I got this second hand APC smart-UPS 620 (VA) and well I was told a new battery had been put in it so yea I suppose it was worth 30 € just for the 12 V 14 A battery,
however it has been putting on the battery warning light, up to now it has been quite quite (unless the mains is accidentally knocked off and it cuts in can hear the transformer hum) just now though running on the mains it has suddenly started to hum like the transformer is working, does this mean the battery has finally started to charge up ? assuming it is a new battery it will need charging won't it ? the status lights are normal at the moment,
will the battery charge if it is just left plugged in but not turned on ? there is a relay click when I turn the main on and off even if the ups is switched off
