Changing the Battery Backup Unit

The optional MegaRAC G2 Battery Backup Unit must be replacedevery 400 cycles. Cells retain 80% of their original capacity after 400cycles. A cycle is defined as a full charge (4.2V) followed by a fulldischarge (2.8V). Keep in mind that cycling or storing the cells atelevated temperatures can reduce the cell capacity and cycle life.Cells discharged and stored at low temperatures can extend the shelflife of the batteries.

Storage

If you keep a stock of extra MegaRAC G2 batteries, store them atroom temperature.

Note: The recoverable capacity of cells stored for over one year atroom temperature and fully charged is 94%. The retained capacity ofthese same cells is 87%. This means the self-discharge rate for a fullycharged cell is approximately 150 mAh per year or 427 uAh per day.The self-discharge rate for cells is non-linear. A partially charged cellhas a self-discharge rate of about 80 uAh per day.
