We have a Best 5.3 KVA system that was in the office complex we leased and the batteries died. It appears to have been installed years ago and not maintained. The spill proof batteries where dry when we pulled them out. Not knowing if the inverter error message was for real or because of the old batteries we did not want to pay $600 for a new set so I picked up 4 new deep cycle batteries at Wal-Mart. Since they are not sealed like the others we just left the front off of the case and assembled the 48 volt pack in front of the unit and made the connection. In just a few hours it brought the 4 new batteries to full charge and seems to be working fine.
My question has to do with battery charging principles. While I found one thread on this subject it was more of opinions than facts or links to other sources. If I build a second 48 volt pack and connect it in parallel, how will that effect the charger? Does a battery charger try to exceed its ability because of the change in load or just work normally but for twice as long to bring the batteries back to a full charge in the event of a power outage or both or some other answer?
I know the UPS output is fixed and my only desire to see if I can more or less double my run time without destroying the charger in the Best Unit. Over the past year we have just had the lights to blink a few times but if you are out in the utility room where the Best is hard wired into our electric system you can here it change over from time to time but not detect the loss of power visually. After hours we plan to only have 3 servers drawing a max of 500 watts. Thanks with your help on this charging question.
