What precautions should be taken when using batteries in life?

We often use different types of batteries in our daily life and work, but there are also some aspects that require our attention when using batteries. Only by using batteries correctly can they play their best role and better protect ourselves and electrical appliances. Simply put, the following needs our attention:

(1) Do not mix old and new batteries, and do not mix batteries of the same model and type from different brands.

(2) Before use, check whether the contact points between the electrical appliance and the battery are clean. If necessary, wipe them clean with a damp cloth, and then install and use them in the correct manner after drying.

(3) Disassembling and heating the battery at will may cause damage to the battery, resulting in terrible consequences of burning and explosion.

(4) After using electrical appliances, contact with the battery should be cut off to avoid long periods of standby. The battery should be taken out and properly stored when not in use for a long time.

(5) Disposable batteries cannot be heated, charged or attempted to be recycled using other methods.

(6) AAA batteries and AA batteries cannot be mixed.
