Applications: Best for high-drain applications (eg power tools/Children's toys/Flash/Microphone/Measuring instruments).  Advantages: Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio — as little as 25% of the mass for the same power.The European Parliament has supported bans on cadmium-based batteries. Nickel–zinc is a good alternative for power tools and other applications. NiZn is a good battery choice for applications requiring high-power and high-voltage.Nickel–zinc cells have an open circuit voltage of 1.85 volts when fully charged and a nominal voltage of 1.65 V. This makes NiZn an excellent replacement for electronic products designed to use 1.5 V alkaline primary cells.NiZn batteries do not use mercury, lead, or cadmium, or metal hydrides, all of which can be difficult to recycle. Both nickel and zinc are commonly occurring elements in nature, and can be fully recycled.NiZn cells use no flammable active materials or organic electrolytes.Properly designed NiZn cells can have very high power density and low-temperature discharging performance, and also can be discharged to almost 100%, and recharged without problems.Zinc is a cheap and abundant metal, the 24th most abundant element in the Earth's crust, and is not dangerous to health. Common oxidation is +2, so charge and discharge move two electrons instead of one as in NiMH batteries.

PRODUCT FEATURES：All-in-one design for convenient operationsBluetooth connection make it more intelligent to record real-time data, and you can easily share them with your family and doctorRechargeable Li-ion battery with Type-C cableLarge LED screen make it easy and clear to readHelpful functions: 199 memories for one person, Irregular heartbeat detection, voice broadcastDevice Description This Blood Pressure Monitor is designed to measure systolic pressure, diastolic pressure and pulse rate of adult by a non-Invasive technique, with an inflatable cuff wrapped around the upper arm. The method to define systolic and diastolic pressure is similar to auscultatory method, though it uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alternations of cuff pressure into electrical signals. Based on analysis of these signals, the systolic and diastolic blood pressure is defined, and the pulse rate is calculated. This is an extensively used technique applied in blood pressure monitors, also known as “oscillometric method”. The main components of the Blood Pressure Monitor include main unit and cuff. For the outer housing of the main unit, it’s made of HI-121H material. The two types of cuffs have been clinically validated to be matched with the device, suitable for adults with arm circumference from 22cm~42cm. The cuff is consisted of fabric and an inflatable bladder inside. For critical electronic components, there is medical switch power supply, PCB, thermistor, pressure pump, motor, release valve and pressure sensor. The device also enjoys a function of detecting irregular pulse rate. When measurements were performed, the monitor will record all pulse intervals and calculate the average. If two or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±25% of the average; or if four or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±15% of the average, the irregular pulse symbol will be displayed along with measurement results. An embedded Bluetooth wireless connection module in the device allows it to connect with matching receiving ends. When a measurement is done, the results will be displayed on LCD, and the measured data will be transferred to the APP via Bluetooth. This Blood Pressure Monitor is a digital monitor intended for use in measuring blood pressure and pulse rate with arm circumference ranging from 22cm to 32cm (about 8¾˝-12½˝) or 22cm to 42cm (about 8¾˝-16½˝) . It is intended for adult indoor use only. Power Supply: 3.6V 1000mAH Built-in rechargeable li-polymer battery Measurement Items: Measuring systolic and diastolic blood pressure and pulse rate of intended population, including irregular pulse rhythm detection. Cuff Deflation Automatic deflation Blood Pressure Measurement: 0mmHg ~ 299mmHg, 5℃ - 40℃ within ±3mmHg (0.4kPa) Pulse Rate Measurement: 40-199 beat/minute, ±5%
