Question about APC BE500U ES 500 USB BACK-UPS 500VA/300W 120V (NEWITEM13161417) UPS System
I have this weird problem since many years. My UPS does not charge my new battery even if it is online. I have a Back-UPS ES 500 model from APC. Until few months ago I thought the batteries life is gone and mistakenly replaced the batteries in good condition with a brand new Exide battery. But still after this, it is still in that pathetic condition. It does not charge the batteries enough and sometimes doesnot charge at all even if it is left online for almost a complete week!. Need experts help what could be the problem with UPS. It is really irritating. Thanks in advance for your suggestions/help.
i think by replacing the battery has not been the solution to the problem
u need to check the battery charging voltage when turned ON with main electricity, if no voltage present from charger, there is no question of battery getting charged and also once the battery is down with charge it may not re charge hence the indicator and alarm.
recomended to nearest service centre

yeppers...those APC units sometimes kick the monitoring software. sometimes you need to unhook the connection cables(like a reset) so that the firmware can 'unlock' which can cause that christmas tree effect on the panel lights.

On this unit, the likely culprit is the battery and that it needs to be replaced.
With that, you may want to think about the pros and cons of replacement versus buying an entirely new unit.
This unit is a relatively low end ups and the surge supression uses MOVs that wear out with repeated absorption of energetic spikes. That's why the better (and higher cost) UPSs and surge suppressors don't use them. They're not really that good anyway due to their relatively high transient impedance. The better equipment uses a "transorb" -- basically a back-to-back high voltage zener diode optimized for low breakover impedance and high instantaneous power capability. Unless the transient exceeds the design parameters of the circuit, these do not wear out and do not degrade. That being said, I will assume that you would likely replace this unit with a similar one.
The flashing may not be the battery at all and may be the charging circuitry, thus your new battery may not live very long (half the life that you would expect.
Many batteries out there are refurbs and have issues as all used parts do.
If you contact APC, they will likely give you a 35% discount on purchasing a new product.
The difference in price in the battery replacement vs. ups replacement at this level may only be a few dollars more.
I promise that I am not a UPS salesman, I just deal with many on a daily basis; therefore I am giving my two cents to try to thelp you avoid problems a year from now.

Testimonial: "Outstanding answer with right amount of detail. I swapped battery with identical APC UPS that I have and vfd that battery was cause of warning tone."
It sounds like you need a new battery. If the APC is more than 3 years old, that is likely the problem. You can get a new battery from http://www.batteryinternational.com/apc-backups-es-be500u-ups-battery-ups-batteries-f2.html

Tips for a great answer:
I have the same problem with an apc smart-ups VS 650.
New batteries - charge in batteries is good (also tested under load).
When AC power fails, no power is supplied to PC connectors by the UPS.
UPS self test works fine. UPS does not report any problems via software - Power Management under Windows XP.
