MUST's 19 inches rack standard backup battery is based on Lithium iron phosphate battery, It has been designed to provide backup power for telecom equipment or energy storage system in household. It has excellent safety, high energy density, long lifetime, very nice temperature performance, green power newly of excellent safety and high reliability.
Lithium Iron Phosphate can be used in most applications that use Lead Acid, GEL or AGM type batteries.
Suitable applications include:
•Switching applications and more
•Base transceiver station
•Electronic cash registers
•Microprocessor based office machine
High cycle life
4000 cycles @80% DoD for effectively lower total of ownership cost
Longer service life
Low maintenance batteries with stable chemistry.
Built in circuit protection
Battery Management System (BMS) is incorporated against abuse.
up to 6 months thanks to its extremely low self discharge (LSD) rate and no risk of sulphation.
Save time and increase productivity with less down time thanks to superior charge/discharge efficiency.
Extreme heat tolerance
Suitable for use in a wider range of applications where ambient temperature is unusually high: up to +60°C.
Lithium batteries provide more Wh/Kg while also being up to 1/3 the weight of its SLA equivalent.
•Do NOT short circuit, reverse polarity, crush or disassemble.
•Do NOT heat or incinerate.
•Do NOT immerse in any liquid.
•Store at 30~50% SOC. Recharging every 3 months is recommended. The storage area should be clean, cool, dry and ventilated.
