几乎每个人都熟悉典型的碱性电池的尺寸，例如AA，AAA，D等。但是，他们更离散的表亲，即硬币电池电池，仅仅看着它们就可以分开一点一点，而且它们似乎都有一些奇怪的数字和字母的奇怪的密码。不用担心！这篇文章将使您可以快速了解如何翻译所有balderdash。
On coin cell batteries you’ll find a code that consists of two letters, followed by four (sometimes three) numbers. This particular naming convention conforms to the current International Electrotechnical Commission (IEC) standard, though there are coin cells that conform to an older standard and are named differently.
The first of the two letters is used to indicate what type of battery it is. The second letter, the R, is just an indicator of the shape (cylindrical). The various chemistries are listed below in cathode/anode (+/-) order. (The lithium batteries here are not rechargeable lithium-ion, they just contain lithium)
- B - 碳单氟化物/锂
- C – Manganese-dioxide/Lithium
- G – Copper-oxide/Lithium
- L - 锰二氧化锰/锌
- M，N - 汞/氧化物/锌
- P – Oxygen/Zinc (zinc-air battery)
- S – Silver-oxide/Zinc
The numbers following the first two letters are an indication of the battery’s dimensions. Diameter in millimeters is indicated by the first two, in a four digit code, or just the first in a three digit code. The last two numbers indicate the height of the battery in tenths of a millimeter.
As you can see (allowing for some manufacturing tolerances for the dimensions) the size indicated on the battery is pretty spot on 20mm wide and 1.6mm tall. Well, that’s about it, folks. Now you can amaze your friends at parties by telling them what coin cell battery codes mean……or not.
Hey, FYI… when you stack coin cells, you risk having a bunch of dead batteries, or worse, melting the box they are in :-).
You missed out few letters in your explanation. Even the batteries in you photo are CR and four digits. The C (according to your explanation means manganese-dioxide/lithium), but what’s the R? The battery I’m holding is a DL 2025 which I’m guessing is manganese-dioxide/zinc based on your description. But what’s the D? Is that for Duracell? It’s a Duracell battery. Is a DR2025 interchangeable for a CR2025?
我必须在门铃中更换硬币电池，它说3V锂，并在背面有1411的数字，购买另一张锂时我要寻找什么？
谢谢
I have two button batteries LR1130 and A66 for my calculators what shall I look when buying another?
The R, I think he mentioned earlier in the post, was the description of the shape of the battery. So R, I’ll assume, would stand for “round”. As for the D, I even double checked before answering, so I can definitely say yes, it does stand for Duracell. So yeah, so long as the sizes are the same (20 mm in diameter and 2.5 mm in hight), they’ll be interchangeable, even if the first letters are different, cuz that’s only telling what the battery was made with so unless it’s a specialized piece using the battery and requires specific battery types right down to the mixture in the battery, you’ll be good to go.
What about voltage? Your picture shows a 3v battery.
Others measure 1.55v.
