·          Rechargeable batteries typically last for 400-700 charge/recharge cycles.

·          It is best to have at least two sets of rechargeable batteries.

·          Use and recharge the same set of batteries together throughout their life.

·          Remove batteries when not using the camera for an extended period.

·          A set of AA lithium batteries makes a great backup since they have a shelf life of 10 years.

LiON – Lithium ion batteries are often used in the battery packs that come with a digital camera.  They last almost twice as long as Nickel Metal Hydride batteries (NiMH) but can be quite expensive and are not as common as AA NiMH type batteries.  So if you are in desperate need of batteries, you may not be able to find them quickly.

NiMH – Nickel Metal Hydride batteries are the most popular form of rechargeable batteries.  They do not have a memory effect, which means that they don’t need to be completely discharged before recharging.  NiMH batteries lose 5% of their charge per day when not in use.

NiCD – Nickel Cadmium batteries offer a great deal of power for a rechargeable battery.  They do suffer memory effect and must be discharged so they can accept a full charge.
