자주 묻는 질문
10 질문A good way to remember '电池' (diàn chí) is to break it down. '电' (diàn) means electricity, and '池' (chí) can mean pond or pool, but in this context, it refers to a container. So, literally, it's an 'electricity container'. Visualize a container holding electricity.
You use '电池' just like you would 'battery' in English. For example, '我的手机电池没电了' (Wǒ de shǒujī diànchí méi diàn le) means 'My phone battery is dead.' Or, '这个玩具需要两节电池' (Zhège wánjù xūyào liǎng jié diànchí) means 'This toy needs two batteries.' Notice we use '节' (jié) as the measure word for batteries.
Yes, just like in English. You can specify the type by adding to '电池'. For instance, '锂电池' (lǐ diànchí) is a lithium battery, and '干电池' (gān diànchí) is a dry cell battery (like AA or AAA). '充电电池' (chōngdiàn diànchí) means rechargeable battery.
You can say '电池没电了' (diànchí méi diàn le). '没电' (méi diàn) literally means 'no electricity' or 'out of power'. It's a very common phrase.
The most common measure word for '电池' is '节' (jié). So, '一节电池' (yī jié diànchí) means 'one battery', and '两节电池' (liǎng jié diànchí) means 'two batteries'.
'电池' primarily refers to actual power cells. While '电' (diàn) can be used more broadly for electricity, '电池' specifically means a battery. You wouldn't use it to refer to, say, a car battery unless you were talking about the actual component.
That's a good question. '电池' (diànchí) is a battery, a device that stores chemical energy and converts it into electrical energy. '电源' (diànyuán) means 'power source' or 'power supply'. So, a battery is a type of '电源', but '电源' can also refer to a wall outlet or a power adapter.
You can ask: '这个需要电池吗？' (Zhège xūyào diànchí ma?) '需要' (xūyào) means 'to need', and '吗' (ma) is a question particle.
For 'the battery is low', you could say '电池快没电了' (diànchí kuài méi diàn le), which means 'the battery is almost out of power'. Or simply '电池电量低' (diànchí diànliàng dī) where '电量' (diànliàng) is power level and '低' (dī) is low.
That's correct! '电' (diàn) is a fourth tone (falling tone), and '池' (chí) is a second tone (rising tone). So, it's diànchí.
