BBM Functional Description

Status Indication

Battery status can be checked, and the battery can be reconditioned, or charged using the Intelligent Battery Backup Unit dialog box in Global Array manager Client. This is accessed by selecting the Intelligent BBU option on the Administration menu. Please refer to the Global Array Manager Client Software Installation Guide and User Manual.

Battery and Charge CircuitOn-board Battery

The on-board battery is rated at 4.1 V with a capacity of 900 mAH. The BBM has a DC-DC converter that converts 4.1 V to 3.3 V, which is the nominal voltage required for the cache.

Battery Charger

Battery charging is automatically handled by the BBM. No manual preconditioning needs to be performed by the user. If the battery capacity falls below a predetermined level (which is likely to happen after a power failure), the battery charger goes into a quick charge mode. The battery charger will operate in a temperature range from 0°C to +45°C.

Disposition of Failed Batteries

Currently, requirements for disposal or recycling of rechargeable Lithium- Ion batteries are under consideration by many agencies, both local and international. Lithium-Ion batteries should not be punctured or incinerated (the electrolyte can generate steam and cause the gas to explode).

The battery on the BBM contains the following text:

“Li-Ion Battery. Must be disposed of properly.”

Contact your local authorities to determine the appropriate method of disposal.
