Secondly, we have Manganese dioxide lithium batteries , which are mostly used by consumer and commercial purposes, and they have the prefix CR and are referred to as a CR lithium battery. The CR series of lithium batteries are cheaper and best when less battery stability is needed. The capacity of a battery is measured in amp hours which is the amount of charge a battery can store. The amount of charge the battery can store is dependent on the mass of active material the cell contains. A typical CR battery has a capacity of mAh.
The button battery will last for about 10 hours when using it with an average load of 24 mA. A typical CR battery has a capacity of 90 mAh.
The button battery will last for about 6 hours when using it with an average load of 15 mA. Simply put, the voltage of a coin cell battery is the measure of the difference in electric potential between the negative and positive terminals.
The typical CR battery is a 3 volt lithium coin battery. This isn't a significant difference, but it is noticeable when looking at the two types of batteries side by side. You can find out the exact dimension of each battery by looking at the four digits in the battery's code. The first two numbers correspond to 20mm in diameter, and the last two digits tell the thickness of each in mm 32mm and 16mm.
The casing of the two types is also a bit different: while both have plastic cases, they are colored differently—silver for CR and white-ish for CR The CR battery has a metal top with ridges that might get in some way on your device.
The actual size of a CR battery is smaller and will fit in more places. But these two types of batteries are best for small devices, such as watches. This slight difference presents another challenge when selecting a replacement if ever you need one in the future. You can't just use one type of coin cell in place of another because their physical dimensions are different.
Do you know why the battery's size has an effect on its lifespan? The thicker a coin cell, the more energy it contains- which equates to long hours of use before needing replacement. This means that if you have an application with high power requirements, such as low-energy flashlights or GPS receivers, then the thicker and longer-lasting CR will be your best option.
A CR battery has a higher capacity where it can last longer before needing to be replaced. CR and CR batteries are both lithium coin cells but not identical at all. Their chemical components will vary slightly to account for what type of function each one is intended for. Therefore, it might not be possible to use a CR battery in place of a CR The physical size difference makes it impossible for the two types of coin cells to work together without some modification.
So if you need to replace either type, then look at the other batteries that are available on the market before making your decision. The CR sometimes called an SR is a kind of button cell battery typically used for watches and some calculators. They are available in two types, primary lithium and silver oxide. Primary lithium is more common for wristwatches, but silver oxide lasts longer, with its higher voltage being suitable for applications that require more time between changes of the batteries.
The most popular sizes for these kinds of batteries are 20mm diameter by 3mm height a very slim one. Using one 1 CR battery to replace two 2 CR batteries might not be the best choice. The voltage of these two batteries is different, and the CR battery has a larger capacity. This could cause your device to have problems from running on an unstable voltage or could not last as long because it is being drained too fast for its size.
If you need to replace either of these batteries, then look at other options available in the market before making a decision about which one will work. CR is a type of lithium battery that has been used in many electronic devices such as watches, calculators, and hearing aids. CR is another alternative option to replace your CR as it is also a coin-cell battery and has a slightly higher capacity.
Well, that's the 5 million dollar question. Of course, the names distinguish the attributes of each of these batteries to better differentiate them to you and me. The IEC defines the letters for these batteries, and these three selected batteries actually contain Chromium. The first two numbers denote the diameter of the battery cells. The last two numbers show the thickness or depth of the battery cells.
The batteries in our review actually have different thicknesses:. It is essential to pay attention to the capacity and therefore the thickness of these CR-sized batteries as it determines just how long each different one will last. To power a typical LED light consumes an average of 20 mA of energy. Here is a simple energy consumption calculation to best illustrate this:. The button cell batteries in our comparison review article can be used interchangeably — in theory.
Why is that? While it is true that all three batteries generate the same voltage, not all devices are compatible to work with batteries that have larger or smaller capacities. The general rule of thumb is to check your devices for battery compatibility before swapping out the battery for a different-sized version. What it means is that while you can physically and mechanically interchange the batteries, you need to proceed with caution and care.
Depending on the replacement button battery installed, the device will enjoy a longer or suffer a shorter service life. By stacking two CR to replace a single CR coin cell battery, a person will effectively yield the same capacity and durability as one CR This is because stacking two CR batteries will produce 6 volts as each battery generates 3 volts to pass through the electrical system of a device designed to handle 3 volts only.
You could indeed use a CR button cell battery to power a device designed for use with a CR battery. In terms of physical and mechanical terms, a CR battery is thinner than a CR This means that the CR will provide percent less battery power in its service life to a device than a CR button cell battery. The voltage and chemical composition of the CR and CR are similar, meaning that the CR will power a device developed for CR battery cells sufficiently.
However, you will need to prepare the battery compartment to better fit and connect the CR battery in this instance. The battery compartment of a device compatible with CR batteries means there is a 0. Still, a person can use an electrical conductor, such as aluminum tinfoil, to fill the 0.
