Higher Ambient Temperature Tolerances and increase Serviceability



The LSIBBU08 can tolerate higher ambient temperatures around the battery backup unit as compared to the previous generation battery, with tolerances of up to 55C versus 45C for ambient cell temperature. There is also a remote mount option availabel which allows customers who have limited chassis space or a constrained thermal environment to reposition the battery backup unit away from the RAID controller card for cooling purposes.



A lower temperature environment will generally help prolong the service life of a battery backup unit, while high temperature and extreme conditions will shorten the battery life. For example, if the battery is set to a 12-hour DRT and 45C mode, it may not reguire replacement for the life of the RAID controller. However, using a 48-hour DDRT and 55C mode with your battery may cause a situation where the battery requires replacement after the first year of use.
