Increasing battery life... useful tips...
The following is the latest in the extremely helpful 'Weekly Tips' series from all-battery.com - [for link, see our margin].
"Does putting batteries in the freezer or refrigerator make them last longer?
It depends on which type of batteries and at what temperature you normally store them.
Alkaline batteries stored at "room temperature" will retain 90% of their power for years without refrigeration. Under normal circumstances, refrigerating or freezing alkaline batteries will extend their life by less than 5%.
NiMH and Nicd batteries, start to lose power when stored for only a few days at room temperature. But they will retain a 90% charge for several months if you keep them in the freezer after they are fully charged. If you do decide to store your charged NiMH cells in the freezer or refrigerator, make sure you keep them in tightly sealed bags so they stay dry. And you should also let them return to room temperature before using them."
