search for: 9ah

I have taken out the batteries and measured them with a multimeter. They put out 13V (they are rated 12V 9Ah). Putting them back again and disconnecting the UPS from the mains it is kept on, powering all the connected devices. The shutdowns only occur when the UPS is being monitored. Are you sure it's a battery problem? Do UPS perform further tests when they are being polled for data? I'll chec...

...meters. The NUT 'upsstats' battery voltage meter for these E5115 UPS boxes is almost in the lower level RED zone which is just under 40 volts. The GREEN zone seems to be 48 to 55 volts with a RED zone above that. Here's the confusing part: These Eaton E5115 UPS boxes only have 3x 12v 9Ah sealed lead-acid AGM battery blocks inside them. I verified that after I recently changed out some aged batteries from those boxes. There is no room for any more battery blocks in the case. NUT 'upsstats' reports the battery voltage as 40.25 volts for 1 of the UPS boxes and 39.02 volts for...

What sort of load did you have in parallel with the multimeter? (This is why Wolfy mentioned the light bulb: if the battery has developed excessive internal resistance, it will show proper voltages when tested open-circuit, but will read lower with a load.) > Putting them back again and disc...

...pecified at 9 Ah. With end-of-test at 10.5V, which you'll find on the spec sheet. Of course, the actual time will not be 20h, and one could attempt to find the rate which leads to 20h, but I don't think that's a sensible thing to do. Basically, if I get > 8.5Ah when discharging a 9Ah at 450 mA, I call it good. And > 8 Ah I call it ok, sort of they are making an 8 Ah battery and the marketing people call it 9. I will probably be getting some new batteries over the next few months and will test them on intake, and weigh them too. Thanks for posting about your journey; it...

...y has two very important electrical characteristics for your UPS: nominal voltage (V) and capacity (Ah). Usually you will meet 6V (3 cell) and 12 V (6 cell) batteries in UPS. This represents nominal voltage of battery. In 70% of ups devices usually is used battery of 12V/7Ah in some rare cases 12V/9Ah or 6V/4.5Ah. Depending on ups power rating in output different number of batteries is used and common values are: UPS Technology UPS rated power number of batteries total battery voltage Interactive 600VA...
