I second that ....

It makes restocking easier. Instead of going to the store and buying 2 AAA, 4AA, 6 coin cell of varying types, 2D and 1 9v you just buy one bulk pack of AA.

AAAA's are actually easy to find. Rip apart most 9v batteries and you get 6.

thats not with all 9 volts. Also they are usually slightly shorter so you need a spacer.

I've standardized on AAA for EDC and PSK where weight is important and AA for most other gear.
Have a small AAA radio, Arc AAA, AAA minimags, AA minimags, AA digicam, etc. I have a few Lithium AA batteries stocked and 10 NiMH AA rechargeable and a charger that will charge AA and AAA NiMh and NiCad and will charge from 120 or 12v. Buy the regular AA's and AAA's in the 16 count bulk packs for about $10. I gave away mu D call mag light and anything that takes those stupid coin cells that don't last more than a few days when they are actually used. The only thing now in the house that takes anything else is the two smoke detectors which take 9v batteries, the keyless entry fob for my truck and my 9.6v Cordless drills/saws/flashlight but those have their own special rechargeable.

Yes not all, but it seems that most of the brand names do.
As long as its one or two cells then the device they are going into usually the spring gives enough flex for the slight shortness.

Almost all my gear is AA power, or I have a backup that is AA powered in my EDC kit. The exceptions?

Arc AAA flashlights (AAA cells) - but the AA has replaced the AAA on my keyring - may shift back due to size

My EDC60 light - that takes a CR123, and I'm NOT happy about that. The are supposed to come out with a AA tailpack, and that pack WILL go in my EDC bag, but the flashlight will stay in the pocket with the CR123 - this is backed up with an Arc LS "first run" with 2xAA twisty. ONLY 30 lumens, but....

Other than that, it's all AA - including the HT, which has a rechargeable and AA packs with it

oops, I forgot about my glo-toob lights too, so I have to join John's club of AA or 123A or AAA or 23A or NO WAY catagory! I know the photon lights are a staple of almost everybody's edc, but I stay away from the button batteries, I just hate those button batteries.

>> You should also look at the actual mAh available from each cell.<<

I did. That's how I calculated the "power density" for the various cells.

Off the top of my head, the D cells are rated at over 20,000 mAh, C cells at a little over 8,000 mAh, AA at a little under 3,000 mAh for alkaline and 3,000 mAh for Li, etc. See the Energizer site for details.

There's not a lot we can do except not buying the products that are not what we want them to be. <img src="/images/graemlins/smile.gif" alt="" />

Most of the gear I am using takes either AAs or AAAs (Petzl lamp, flashlights, digital camera, etc.). That did not prevent me from buying a Motorola V400 phone ;-)

As long as the cell format isn't something very weird or unusual, I don't really mind. Sometimes you don't have the choice (My Nissan car remote takes a coin-sized battery, my Astrostart remote takes another kind that's half the length of an AAA, etc.) but when I have the choice, I purchase AA or AAA stuff.

My 2 cents!
