Joblot, I use rechargeable batteries for most items and have a way to charge them in the car or house. The only exception are my LED ARC flashlight (torch) in which I am using regular batteries. I found the LED's don't seem as bright on the rechargeables (probably age) as they do on regular AAA's. I think I check my flashlights more often because of temperature extremes and because of using rechargeables. Overall I would say that I am checking or changing batteries about once a month. Other batteries also fall into the rechargeable category for use in 2-way radios and cellular phone. I haven’t used my PDA in a while and have “stored it” fully discharged. Lithium batteries do store longer, but I would recommend a schedule of monthly checking to avoid any problems.

During the month I also make an inspection of my fire extinguishers and smoke detectors. Imagine my surprise to recently find a “dead” smoke detector that had just checked out ok the previous month. In further checking I discovered the detector itself was defective and needed replacing. Since I live in a older home that has older wiring I knew I was running a risk without the detector. Hope this helps.

Take care,
Stargazer
