JMS SP-500 8.4V 2000mAh 7N-1200SCK Compatible Battery
► Brief Introduction
This battery is a medical compatible battery produced by a third party. It can replace the original medical battery model 7N-1200SCK and provide a portable, stable and reliable power supply for medical equipment. It can be adapted to the JMS SP-500 series monitors to solve the risk of power outages during the patient transfer process or bedside monitoring room, ensure the uninterrupted use of the monitor modules (ECG, blood oxygen, blood pressure, etc.), continuously detect the patient's vital signs, and ensure that the doctor understands the patient's physical condition.
This battery uses NI-MH, with a small size of about 90.00 x 43x 42 mm, a light weight of about 479g, a voltage of 8.4V, and a capacity of 2000mAh. It can support the JMS SP-500 series monitor to cycle charge and discharge for more than 600 times (more than 80% discharge rate, which will vary depending on the use environment), and is durable.
