Installing or removing the ThinkServer RAID 700 Battery

This topic provides instructions on how to install or remove the ThinkServer RAID 700 Battery (also known as the ThinkServer 9260-8i Battery and hereinafter referred to as the TR 700 Battery).

The TR 700 Battery protects the integrity of the cached data on the ThinkServer RAID 700 Adapter by providing backup power up to 72 hours in the case of a complete ac power failure or a brief power outage. It has built-in functionality to automatically charge the battery pack and to communicate battery status information (such as voltage, temperature, and current) to your server. It also provides an inexpensive alternative to using an uninterruptible power supply, and a second level of fault tolerance when used in conjunction with an uninterruptible power supply.

The temperature of the TR 700 Battery is generally 15-20°C (59-68°F) higher than the ambient temperature during fast charge. Therefore, to complete a recharge cycle, the ambient temperature should be lower than 55°C (131°F). If the ambient temperature exceeds 55°C (131°F), the recharge cycle will terminate prematurely, thus preventing the TR 700 Battery from reaching a fully charged state. A recharge cycle lasts at least six hours under normal operating conditions.

Attention: It is recommended that you replace the TR 700 Battery annually or after 500 recharging cycles, whichever comes first.
