I have just replaced the battery in my APC ES 700 (same battery from new in 2009!) as it was showing only 9 minutes of battery time.
After charging the new battery for 24 hours, I connected my PC and Powerchute shows 9 minutes of battery time!
I tried connecting my PC to another ES 700 and Powerchute shows 40 minutes of battery time.
Is this a bad battery or have I missed a step in installing the new battery?
Thanks in advance for any suggestions
