caveat:

　　The use of unauthorized Sealed 12v Battery in life safety products may cause product failure and increase the risk of injury, which you or your company is trying to protect. In addition, using battery manufacturers that are not approved by the original equipment may invalidate the product's warranty and increase the likelihood of litigation for you or your company.

　　note:

　　Do not charge or discharge the battery in a sealed case. The battery produces mixed gas inside. Under appropriate circumstances, such as extreme battery overcharging or short circuits, these gases may be discharged into the enclosure and may be ignited by sparks in the event of an explosion. Do not try to disassemble the battery. Contact with sulfuric acid may cause injury. If it happens, please wash the skin with plenty of water. Do not throw the battery into a fire; the battery so placed may rupture or explode. Disassembled batteries are hazardous waste and must be treated accordingly. Sealed lead batteries must be recycled or disposed of properly
