What are the advantages and disadvantages of rechargeable batteries?

The advantage of rechargeable batteries is that they have a long service life. Even though they are more expensive than primary batteries, they are very economical from the point of view of long-term use, and the load capacity of rechargeable batteries is higher than that of most primary batteries. However, the discharge voltage of ordinary secondary batteries is basically constant, and it is difficult to predict when the discharge will end, so it will cause some inconvenience during use. However, the lithium ion battery can provide the camera equipment with a longer use time, high load capacity, high energy density, and the drop of the discharge voltage will weaken with the depth of the discharge. Ordinary secondary batteries have a high self-discharge rate, so they are suitable for high-current discharge applications such as digital cameras, toys, power tools, emergency lights, etc., and are not suitable for small current discharge occasions such as remote controls, music doorbells, etc. Places that are not suitable for long-term intermittent use, such as flashlights. At present, the ideal battery is a lithium battery, which has almost all the advantages of the battery, and the self-discharge rate is extremely low. The only disadvantage is that the charging and discharging requirements are very strict, which is a guarantee of life.
