Ultralast - UL-CRV3 - CRV3 Lithium Battery
Difference Between Lithium and Li-ion Batteries for Digital Cameras.Lithium and alkaline camera batteries are primary batteries and only designed for single use. Primary camera batteries cannot be recharged. Although the average cost-per-use will exceed the cost of rechargeables, they benefit from better single use performance and low self discharge characteristics. Low self discharge means that it can be store for extended period of time without losing its voltage or capacity.
Li-Ion and NiMH camera batteries are considered secondary batteries, which means that it can be recharged with its designated camera battery chargers. Heavy users such as professionals and avid enthusiasts will benefit from the economic cost-per-use value of rechargeable battery packs. However, rechargeable camera batteries will perform considerably less in comparison to its brethren primary batteries. Another benefit to rechargeable camera batteries is the benefit to the environment.
