What other types of batteries can the Tianqiu 521 coin cell battery be replaced?

This is necessary to be replaced, because the battery of the same model can match the battery slot of the watch.

Button cell, also known as button battery, refers to a battery with an external size like a small button, generally with a larger diameter and thinner thickness (compared to cylindrical batteries such as No. 5 AA batteries on the market).Button batteries are divided into batteries from the appearance, and the corresponding batteries are classified as columnar batteries, prismatic batteries, and special-shaped batteries.

Hello:——1,The model of the button battery is closely related to the external dimensions, and the shape of different types of button batteries is different. When replacing the battery of the electronic watch, the shape of the battery must be the same, that is, the model must be the same.

Coin cell batteries of the same model, there is a difference in its material. For example, zinc oxide button batteries, silver oxide button batteries, etc. Different materials have great differences in performance.

For example, silver oxide button batteries are much more durable than zinc oxide button batteries.

The watch battery is generally a silver-zinc battery, as long as the size and voltage are consistent, you don't have to worry about the model. The number of products from different manufacturers may be inconsistent, and using the same model is an insurance method.

As long as the voltage is right, it can fit in.

The model must be the same, otherwise you either won't fit in or won't be able to reach it.

Hello, unless the electronic specifications are the same, it cannot be replaced, and it is easy to damage the device.

A13 can only be used instead of A13, and the volume voltage of other batteries cannot be universal.

The string resistor is not allowed because it affects the current. The 2032 button battery is 3V, and the 18650 lithium battery is, and the voltage that can be obtained by connecting a diode in series can replace the 2032 button battery, and the effect is good.

It is recommended to buy it from the Internet, because with a different type of battery, the voltage or volume may not be suitable, and it is not worth it if the watch is damaged.

I'm also looking for the LR750 and can't find it anywhere.

It's completely possible, as long as the voltage is consistent, but you must pay attention not to leak when using No. 5 batteries, in fact, CR2032 is easy to buy, cheap 2 yuan a piece, the most important thing is to use this type of battery where the power consumption is very low, there is no need to use No. 5 batteries.

It can be replaced, and I will replace the battery of my digital perpetual calendar without any problems. Replace the battery that buys a good one, and the poor battery is not as durable as the button battery!

The same v won't burn out.

From an electrical point of view, as long as it is a 3V battery, it can be replaced.

However, all products with button batteries are usually very small in size, and the designed button battery clips have strict dimensions, and different models of button batteries are either different in diameter or different in thickness, so you have to take this problem seriously.

No, because the size is not the same. For example, 2032 and 2025 are all different in size, so they can't be used at all. 20 diameters 32 and 25 are heights.

Yes, it's just different in diameter or thickness.

Watches are generally used more AG4, with the same diameter and different thickness.
