<p>I buy Maxell brand CR2032s on Amazon. They last years and are cheap, cheap, cheap. I think the last pack I bought was five batteries for $2 including shipping. I don't have to buy them more than once every three years or so. They are lithium.</p>

<p>E = "Energizer" - it's just a proprietary code. Any CR2032 battery is interchangeable.</p>
<p>C = Lithium/manganese-dioxide. This is the chemistry, which defines the power: it's a 3.0V nominal/3.5V pulse discharge battery and they all have essentially the same power supply characteristics.</p>
<p>R = Round. As opposed to square, flat, etc.</p>
<p>20 = 20mm</p>
<p>32 = 32mm</p>

<p>Shelf life will depend upon a number of factors not included in the IEC code. LiMO batteries will lose power while stored but, generally, if you store the things properly you should still have a usable charge for at least 5 years. Each manufacturer will have it's own recommendations.</p>
