What does the voltage and ampere of a battery mean?
1 Answers
Here is the meaning of battery voltage and ampere: Battery ampere (A): Ampere is the unit of electric current, abbreviated as A, where 1A equals 1000mA. Battery ampere refers to the battery capacity, measured in milliamperes (mA) or amperes (A). For example, a mobile phone lithium battery might be 2500mAh, an 18650 lithium battery 1200mAh, while automotive lead-acid batteries are usually denoted in amperes, such as 120A or 200A. Battery voltage (V): Called volt, it is the unit of voltage, with the English symbol V. V~ denotes alternating current (AC), while V— denotes direct current (DC). Examples include household AC at 220V and DC sources like 1.5V batteries or 12V car batteries. 1V equals 1000mV, with mV commonly used in electronic circuits.
