Controversial question I'm sure.

Good question, I'm not sure myself but I think it is important to keep them cool and dry. I've heard of people putting batteries in their fridgerators to prolong them but I'm not sure i would do that.
I never questioned why, but all chargeable batteries we have at work in storage get a float charge every 2 months according to guidelines that were established years ago. We take and record the voltage before, during, and after the charge. We also have to record the charge rate and temps. In addition, each has the voltage recorded weekly during storage.
Wet cell types (I know this doesn't apply) get periodic hydrometer readings for specific gravity. If any drop to a certain point withing a certain time frame, they get an equalize charge. If they don't meet certain requirements, they go as hazardous waste.
I guess when a piece of equipment gets the battery(s) replaced, they want to ensure the battery(s) are in a ready state and capable to meeting requirements.
At home, I keep my chargeable batteries in a charge state also. This not only applies to my "AA" NiMH, but my cordless power tools in the garage, jump start packs, ups systems etc.
Ni-CAD are prone to memory so I use NiMH for the detectors that accept NiMH. They exceed 2000 mAH ratings and have good run times. They do have a lower voltage of 1.2 volts per cell, so whatever equipment they are used in, the equipment voltage threshold of operation and total battery pack voltage must be taken into consideration.
I don't know how it all matters, but when I need to use a battery, I want it already charged - guess I better stop slapping my fingers on the key board............
