https://community.hpe.com/t5/disk-enclosures/raid-controller-battery-life-recharge-method/m-p/3919612#M22549 We have a POST message on a 5302 controller saying 'Array controller battery charge low'. I understand this means the battery is below 90 percent charge. Documentation states that if it does not charge up within 36 hours replace it.<BR /><BR />Should I follow this advice?<BR /><BR />Should I replace in any case?<BR /><BR />How does the battery recharge work? Is the battery charge constantly monitored by controller? Does it only charge when it 'sees' a problem during the post check? The only drain we put on the battery is during a reboot - which may sometimes require a full power off. So its literally seconds. Should this cause a drain of some 10 percent?<BR /><BR />Help please.... <BR /><BR />Thanks<BR />IanB<BR /> Tue, 02 Jan 2007 05:33:03 GMT Ian Belton 2007-01-02T05:33:03Z https://community.hpe.com/t5/disk-enclosures/raid-controller-battery-life-recharge-method/m-p/3919612#M22549 We have a POST message on a 5302 controller saying 'Array controller battery charge low'.
