Tripp Lite SmartPro SMX500 UPS - faulty?
Hi
just got this UPS out of my storage and replaced the batteries. When it is powered up it shows three green lights indicating it is on, load is okay, and fully charged. Powering it off with the button it shows one green light showing the battery is charged. When I disconnect the power cable two amber lights come on. Is this indicating a fault? Or is it supposed to do that? Won't the lights eventually run the battery down and ruin them?
The problem is I want to use this UPS in a portable rack that will only be connected to the mains when in use every few weeks. Powering those two LEDs with about 0.06W will run a 7aH battery flat in 1400 hours. Can they be made to go out? The manual says
Before storing your UPS, turn it completely OFF: With the UPS ON and receiving utility power, press and hold the “ON/OFF/STANDBY” button for one second (an alarm will beep once briefly after the interval has passed), then unplug the UPS from the wall outlet. If you store your UPS for an extended period of time, recharge the UPS batteries once every three months: plug the UPS into a wall outlet, allow it to charge for 12 hours, and then unplug it and place it back in storage. Note: after you plug the UPS in, it will automatically begin charging its batteries. However, it will not supply power to its outlets (see Quick Installation section). If you leave your UPS batteries discharged for an extended period of time, they will suffer a permanent loss of capacity."
it doesn't say anything about the lights. three months is about 2000 hours so the batteries will be completely discharged.
thanks
