Lithium-ion desk lamp batteries fail within a week
As for the current size of desk lamp lithium batteries, it is generally recommended to choose between 0.5A and 2A. The current in this range can not only garreduce the charging speed, but also extend the life of the lithium battery.
Specifically, if the current is too low, the charging time will be relatively long and this may cause crystallization inside the battery, affecting its lifespan. And if the current is too large, although the charging speed will be faster, it will also cause certain damage to the battery and shorten its life.

Actually, it's very simple. The battery is not working. The batteries they bring are not very good. The best are nickel-cadmium batteries with very low energy density and a pitiful capacity of only one. a few hundred mAh. The key is that many of them may use old batteries, so the battery voltage will drop quickly when used, so you won't be able to use it for long.
Actually, there is a very simple way to solve this problem.
