Digital camera batteries

Are you always running out of battery power just before you take that perfect picture with your digital camera? Here are some tips for everyone...

1) Turn off your digital camera when not in use.

2) Many digital cameras have a regular viewfinder and an LCD viewfinder. While thedigital LCD viewfinder has its benefits, it can drain battery power. Turn it off when applicable and use your regular viewfinder for taking pictures.

3) Don't stop after taking every photo and look at the picture in your digital camera's playback mode. Granted, you sometimes need to look at photos immediately after shooting them in order to make sure your exposure is correct, the lighting is ok, etc., but doing this does use up your digital camera's battery power.

Taking care of you new battery pack

Normally, a new battery pack comes in a very low charge condition and must be fully charged before use.
Your equipment may report a fully charge condition in as short as 10 to 15 minutes when the new battery pack is being charged for the first time. This is a normal phenomenon especially for Nickel Cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) chemistries. When this happens, remove the battery pack and let it cool down for about fifteen minutes then repeat the charging procedure. "Conditioning" (fully discharging and then fully charging) is necessary so as to maintain the optimum performance of a battery pack, and is recommended at least once a month articularly for Ni-Cd and Ni-MH batteries. Failure to do so could result in reduced charge capacity and can significantly shorten the battery packs useful life. Lithium Ion batteries do not require conditioning. It is normal for a battery pack to get warm when charging and during use. However, if the battery pack gets excessive hot, here may be a problem with the
portable electronic equipments charging circuit and should therefore be checked by a qualified technician. Rechargeable batteries undergo self-discharging when left unused for long periods of time.
