.Meet the relevant national standards and requirements for batteries .All finished battery products are calibrated and tested before delivery. They can be used directly and normally.This is a lithium battery used in medical equipment. Consumer electronics and many other industries are increasingly paying attention to product mobility, and medical device manufacturers are no exception. This trend has improved the performance of on-site rescue equipment, monitoring equipment, and fixed medical equipment, thereby driving the health care industry. developing. However, in addition to portability, medical device manufacturers certainly hope to produce highly reliable devices, because people's lives are often hanging by a thread. A broken cell phone is an annoying thing, but if the portable heart monitor or infusion fountain stops functioning when the battery runs out, the end user - and the patient - will face much more serious problems. Therefore, the requirements for medical equipment batteries will be much higher, and higher requirements are put forward for battery stability, battery life, and portability. This is a new opportunity and a new challenge for the battery industry.Do not mix fresh batteries with used batteries. Do not mix batteries with metal stuff together. Do not insert batteries with the (+) and (-) reversed. Do not use Efest batteries with defective E-cig mods. Do not disassemble, dispose in fire, heat or short circuit. Do not put the battery in a charger or equipment with wrong terminals connected.
