Battery and Charge Circuit
Onboard Battery
The onboard battery is rated at 4.1 V with a capacity of 900 mAH. The
BDIMM 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 BDIMM. 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 between 0ºC to + 45ºC.
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/BDIMM contains the following text:
“Li-Ion Battery. Must be disposed of properly.”
Contact your local authorities to determine the appropriate method of
disposal.
