Whoa, thats pretty sweet! Do you if the batteries last as long as their expensive counterparts?

you can save even more money if you do this with a car battery, which is 12 volts also. however, because car batteries contain much more energy, you want to partially discharge it first! the best way to do this is to take a metal bar and put it across the battery terminals for ten minutes or so. then use the claw part of a hammer to crack it open so you can remove the individual cells. make sure you do all of this outside, as it will be a bit messy.

h2so4...if it is a car or acid based battery..

That video sounds just like an infomercial - I kept waiting for the "and if you call now, we'll throw in..."

Where would I find the vidio for this. I dont understand how this would work.
thanks

Before I go cutting open batteries, I wonder if this hack only applies to the Energizer brand or with cheaper no-name or from China Batteries?

When you disassemble a 12 battery you get eight 1.5 volt alkaline button cells with a capacity of 0.028 Amp-hr. each.
I know this because I 've disassembled more than 60,000 of them yielding a half million button cells.
Believe me, It has saved me some serious money!

You know - I think next when I need button batteries that I shall dismember some A23s. Also, as a point totally unrelated to batteries, This video was on the end of video 'suggestions list'. Very nice it is too, whilst being completely scientific of course ;-)

Bravo on batteries though!

Some handy info to know, save some cash.

Thanks for the info, Guest. You mademe reevaluate the current battery market.

Still, I'm talking from a military standpoint where you have to have batteries, right now, so you walk into Wally-World with the unit MPACT card.

Or anyone else, of course, who maybe can't wait for an order to arrive.

Do you have the Speech Synthezier or Hunt the Wumpus on your TI994A? How the heck do you use those little batteries to power it? Are you talking about the clock batter?

WHAT DID YOU SAY? : )

good to know - i'll keep that in mind. last time i needed some of those 1.5V batteries we just ordered them on ebay - for pretty cheap.

It was a rainy day, they were there, so...

Definitely worth knowing. I have a couple of the A23 batteries. I'm going to have to check it out.

first of all IDIOT, car batteries are Wet Cell. all the batteries we use in our electronics are dry cell.

and cracking open a car battery could KILL you! There's far more Amps in a car battery than in these things.

You must be a moron! Go ahead and try this, we need to rid the world of morons....in about 2 minutes or less after you short the battery with the metal rod, it will explode. But go ahead.

OK guys, this is called a "hoax" ...

Having a larger chemical cell would be the most profitable and logical design choice for the battery makers
NOT including smaller button cells.

something about reading this page, watching those videos, and reading the comments makes me think that people are idiots. Seriously.

Got 40 of those batteries for a total of $8 (including S/H) off of ebay. A little bit easier that way...

Energizer batteries are made in the US or Japan, except for A23, ehich clearly says "Made in China for Eveready." The little cells inside are chinese made generics / oem, with nowhere near the lasting capacity of regular Energizer made button cells. You get what you pay for :) .

Um, someone please delete that comment before someone hurts themselves. I know for a fact that the batt will explode if you short it out. The heat generated by the rapid discharge of the batt will weld the piece of metal to it pertinently which puts it in an unending loop of short out batt heat up bar, short out batt heat up bar and will eventually overheat the batt and cause it to explode!

Having a single larger cell is not more cost effective. Especially since the "standard" battery dimensions were developed in exactly this way. All batteries are made up of "cells". IT just so happens that some of those cells are finished products in and of themselves. It's very costly to design a new product, let alone gear up to manufacture it. A company can save a lot of money whenever they combine existing, readily available, components to produce a product- whether those components are something they produce, or something they buy from someone else. They don't have to build a substantial new manufacturing line, and they only have to engineer the "wrapper", so to speak. Also, there are specific performance benefits that can be achieved by putting existing battery cells together in different ways. You might be trying to achieve longer runtime, or higher initial current, etc., etc., etc.

So, don't be too quick to disbelieve, all of you who don't work in product design or manufacturing...

hahaha morons
