Is it necessary to charge the UPS continuously ?

Question

Is it not enough to disconnect once it is charged. and then when the indicator shows the charge is low to charge it again ?

Answer 1

One should do that it is not necessary to charge UPS continuosly,but UPS usually discharge after some time i think thats why it is continously charged.

Answer 2

it is tickle charging that takes place when the ups is not in use and is required to keep the ups circuits functioning so that it works when your electricity bunks

Answer 3

Not necessary - but it is much easier to keep the charge on

Left to itself, the lead acid batteries will lose charge by progressive chemical reactions

So we charge it continuously at a slow rate (small current) called a "trickle charge"

If the UPS gets discharged like when power fails - then when the power is restored, the charging current automatically increases to bring up the charge quicker

Once it reaches a certain level of charge the current reduces and only a small "trickle" is maintained
