Batteries

I use to fly radio control airplanes as a hobby a few years back. The batteries in the transmitter and in the planes tended to develop a memory if charged to frequently without a complete discharge and then they wouldn't completely charge unless recycled. Do the camera batteries like in my Cannon do the same thing? I have been putting them on charge everytime before I go out to shoot pictures.

no lithium ion batteries as well as nimh batteries do not develop a memory only nicd's do

Nickel-cadmiun (ni-cad) batteries will develop a memory. Nickel metal hydride (NiMH) batteries would only develop a memory if recycled after short usage and then only the earlier ones. Lithium-ion batteries will not develop a memory, but will last longer if deep cycled (allower to completely discharge and then recharged) periodically depending on use - anywhere from monthly to annually.

I have a fully charged spare battery on hand at all times and try to only charge the battery when it has around 30% power left.

Most of your camera batteries today are lithium ion. Your airplanes were likely nickel-cadmium. Ni-Cad was very bad about that. Lithium-ion are MUCH better but they aren't perfect. They will still eventually get memory loss but much, much, much slower. I've found this in lithium-ion power tools like drills, saws, etc. which get charged, run down, recharged, run down again daily or even more than once a day, which is far more activity than a camera battery usually gets.
Also, I've found that some (not all) aftermarket 3rd party overseas replacement battery companies make crap lithium-ion batteries that get memory quickly - sometimes as bad as nickel-cadmium. It wouldn't surprise me if they are advertising them as lithium-ion replacements without saying they're actually lithium ion, but using left over nickel-cadmium - that's how bad they are. I've had two that got memory and wouldn't even charge at all within 6 months of light use. So, to protect yourself, try to always use batteries by the company who made your camera.
