Lithium Iron Disulfide (Li-FeS2) is a newcomer to the primary battery family and offers improved performance. It has a higher capacity and a lower internal resistance than Alkaline. This enables moderate to heavy loads and is ideal for digital cameras Where it can give up to 7 times the life of an Alkaline battery.

Further advantages are improved low temperature performance, superior leakage resistance and low self-discharge, allowing 10- 15 years of storage at ambient temperatures. Low weight and minimal toxicity are added benefits.
