Higher capacity, which will lead to a longer life. Perfect for watches, heart monitor scans, and hearing aids. For as long as either fits in the battery compartment, the CR and CR can be used interchangeably with minimal effect, although the CR is likely to last slightly longer simply because it has a higher capacity mAh.
Here's a tip: if you're in a pinch with only the CR available, you can fold up a piece of aluminum foil or another conductor to fill up the 0. Ensure good contact with the battery and the spring otherwise there is a risk that the battery will be intermittent. Another good way to explain the similarity and difference between the batteries CR and CR is by looking at their names and understanding the code used by the International Electrotechnical Commission IEC to name these batteries.
The combination of letters and numbers used to name the batteries is not arbitrary. It tells you a lot about the physical attributes of the battery. The two letters tell you about the chemistry of the battery. C means it's a manganese lithium dioxide battery. R indicates the round cylindrical shape.
The first two numbers concern the diameter of the battery, while the last two numbers relate to the depth of the battery. It is essentially said along these lines that the CR has a diameter of Iggy 23 Feb In detail, it is a high speed JFET input dual operational amplifier.

CR vs CRThe Important Difference Between the CR Battery and the CR Battery One of the most common questions that we receive from our Microbattery customers is how to determine the correct battery to use for a particular device when presented with battery options that have similar characteristics.
The C in CR lets you know the battery uses a lithium chemistry. The R lets you know that the battery is round in shape. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. So by following this, you can easily see that a CR battery is a C lithium chemistry battery with a R round shape that has a diameter of 20 20 millimeters and a height of 32 3.
This applies to the majority of coin and button cell batteries but note there are some exceptions, like the CR2 or CRA batteries which are considered lithium cylindrical batteries.

Battery Naming Standards, Certifications, and Terms. Connect and share knowledge within a single location that is structured and easy to search. A is 20mm in diameter, 3. They usually both have the same voltage 3V , and assuming they fit in the case, they are interchangeable. For my scale, I accidentally bought a pack of thin batteries instead of the thicker ones.
Is there another way to get it to work with just one wrong thin battery? Feeding it 6V can't be good for it. The difference is therefore 0. While many folds of aluminum foil will no doubt work, my preference would be to use a dime for best conductivity and to keep the battery secure from moving under the spring.
Since he has been using two CR batteries bad plan on several levels - stressing out the spring and the voltage regulation circuit as the two biggest problems , we can be sure that one CR plus a dime will fit in the space. But now that the spring is stretched out guessing Likely but maybe not , a penny might be better in his case.
The reason two cells worked in your scale is that the scale is internally regulated to compensate for voltage drop as the battery runs down. If the scale worked with two of the cells, there's no reason to expect it'll suddenly stop working or sustain damage -- if that were going to happen, it would have happened either immediately on inserting the cells, or as soon as the device powered up.
That said, a spacer for the dimensions you give, a US or Canadian five cent coin might work on the flat end of the cell is preferred over a second cell. If you're trying to substitute a thinner cell in a device that hasn't previously been tested, this will ensure you get the correct voltage and avoid the risk of damaging the device. Worth noting that using 6V instead of 3V with cells this size poses no hazard other than possible damage to the device.
There isn't enough current available from this type of cell to start a fire short of a device specifically designed to do so or produce a shock you can even feel except on your tongue, or again with a device specifically designed to step up the voltage. With much larger cells say, the size of those that make up a car battery or radio control model power pack , there's a slight possibility of fire or burns, but even then, 6V won't give a shock you can feel on dry skin likely not on damp skin, either.
In this sort of situation, I normally use aluminium foil. It can be folded the required number of times to achieve the 0. If it's too thick, unfold, cut some off and re-fold. Having a continuous strip ensures that there is always a path from one face to the other, regardless of the inevitable gaps between layers. At the moment, you are relying upon a little spring to compensate for the extra 1. In my experience, these springs aren't that good and you may have already caused it to lose the ability to properly connect with a battery in the future.
You might be able to bend it back again, but it will be difficult. First you are lucky if your scale still works. Doubling the voltage as you described by putting them in series can kill it. This is not advisable as it's dangerous to use electrical equipment with anything else than what their user manual mentions.
However for a short term use, depending on holder shape and terminals you can fold some aluminum foil tightly until you get proper thickness with the battery on positive side. Be careful not to short the connections of the holder as there's risk of fire.
