FAQ of 36V 5Ah UPS Lithium Battery:
1. What kind of UPS is the EG-3605A battery compatible with?
The 36V 5Ah UPS lithium battery is designed for built-in 1U rack-mount UPS systems, particularly those with high-rate discharge requirements (≤2KVA). Please confirm your UPS model supports external 36V battery packs and high-current discharge (up to 60A) before installation.
2. What cells are used in this battery?
This 36V 5Ah Lithium battery uses all new brand LiFePO4 cells, known for their excellent safety, thermal stability, and long cycle life. The internal configuration is 12S2P, providing a nominal voltage of 38.4V and 5Ah capacity.
3. How long can the 12C high-rate discharge 36V5Ah UPS Lithium battery provide backup power?
Typical backup time ranges from 5 to 15 minutes, depending on the load level and UPS efficiency. This UPS Lithium battery is ideal for short-duration emergency backup to allow safe shutdown or switching to generator power.
4. Is the 12C discharge real? What does it mean?
Yes, the 12C discharge rate is real and refers to its ability to discharge at up to 60A continuously (12 times its nominal 5Ah capacity). This makes the 36V 5Ah UPS Lithium battery suitable for high-current UPS applications that require fast energy output.
5. How long will this battery last?
Under proper conditions, the 36V 5Ah UPS Lithium battery offers a calendar life of over 10 years and a cycle life 4–5 times longer than typical lead-acid batteries. Actual lifespan depends on usage conditions, such as charge/discharge rate and operating temperature.
6. Can this 36V 5Ah UPS Lithium battery communicate with the UPS or monitoring system?
Yes. It is equipped with RS232 and RS485 communication interfaces for real-time monitoring, integration with intelligent UPS units, or centralized battery management systems.
7. Can I use this battery in parallel or series for larger capacity or voltage?
This 12C 36V 5Ah UPS Lithium battery is designed as a single-unit, standalone UPS battery pack. For parallel or series configurations, please consult with our battery engineer, as multiple packs require BMS coordination to ensure safety and balance.
