There are different types of lithium batteries.

Lithium Iron Disulphide batteries are a high output current
type.Used in high drain appliances such as toys, torches
etc.

Lithium Manganese are medium / intermittent drain types
(typ 20mA max continuous. from an AA cell). Used in
cameras etc.

Lithium Thionyl Chloride are low output types used to
support sram backup and the like (typ 1.5mA max cont
from an AA cell).

The really big plus with lithium batteries is their energy
density, their 10 year shelf life and -20degC operation.

The big downer is the price.
