I buy as many things as I can based on a common battery type. I try to stay with devices that use AAs and D batteries, but have a few things that come in C size batteries.


But you can’t do that with rechargeable items as easily. My cell phone and Palm Pilot have internal rechargeable batteries and I can’t get around that.

I refuse to buy anything that runs on the CR-123 batteries as they are expensive compared to AAs and I don’t feel they give much advantage for a flashlight. I have some fairly bright flashlights that run from AAs and C batteries. My digital camera runs from AAs, I made a battery charger / pack for my Palm Pilot that runs on 4 D batteries (also charges and runs my cell phone) so I standardized the rechargeable batts to run on a common battery.

I also have 12-volt chargers to run things so I guess you could say I standardized lots of things to run from a common voltage source.
