and primary cells never accept this abuse at all and fail even sooner. Those in the know immediately remove one of the components or increase from 200r to 100k or so to avoid this. The three coin cell batteries we’ll be examining each have their own chemical make-ups for their positive cathodes. Let’s look at them now. CR2032 Battery Chemistry We’ll begin with a brief overview of coin cell batteries in general, and then go into each type of 2032 battery in some detail. By the time we’re finished, we’ll have made your day easier, I promise.
