Battery doesn't charge to full - APC Smart-UPS 1000XLI (SUA1000XLI) UPS System

If your Charger is OK, then the problem is your units' battery was drained. Change your units' battery.

Take your batteries out, and take them down to .a battery shop. Have the battery load tested, Reading the voltage under no load conditions will not tell you much, normally the batteries voltage gives you its state of charge. These batteries will show a full charge at no load, as soon as you put any load at all on the voltage drops off and you don't have much in amperage output. The amperage is what is important when you right down to it. When load testing your battery they will use an instrument that they punch in the cranking amps. The instrument will look for the voltage drop off at a load of what ever amp value you punched into the instrument. The instrument will give you a pass\fail indication for the cranking amps value the technician punched into the keypad. There can be a problem when load testing batteries. The technician doesn't key in a amperage value, This is what happened to me. The instrument when no value is entered will use a default value, Say the default amperage is usually set at around 200 Cranking amps. My technician was either rushed or just being lazy. He set the load tester to use the default values, my battery passed with the tester set up the way it was. My battery is a 35 amp\hr battery and puts out 480 cranking amps In actuality my batteries weren't putting out nearly that much. It would put out 265 cranking amps for about 2 seconds then die. He told me the batteries were good. When i brought the batteries back to him
i didn't let him take them into thee back room. THIS TIME HE DID THE CHECKS OUT IN PLAIN SIGHT OF ME. I asked to do a comparison between my batteries and new ones. We had to retest a number of time in order to find the upper limit of the new batteries. As it turned out my batteries were bad and all my problems disappeared with my old batteries. NOTE, scooters use deep cycle batteries only Glass mate batteries if you want to take your scooter on a flight.

Now if you had your batteries load tested and you know their good, its got to be the charger thats malfunctioning. Check the charger connection points make sure there tight. One connector should go to the negative battery terminal, the other connector should go too the positive terminal and read +24v. Make sure the connections are solid.

How long does it take to charge a battery? There are allot of variables to this but generally speaking if a charger is a four amp charger and you got a 35amp/hr battery it will take roughly 8 hrs to charge. Batteries typically don't like to be cold. My batteries are 35amp/hr my scooter will go 25 miles @ a max speed of 6 mph. The run time is roughly 5.5 hrs with a draw of about 6amps

no it doesn;'t need to be turned on to charge it, it should usually take about 8 hours to get a full charge

Are you sure the battery is good, just because you charged it doesn't mean it is any good and reached full voltage. I also suggest you disconnect the battery negative cable for 5 minutes to reset the system.

It is possible that the battery is already full charge or nearly full and the chrger senses this and doesn go into charge mode.

Using a battery/volt meter, check if the battery has a full charge. Also check if there is an on/off switch on the back of the solar panel. If the batteries are removable and are standard batteries, charge them using an AC battery charger the first time. If not, you may have a defective solar panel and should return it to the store/manufacturer.

Hi.
Since this is using Ni-Cad battery system, I would charge it between 12 - 16 hours to ensure a full charge has been accomplished.

The original owners manual may say quite alot less, but Ni-Cad batteries are notorious for taking a long time to fully charge.

Too bad it doesn't have a li-ion battery...those only take about 4-6 hours for a full charge, and thats only if they are totally dead!

I hope this helps you out.
Good luck to you, and have a good day!

HI Cws666, try to charge your computer for a full 3 - 5 hours without interruptingit, than try again.
If that doesn't work, try buying a new battery.
If that doesn't work send it to computer's brand labs.
