I want to share a tip that I have maintained for more than 10 years now, which is about battery usage.

At first, I started using these "rechargeable" batteries because of the nature of my work. The student-era job that the Creator assigned to me involved audio recording, and the equipment at that time still had to use "carbon-zinc" batteries (also called "rabbit" batteries).

With many continuous hours of work, the number of "rabbit" batteries required would be very large and the cost would be very high, so I decided to switch to using 12 "rechargeable" batteries to keep my devices charged continuously.

Looking back now: these batteries, after "retiring" when the work ended, continued to be used in my daily life. At first for electronic toys and household clock devices, and later for remote controls, air conditioners, etc.

To date, these batteries have been used for nearly 10 years and are still in very good condition, with negligible "capacity loss". (The remaining ones are missing because I lost them — friends "borrowed and didn't return").

The photo on the left is the number of batteries collected in 2 weeks.

You can use one large, dry plastic bottle — put all the batteries inside, close the lid when it is full — and send it to private companies / licensed collection organizations during the environmental action month in major cities in Vietnam.

Please keep these battery containers in a well-ventilated place! (Because before they are sent for processing, if the weather is too hot they may cause fire or explosion).
