What does the mA marked on the rechargeable battery mean? Does the larger the number, the greater the power?

mA is a unit of current, not a unit of power. What is marked on the battery is mAh - that is, milliampere hours. For large-capacity batteries, it is marked ampere-hour (Ah). A battery is like a pool. The water flow rate of a pool can be multiplied by time to express its capacity to hold and discharge water. Batteries similarly use current hours to express charge and discharge capacity, which is convenient and intuitive. The larger the mAh number is, the larger the battery capacity will be and the more expensive it will be. In practice, such as in DC machines, the larger the battery capacity, the better. Batteries with excessive capacity are not only expensive, but also have a short life. Generally, 1600-2000mAh is enough. What does the mA value superscripted on the rechargeable battery mean?

To be precise, it is mAh, milliamp-hour.

Milliampere-hour (mAh) is a small unit of the main unit ampere-hour (Ah). .1Ah=1000mAh

The power of a general rechargeable battery is mAh,

It is defined as the current generated by complete discharge under a certain discharge time.

For example, 1300 mAh means that the battery is fully discharged within 1 hour and the current is 1300 mAh.

So the larger one means the greater the capacity. What does the 1000mAh mark on the battery of a mobile phone mean? Does the larger the battery have the greater the capacity?

Well, yes, that is the battery capacity. Assuming the working current is 10mA, it can work for 100h. What does the LR11326 marked on the rechargeable battery mean?

The relevant national standards stipulate the labeling of dry batteries. LR is an alkaline zinc dry battery. 11326 is a registered supplier information code. The product information can be found on the official website. Hope this helps you a little. What does the XXXX milliamp hour mark on the rechargeable battery represent?

It is a unit of electricity. For example: there is 750mAh on the mobile phone. This means that it can be discharged at a current of 0.75A for 1 hour.

It can also be calculated based on this and the voltage of the rechargeable battery. The amount of work the battery can do.
