Great deal! Rechargables? Watch out for lower voltage!Tuesday, March 22, 2005
Great deal, now at 20ยข each.
When thinking about rechargeable batteries,
be aware that many (if not all) have a full
charge voltage of 1.25V, while the alkalines
have 1.5V -- some equipment, like the flash
attachment on my digital camera, will NOT work
with 4 rechargeable batteries (5V) but WILL WORK
with 4 alkalines (6V). Test before making major
purchases...

Sina is right - in some casesSaturday, March 05, 2005

Rechargeables are unquestionably the best choice for devices like toys, CD players and digital cameras that need fresh batteries frequently.
Simple arithmetic makes the case:
Conservatively assuming a charged NiMH cell holds -- on average over its usable life of 500 charges -- half the usable energy (watt-hours) of the best NEW disposable AA alkaline cell, Compare costs:
48 disposable AA cells = 8.99 (cheapest "Tech B" brand)
so 480 disposable AA cells = 89.90
can be replaced by
2 rechargeable AA NiMH cells = less than 10.00 (for top brands like Sanyo or Sony or Duracell)
So about 90.00 worth (at a super bargain price) of AA alkaline cells can be replaced by less than 10.00 worth (at everyday price) of rechargeable NiMH AA cells. The same or better ratio is true for AAA cells.
So unless you're on unmotorized safari in darkest Africa, or stuffing AA cells into junk that'll soon be lost or carelessly discarded, or replacing the battery in your wall clock every six months (in which case your rechargeable AA would last about 125 years), the choice here is a "no-brainer".

On rechargeable batteriesTuesday, February 08, 2005
In response to Sina Neshatian (1/16/05): I gave up on NiMH rechargeable batteries because: 1) They don't take as much charge as alkaline, even when brand new; and 2) They run down far more quickly. I think they would be very appropriate for uses less demanding than mine.

Non-rechargeable batteries??? What???Sunday, January 16, 2005
Why the deuce would anyone buy batteries that are not rechargeable??? They would pay for themselves dozens of times in a lifetime, and they will potentially save waste. It's like people buying cell phones that had to have their batteries replaced every time they ran out. It's absolutely ludicrous.

Good BatteriesSaturday, January 15, 2005
These batteries last as long as the name brands. We use these in pager, book lights, and a few different types of medical diagnostic equipment, without any problems.
Consumer reports did a study on alkaline batteries and found them all to be pretty much the same, no matter where they were made, or how much they cost.
So save your self some money.
