OT: Dry cell batteries - what do YOU buy? WHY?

Went to Wally World t-nite... one of the items I needed were some AAA batteries. As always, I am always wondering which brand to buy... EverReady, DuraCell, RayoVac, or WalMart's store brand, EverActive??? [img]/ubbthreads/images/graemlins/wall.gif[/img] The EverReadys & Duracells are exact same price..., RayoVac a mite less, and EverActive lowest price (per unit). THEN... I see there are "new, improved" batteries for electronic devices. [img]/ubbthreads/images/graemlins/deal.gif[/img]

They're all alkaline (I guess)... so is there a 'better' battery? Or is it just another way of gouging a few more dollars outa the consumer(s)?

Is there an (easy) way (for us unsophisticated types) to test dry cells to quantify the power therein? Or, a good - unbiased by commercial interests - consumer report these thangs?

Enquiring minds want to know!

I buy the least expensive, of course!

Re: OT: Dry cell batteries - what do YOU buy? WHY?

In most cases I'd say the cheaper the better..

BUT.. if you have a big 3D cell maglite.. try loading it up with the dollar store brand ones.. and then try with a new set of duracels.. you will definitely see the diference..

But, in most cases i use the cheap ones.. but for my flashlight and a few other select items I use the Duracels.

Re: OT: Dry cell batteries - what do YOU buy? WHY?

I get batteries from this guy who comes around my job selling bootleg cd's and dvd's and they say duraking on them. They seem to work fine. Batteries are batteries I guess until you start getting into lithium and rechargable ni-cad types. Then I'm certainly not the battery guru.

Re: OT: Dry cell batteries - what do YOU buy? WHY?

Wondered myself.

I tried something - voltmeter on 10 Amps.
Hooked it directly to + and -. That's a short across the battery.
Tested the cheapie's - did about 3 amps.
Duracell - 5-6 amps
Energizers - 6-8 amps!
Downright impressive to see that much short circuit current out of a little AA.

What does that say? Dunno, except on a short term basis the Energizer can put out more current.
--- But most devices don't use or need that much all at once.

How long do they last? Dunno! Others may not put out that much on a short term basis, but may last longer.

Re: OT: Dry cell batteries - what do YOU buy? WHY?

Costco's Kirkland brand.....they are made by EverReady

And congrats RRich.....you just did one of the main tests they do on batteries...called the internal resistance test...the lower the internal resistance, the more amps it can deliver...

Next is the capacity....if it's a 250ma/hr battery, put a 250ma load on it for one hour...if the battery voltage is at or above .9 volts after that time...it passes.

Always was partial to duracels. They used to work the longest in my wireless for my guitar/amp. They last thing you wanted was to be onstage in front of a big crowd and not have any guitar. So I always stayed with them.

Re: OT: Dry cell batteries - what do YOU buy? WHY?

There was a TV News magazine show about this... they tested lots of different labels. Likely was a couple years ago but I found it worth watching.

The funny thing was that many of the off brand batteries were made in the same factory by the same specs. as the name brand, but sold for less. It seemed to come down to shelf life and distribution chain time when comparing typical alkaline AAA, AA, C or D cells.

At one point Duracell had a use before date.

So why did they stop putting those little testers on the package?

Why is it that Duracell and Energizer batteries are price fixed?

While I normally just buy the Duracell or Energizer batteries... the Drug Store brand might be just as good if they are fresh.

Why did you make me think about this Jerry? [img]/ubbthreads/images/graemlins/confused.gif[/img]

WalMart needs to fix the whole thing by buying Duracell and Energizer, making them both cheaper without a change in quality. [img]/ubbthreads/images/graemlins/smirk.gif[/img]

Re: OT: Dry cell batteries - what do YOU buy? WHY?

The best batteries I've ever found.....by far are the Kodak Brand of batteries. I used to get them at Dollar General for like 1.50 for a 8 pack of AA's. They ou lasted the energizers and duracells etc by at least 2:1
