What to pay attention to when using alkaline batteries

When using alkaline batteries, pay attention to the following points:
Leaking electrolyte
Alkaline batteries that have been left for a long time will leak the electrolyte. Since the electrolyte is a corrosive alkaline substance, potassium hydroxide, it will irritate the eyes, the respiratory tract and the skin; the electrolyte will also attack metals and damage electronic parts, so The electrolyte leaked from the battery will also damage the products using the battery, especially the electronic products.
Do not charge alkaline batteries
Charging alkaline batteries can also cause the battery to leak electrolyte, or even rupture the battery. A very small number of alkaline batteries are designed to be charged, but they can only be charged with a relatively small current. To achieve a significant charging effect, it usually takes a whole day or more, and the number of recharges is not large, which is quite inconvenient. So it is already difficult to find in the market. Some chargers claim that they can charge ordinary ordinary disposable alkaline batteries, but such products do not guarantee the performance of the charged batteries.
Use the same type of battery
When using more than one battery, use the same type or even the same brand of batteries; avoid using new and old batteries together. Doing so increases the risk of leakage of the electrolyte.
Store separately when not in use
When the battery-using device is not used, the battery should be taken out and stored separately to avoid damaging the battery-using device when the battery is stored for too long and the electrolyte leaks out.
