1. Ambient temperature: The ideal working and storage temperature range of lithium-ion batteries is usually between 15°C and 25°C. Temperatures that are too high or too low will affect the performance and life of the battery. Avoid using or charging at extreme temperatures.

2. Avoid deep discharge: Do not fully discharge the battery to zero power, as excessive discharge may cause irreversible loss of battery capacity. When the device displays a message indicating low battery, it should be charged in time.

2. After a full charge, a short usage time may cause damage or failure of the battery. Run time varies depending on configuration and operation. For example, more frequent NIBP measurements will result in shorter run time.

4. Regular maintenance and inspection: For removable battery packs, you should check the appearance of the battery regularly to see if there are any damage, cracks, bulges, or loose poles. Keep the battery and contacts clean from dust and metal shavings.

It has excellent compatibility and is compatible with Philip equipment TC20 TC30 TC50 and other monitoring equipment. It also contains high-quality batteries and intelligent control chips, can be charged and discharged repeatedly, charges quickly, and has a long battery life.   Lithium-ion battery maintenance mainly includes the following aspects:   1. Ambient temperature: The ideal working and storage temperature range of lithium-ion batteries is usually between 15°C and 25°C. Temperatures that are too high or too low will affect the performance and life of the battery. Avoid using or charging at extreme temperatures. 2. Avoid deep discharge: Do not fully discharge the battery to zero power, as excessive discharge may cause irreversible loss of battery capacity. When the device displays a message indicating low battery, it should be charged in time. 3. Long-term storage: If you do not need to use the battery for a long time, it is recommended that you keep the power at about 40% to 50% and store it in a dry and cool place. Charge it regularly to prevent the battery from self-discharging and losing power. 4. Regular maintenance and inspection: For removable battery packs, you should check the appearance of the battery regularly to see if there are any damage, cracks, bulges, or loose poles. Keep the battery and contacts clean from dust and metal shavings. Following the above advice will help keep your lithium-ion battery healthy and extend its lifespan.   ► Specifications   Model U80221-4 Brand Philip Product Name Rechargeable Battery Voltage 11.1V Product Category ECG Delivery Method DHL ,Fedex ,UPS Payment Method Paypal,T/T,Western Union Warranty 90 Days Delivery 3-5 Working Days Technology Lithium-Ion Capacitance 7.8Ah MOQ 1 Piece Inventory In stock Packing Carton Power supply sourrce Electric Condition New Original     ►To charge the battery, follow these steps:   1.
