Difference between lithium battery 2025 vs 2032 - which is better

Every battery-powered device has a designated battery type that is suited and recommended to be used along with it. Battery sizes can be similar and may even look identical but in fact, each battery type is unique with a slight difference in dimension and size. Some of the most common battery types that are easily mistaken for each other like lithium button battery 2025 vs 2032.

Battery 2025 vs 2032 are button batteries often appear in children’s toys, electronic scales, remote controls, counters, electronic dictionaries, computers, cameras, hearing aids and other portable devices, especially used as a watch battery. Generally speaking, there are two types of button batteries, rechargeable and non-rechargeable. The rechargeable ones include 3.6V and 3V rechargeable lithium-ion button batteries.

In this article, we’ll be going through the differences and similarities of common lithium button batteries like a battery 2025 vs 2032, which one has the more advantage.

What is a lithium 2025 battery

The designation “2025” is a serial code given to a type of lithium button battery cell with a 20-millimeter diameter and a 2.5-millimeter thickness. These lithium CR2025 button batteries are non-rechargeable and can only be used for a rated period, after which they need to be replaced. All CR2025 batteries are rated at 3V and normally have a maximum capacity of 170mAh.

The general application of these CR2025 batteries limits them to certain small portable devices which are specifically designed to function within the maximum current/voltage capacity these batteries offer. Some of these devices and applications include small electronics like calculators, watches, garage door openers, toys, and others.

Some of the batteries have also found use in some portable medical devices, pedometers, computer motherboards, pacemakers, and much more. It is important to note that the mounting space designated for the battery on the device must be suited to the shape and size of the CR2025 battery for proper setting and performance.

What is lithium 2032 battery

Much like every other button battery, the designation “2032” is used to identify the lithium button battery with a diameter of 20 millimeters and a thickness of 3.2 millimeters. When comparing button batteries like battery 2025 vs 2032 battery, the CR2032 lithium button battery is slightly thicker and larger than the CR2025 battery.

Although CR2032 is larger than CR2025 both batteries have the same nominal voltage of 3V but as expected, the CR2032 has a slightly larger capacity of up to 240mAh but could be lower depending on the manufacturer’s specifications. Unlike the CR2025 battery, the CR2032 button battery is slightly thicker and as such will need to be paired with applications and devices with sufficient mounting space.

When comparing battery 2025 vs 2032, it is common to use both batteries with the same devices as they share the voltage and relatively similar capacity. With a slightly higher capacity than CR2025 batteries, the CR2032 battery may last longer when used with the same devices and applications. This added capacity is why CR2032 may also be paired with other portable devices such as medical devices and security system panels.

How long do battery 2025 vs 2032 battery last

The duration of any battery and the period at which it can hold a charge depends primarily on the battery chemistry. While other factors like temperature, usage conditions, and storage conditions are important to determine how long a battery lasts, the chemistry of the battery ultimately depends on how well these contributing factors will affect the battery.

When comparing lithium battery 2025 vs 2032 in terms of how long each battery lasts, it is important to note that they are both lithium batteries and are made with high-quality lithium materials. Of course, the rechargeable Li-ion battery 2025 vs 2032 will be more durable and last longer than the non-rechargeable button cell. Each lithium button battery has a high energy density and can retain its primary charge state for long times. Both the rechargeable lithium CR2025 and CR2032 batteries can last for as long as 2-5 years when used under normal usage conditions and proper storage.

What is the difference between lithium battery 2025 vs 2032 battery

In comparing lithium battery 2025 vs 2032 there are obvious similarities as well as some significant differences. The major and most noticeable difference between both button battery types is the size and thickness of each battery with CR2032 being 0.7 millimeters thicker than CR2025. This difference in size may sometimes determine the kind of devices that both batteries can be used with as the required mounting space would need to correspond with the difference in size.

● The battery capacity is different, the former is 210mAh and the latter is 150mAh.
● The battery life is different, and the battery life of the 2025 is relatively long.
● The size is different. The size of the button battery 2032 is larger than that of the 2025.
● The weight is different. The 2032 battery is slightly heavier than the 2025 battery.
● The withstand current is different, the button battery 2025 can withstand the current is 20mA, the button battery 2032 can withstand the current is 10mA

Another major difference when comparing lithium battery 2025 vs 2032 is the capacity rate of both batteries. Due to its slightly larger size, the CR2032 battery has a capacity range of 200-240mAh, which is higher than the CR2025 battery’s capacity range of 140-170mAh capacity. This greater capacity means that CR2032 batteries can be used with devices that draw slightly more current than CR2025 batteries are rated for.

Can you replace the 2025 battery with a 2032 battery

When comparing lithium battery 2025 vs 2032, both batteries can be used interchangeably. A CE2032 battery can be used to replace a CR2025 battery provided the mounting space for the battery is sufficient enough to accommodate the slightly larger CR2032 battery. Also, since the CR2032 battery has more capacity of up to 240mAh than the CR2025 battery, it would definitely last longer under use.

Which is better – lithium battery 2025 vs 2032

In comparing lithium battery 2025 vs 2032 there are more similarities between both battery types than there are differences. Both batteries are rated 3V lithium button battery cells and both batteries have a diameter of 20 millimeters. Both batteries are also used interchangeably with the same applications and devices. But most people commonly prefer the battery CR2032 vs CR2025 due to the larger capacity of CR2032 which also means the CR2032 battery lasts a lot longer when in use.

Each type of battery has its own dominant application field. For example, generally 2032 batteries are used more on computer motherboards, and 2025 batteries are more used on car keys. It is best to choose the right one. But if you look at the performance of the battery, it must be the capacity and duration of the 2032 battery, and the current tolerance is more advantageous.

How to dispose of lithium battery 2025 and 2032

If zinc electrodes are used in alkaline batteries, silver oxide batteries, and zinc-air batteries, the zinc in the negative electrode and the components in the electrolyte can react chemically to cause expansion, and a small amount of mercury is usually coated on the zinc surface, but it also causes waste. Mercury pollution caused by batteries to the environment and need to be disposed of in hazardous waste.

Unlike other battery chemistry types, lithium batteries are free from harmful toxic chemicals that may pose an environmental threat if disposed of improperly. In essence, when comparing lithium battery 2025 vs 2032 both batteries are free from chemicals like cadmium and mercury and hence can be disposed of as dry waste or simply taken to a battery recycle station for recycling. This is one of the reasons why lithium-ion batteries are better. For details, please refer to lithium battery vs other batteries.

There is one thing to remind, button batteries cannot be in contact with each other when storing or disposing of them, as brief contact may cause leakage， because the positive and negative poles of the button battery are close, it is easy to cause indirect contact between the positive and negative poles of a certain button battery, which may cause electric leakage.
