New battery; 97% charge

[BillP]

I've just bought and installed a new battery for my BR 1500 UPS.

Mac OS 10.4.10

PowerChute Personal 1.3.4

Although I've had the battery on charge since buying it, and experienced no problems whatsoever with the UPS, USB connection, System Prefs or indeed the power, the percentage of charge showing in the menu bar varies from between 97% and 100%.

Is that normal, OK?

Since carrying out your suggestions earlier, today (thanks again!), it's crept up to 100% and stayed there.

Yes a genuine APC replacement battery.

I'd suggest doing a calibration on the unit. To do the calibration, plug in a 30-40% load and allow the unit to run on battery until it reaches a low battery condition (continuous beeps that are about a second apart). The load can be a couple of lamps and a computer monitor, or whatever you can come up with. Just don't have your computer as the load. Then, just let the unit charge back up and see what you have for readings. You may also want to just reinstall the software afterward if you don't see any improvement.

Thanks!

I ran it on peripherals only for about an hour. But not down to 'Battery Low'.

Is that important?

Nothing odd... LED showed as being 'On Battery' intermittent four-beep every so often.

No continuous tone. No flashing.

When I re-attached to A/C outlet and then plugged in my G5 computer and powered up, battery level at 84%.

Since I've been writing this message, it's risen to 86%.

Any other ideas?

Is it normal for a new battery to show only 97% etc charge with full load?
