Hi!
1) By the way, batteries are really new (or "China new")? ;)
If they really new then maybe not start-formed. In this case after little time they will get steady (end of problem). If they are "China new" - it worse, their real capacity usually less then 75% from declared.
2) Try to check batteries connectors, wires and their eyelets. If there is weak contact - charging will be wrong (low current)...
3) Check small orange (voltage sence) connector...
4) Look, what happened with P-62, P-63, P-74 ang P-75 settings? maybe there something is wrong...
Maybe, it will be helpfull?
P.S. Please, excuse my weak english.

Some of the less expensive UPS devices have two sets of plugs. One set provides backup power and the other set only provides surge protection. You need to ensure that the devices for which you want backup power are plugged into the correct outlets on the UPS.

if this comes sometimes and goes, this means that the power to ups is sometimes deviating from the specific ups input range, hence the ups is rejecting it. mesure the input voltagesand frequency with a multimeter and check whether they match the specified ones in the ups manual. aslo with some ups there are switches that you use to set the input voltages or number of phases in the ups input. check the manual to see whetther your ups has such.
