What Do Standby and Cyclic Use Ratings Mean for Batteries?

AI Thread Summary
Standby and cyclic use ratings for batteries indicate their optimal voltage and current for different applications. Standby use typically involves lower voltage (12.6-13.8V) and a lower initial current (0.75A), suited for applications requiring a constant power supply over long periods. In contrast, cyclic use requires higher voltage (14.5-14.9V) and a higher initial current (1.5A), designed for applications with frequent discharges and recharges. These ratings directly relate to how the battery should be charged and maintained for optimal performance. Understanding these specifications is crucial for ensuring the battery's longevity and efficiency in specific use cases.

I've been doing a project recently that requires a UB1250ZH Universal Battery rated 12V and 5Ah. Although I understand the concept of Ah, I'm having a difficult time in figuring out what the ratings for standby and cyclic use mean. For an example, it says -

Standby Use: 12.6-13.8V, the Initial Current is 0.75A
Cyclic Use: 14.5-14.9V, Initial Current: 1.5A

Does this have something to do with recharging?

Thank you! Any help would be much appreciated.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
