Hi, I predominantly use two types of VRLA AGM batteries with the following characteristics @ 25°C

a) Ritar DC12-200 (AGM 12V 200Ah@20hr-rate)
Cycle Use Voltage: 14.6V ~ 14.8V (-3mV/°C/Cell), max current: 60A
Float Charging Voltage: 13.6V ~ 13.8V  (-4mV/°C/Cell)

b) Gaston GT12-200AG (AGM+GEL 12V 200Ah/C20)
Cycle Use Voltage: 14.4V ~ 15.0V (-30mV/°C), max current: 50A
Float Charging Voltage: 13.6V ~ 13.8V (-20mV/°C)

I have the following settings on 24VDC and 48VDC Axpert MKS inverters with 2*200Ah and 4*200Ah batteries in series:

02 - Maximum charging current: 20
05 - Battery type: USE
11 - Maximum utility charging current: 20
26 - Bulk charging voltage (C.V voltage): 29.2 & 58.4 on 24VDC and 48VDC models respectively. NB: Maximum on MKS inverters
27 - Floating charging voltage: 27.4 & 54.8 on 24VDC and 48 VDC models respectively
29 - Low DC cut-off voltage: 21 & 42 on 24VDC and 48 VDC models respectively
32 - Bulk charging time: AUt (5K model only)
33 - Battery equalization: Ed5 (disabled)

In my part of the world, the high/low temperature typically varies from 22/13°C to 27/16°C and is rarely below 10°C or above 30°C over the course of the year. 

In your opinion, are these battery settings optimal for power backup applications?
 

As basic as this may sound, are "cyclic use" and "standby use" markings on batteries synonymous with absorb (bulk?) and float voltages?

Yes. I wish they talked the same language.
