Yes, but only if they can be kept dry as well. The higher the temperature, the more the free flow of ions or self-discharge from the battery. Storing primary batteries (D's, C's, AA's, AAA's, 9 volt, etc.) in a cooler environment slows down this rate of discharge that all batteries experience even when not in use, hence a longer shelf life. However, if this is done, it is important that the batteries be kept as dry as possible by keeping them in an airtight container in the driest part of the refrigerator, the door side for example. Long time exposure to moisture inside the refrigerator can cause internal corrosion to the battery. When removing batteries from the refrigerator, allow them to warm up to room temperature before using them in your device. Can I use my old version Ni-Cd battery charger to charge my Ni-MH batteries? No, you can use a new Ni-MH charger to charge your old Ni-Cd batteries but you should not try to charge Ni-MH batteries with a Ni-Cd charger. Here's why: Ni-MH and Ni-Cd batteries are chemically very similar and when both are fully charged the battery voltage will start to drop. The Ni-MH voltage drop is much more subtle and more difficult to detect. Ni-MH chargers usually have an over-temperature sensor and shutoff to prevent overcharge as well as a more sensitive voltage drop detector where Ni-Cd chargers usually only use the voltage drop to determine when to stop charging. If you charge Ni-MH batteries in a Ni-Cd charger it will probably miss the voltage drop and keep right on charging causing the batteries to overheat. Overcharging and overheating Ni-MH batteries can damage them internally and reduce battery life. My new laptop and/or camcorder battery is not working at all! What's up? New batteries are shipped in a discharged condition and must BE charged before use. We generally recommend an overnight charge (approximately twelve hours) for Ni-Cd batteries and a 24-hour charge for Nickel Metal Hydride. Refer to your computer manual for charging instructions. Rechargeable batteries should be cycled - fully charged and then fully discharged - 2 to 4 times initially to allow them to reach their full capacity. (Note: it is perfectly normal for a battery to become warm to the touch during charging and discharging). more info:http://www.good-battery.com
