28.3.11 Glossary
LIB
Lithium Ion Battery, Li-Ion Battery
Self Discharge
The rate at which the battery charge level declines while it is just sitting in storage, usually quoted as a decline in
%-per-month.
Self-discharge increases with age, cycling and elevated temperature.
Discard a battery if the self-discharge reaches 30 percent in 24 hours.
Recoverable Capacity
The amount that a battery can be “fully charged back to” over time, usually quoted as a certain % of the full charge
level when the battery was initially manufactured.
