II. WHAT SHOULD PAY ATTENTION TO OF USING SUCH BATTERY?


The use of 12v DC rechargeable battery/batterie must comply with the following provisions: 

  • 1.    Avoid battery short circuit.

  •       Because a short circuit will cause internal a high current and then result in electrolyte leakage. if battery tabs are connected to conductive object, it is easy to cause battery short circuit. Battery external short circuit can also cause heating and damage of batteries. An appropriate protection circuit can be used to protect the battery during the accident.


  • 2.     Environment Temperature.

  •         This 12v batteries should be stored at room temperature, and make sure 50% to 30% electricity at least if you want store it for a long time. and also, if it is allowed, batteries should be charged once every six months to prevent battery from over discharge.


  • 3.     Re-assembly Notice:

  •         if you need to re-assemble the battery into higher capaity, you should pay attention to all conductive material / substances contacting the polarities, because of potential contact with the conductive element is easy to cause the plastic film get overheat and cause corrosion of aluminum layer, and the leakage of flatulence.
