1, can charge differently: rechargeable battery can be charged, ordinary battery can not be charged.
2. The internal resistance of the battery is different: the internal resistance of the rechargeable battery is small, and the internal resistance of the ordinary battery is large, so the ordinary battery is not suitable for a large current discharge device such as a digital camera.
3, the amount of self-discharge is different: the self-discharge of the rechargeable battery is relatively large, the self-discharge of the ordinary battery is relatively small, so the rechargeable battery is fully charged, and there is no need to easily leak light (about half of the two months will leak light).
4, different storage resistance: rechargeable battery is not resistant to storage, ordinary battery is resistant to storage, long-term use of rechargeable battery performance will be greatly reduced, to the extent that it can not be used.
5, the battery terminal voltage is different: the terminal voltage of the rechargeable battery is 1.2V, the terminal voltage of the ordinary battery is 1.5V, but because the internal resistance of the rechargeable battery is small, the voltage is reduced during use, so in most cases, two Generally available.
