When you are in the market looking for coin batteries, you are likely to encounter two major options; cr1632 vs cr1620. Given an option, which one will you go for?
Well, it may be difficult to differentiate the two just by looking at them. But in reality, they are very different. In this guide, we are going to dissect the differences between cr1632 and cr1620.
What is CR1632 battery?
CR1632 is a lithium 3V coin cell battery, also known as a silver oxide battery. It is a small round-shaped battery with a diameter of 16mm and a height of 3.2mm. Also, it weighs only 2 grams.
CR1632 batteries are used in a wide variety of applications like clocks, calculators, hearing aids, and toys. They are also used in emergency lighting systems for aircraft, spacecraft, submarines, and other vehicles that need a backup power source for critical electronic devices in the event of failure of a primary power system.
Cr1632 batteries are available in two physical sizes; standard and high capacity. Standard size cr1632 has a capacity of 100mAh while high capacity cr1632 has 160mAh capacity which is twice that of standard size cr1632 batteries.
What is CR1620 battery?
Well, this is another coin battery, but not quite like the cr1632. It is a lithium 3V coin cell battery, also known as a silver oxide battery. It is a small round-shaped battery with a diameter of 16mm and a height of 2.0mm. Also, it weighs only 1 gram.
Cr1620 batteries are used in a wide variety of applications like toys, small electronic devices, calculators, and hearing aids.
The cr1632 is the same size as the 1632 but it is higher than 1632 by 0.2mm. This means that if you want to fit a 1632 battery into an electronic device designed for a 1632 battery, then you will have to make sure that you are using one with 0.2mm more height than the original one, or else it won’t fit in properly.
Features of cr1632 battery
Now, let’s look at the key features that make up, or characterize the cr 1632 battery.
-Non-rechargeable: This battery is not rechargeable. This means that the battery cannot be recharged once the power is used up. It must be replaced after use, while the other types of batteries can be recharged to use again.
-Long lasting: The cr1632 has a long shelf life, and it can last for years without losing its charge.
-Lightweight: The cr1632 is lightweight, weighing only 1 gram and having a diameter of 16mm and a height of 2mm.
-Nominal voltage of 3V: This battery has a nominal voltage of 3V, meaning that it can hold up to 3V charge.
-Low self-discharge: The cr1632 has a low self-discharge rate, which means that it takes a long time for the charge to wear off after you have removed it.
-Peak battery capacity of 130mAH: This simply means that the cr1632 can hold up to 130 milliamp hours of power.
-Peak drain current of 6.8mA: This is the peak current that can be used by the cr1632, and it is 6.8 milliamps.
-Chemistry: This battery is composed of lithium manganese dioxide cathode and carbon anode.
-Memory effect: The cr1632 has a memory effect, which means that the charge level of the battery keeps on decreasing even if the power has not been used for a long time. However, this effect can be mitigated with regular use.
-Lithium-ion technology: The cr1632 uses lithium-ion technology for its construction and operation, which means that it uses lithium ions instead of chemical reactions to generate electricity.
-Constant current output: The cr1632 has a constant current output, meaning that it will always produce a constant amount of charge no matter how much power is put into it.
Viable alternatives that you can use in place of CR1632 coin battery include ECR1632 and DL1632. Both of these batteries have the same voltage and capacity. So, in terms of the performance, you are likely to experience minimal difference.
The only difference between these batteries may be in terms of cost. The ECR1632 is sold at a lower price, but the DL1632 is slightly more expensive.
Features of cr1620 battery
-Nominal voltage of 3V. This means that the cr1620 can produce 3 volts of power.
-Nominal capacity of 120mAh. This means that the cr1620 can hold up to 120 milliamp hours of power.
-Peak drain current of 6.8mA: This is the peak current that can be used by the cr1620, and it is 6.8 milliamps.
-Chemistry: The cr1620 battery is composed of lithium manganese dioxide cathode and carbon anode.
-Memory effect: The cr1620 has a memory effect, which means that the charge level of the battery keeps on decreasing even if the power has not been used for a long time. However, this effect can be mitigated with regular use.
-Lithium-ion technology: The cr1620 uses lithium-ion technology for its construction and operation, which means that it uses lithium ions instead of chemical reactions to generate electricity.
-Non-rechargeable: This means that the cr1620 can not be recharged. It can only be used once before its full capacity is depleted.
-Low self-discharge: The cr1620 has a low self-discharge rate, meaning that it will retain its charge for a long time even when it is stored in a place with low temperature.
-Efficiency: The cr1620 is quite efficient, which means that it has a high energy density and output power per gram.
-Stable voltage: The cr1620 has a stable voltage output, which means that the battery will not fall short of its voltage output even if there are no current sources to provide power to the battery.
CR1620 battery alternatives
Which equivalent batteries can I use in place of the CR1620? You may ask.
Some viable options that you should consider purchasing include ECR 1620, DL1620,5009LC, and SBT-17. All these options are close in terms of price, capacity, voltage, and discharge rate. They may only vary in terms of performance.
CR1632 vs CR1620: What’s The Difference?
Now, let’s dissect the differences between these two batteries based on their features and characteristics.
From the features, it is clear that the two batteries have the same nominal voltage, that is 3V. If the voltage of a battery is your main concern, you can go for either of the batteries and they will serve their purpose to the fullest.
Battery current capacity
Battery current capacity refers to the amount of current that can be drawn from a battery. The cr1632 has a maximum current capacity of 130mAh, while the cr1620 can handle only up to 68mAh of current.
As mentioned above, the CR1632 has a low self-discharge rate and will retain its charge for a long time even when it is stored in a place with a low temperature. The CR1620 has a much higher self-discharge rate and will lose its charge in as short as 6 months if it is stored in a place with high temperature or humidity for a long time period. So if you are looking for extended shelf life for your battery, go for CR1620 and not CR1632.
The weight difference between the two is very small such that you won’t even notice. CR1632 battery weighs 1.8 grams while CR1620 weighs 1.2 grams. In general, both the batteries are lightweight. This means that if your application is weight-sensitive, you can easily go with either of these coin batteries.
CR1632 and CR1620 have the same dimensions or diameter. Both are 2mm thick and have a diameter of 16mm. This means that CR1620 will fit in almost all the gadgets that accept CR1620 batteries.
Both the CR1632 and CR1620 are Lithium-based batteries. Lithium is an alkaline-like element that can store an electrical charge. Lithium is one of the most common elements in the universe and is present in many different compounds. CR1632 battery contains Lithium Manganese dioxide while CR1620 contains Lithium iron phosphate. However, both these batteries have a nominal voltage of 3 volts.
Since these two batteries have many similarities, you should expect the same when it comes to their application areas. These are widely used in all the gadgets that require coin-type batteries. In fact, CR1632 is one of the most preferred batteries for small electronics. It is used in a wide range of toys and other small appliances such as watches, calculators, hearing aids, clocks, etc.
Both CR1620 and CR 1632 are non-rechargeable batteries. That means that you have to buy new batteries for your gadgets. You can recharge them by using a charger or recharging station.
The cost of CR1632 is higher than CR1620 but the difference is not significant. Though CR1632 is more expensive than CR1620, it is still a very cheap and affordable battery for your small electronics and appliances. The cost of CR1632 is approximately US$0.70 whereas the cost of CR 1620 ranges between US$0.60 to US$ 0.80 per piece depending on where you buy them from and shipping charges as well as handling charges.
Of course, the price will always depend on where you buy the batteries.
