EOS Canon Camera batteriesA short guide to the range of batteries used in Canon EOS DSLR camerasCanon cameras use a range of batteries for main camera functions and back-up. This info page contains camera battery types and associated information. Hope it helps if you are looking for a replacement camera battery.. 2008 News. There are new US regulations for carrying lithium batteries on planes See here for detailed listings (see below for lithium values for LP-E4 and BP511A) "The following rules apply to the spare lithium batteries you carry with you in case the battery in a device runs low: Spare batteries are the batteries you carry separately from the devices they power. When batteries are installed in a device, they are not considered spare batteries. You may not pack a spare lithium battery in your checked baggage. You may bring spare lithium batteries with you in carry-on baggage. Even though we recommend carrying your devices with you in carry-on baggage as well, if you must bring one in checked baggage, you may check it with the batteries installed."
The What's New Page gives a quick overview of the hundreds of pages of articles and picture on this site.

Refreshing batteries and the memory effectSometimes a problem with older NiCad batteries, and much more rarely so with NiMH types, this is not a problem with Li-ion types. It's worth noting that the 'memory effect' in rechargeable batteries was rarely as common a problem as many posts on camera forums might suggest - many people forget that they do have a limited lifetime :-) With NiMH cells they are often helped by a full discharge and subsequent recharge. With NP-E3 cells you can press the 'refresh' button on the NC-E2 charger The new LP-E4 packs can also be refreshed, which although not to fix any memory effect, does help maximise battery performance. If your charger doesn't have a refresh option then you can safely fully discharge a battery pack by turning off the auto shutdown feature of your camera and leaving it switched on until it shuts down. Replacement batteriesThere are a lot of cheap camera batteries available from places such as eBay. Be very careful if you buy cheap replacement batteries off the net. At best, many have much less capacity than advertised, and at worst they may represent a fire hazard. To see the sort of variation you can get in camera battery performance see the second link below.
