AA Size Battery Energy Requirement

muliply the amp hours of the cell by the voltage..

so a 4 amp hour AA cell give you 1.5V 6 watt hours.

then see how much energy it took to melt the zinc case, and the steel cover.

You will find it takes about 100 times the cells energy to create the cell. Dry cells are enormously inefficient, but they are portable.

Rechargeables change this since they can be recharged as many as 1000 times (varies a lot)

Thanks for the valuable info.The project is on emphasising the need of rechargeable batteries in lieu of AA size and hence want to prove the energy saved in manufacture of such batteries by using Ni-CD batteries.Thanks once again!

If you really want earthe friendly, try this multi use power supply:

Seriously, I will continue to purchase and use repeatable consistent life AA alkaline or better cells in my electronics.

If i fail to get the shot- (photo or bullet), because of earth friendly weenie- impotent rechargeables thst wimped out after a few short hours of standby/use I have lost my investment in my trip.

I have yet to see rechargeable batteries that approach the effectiveness of non rechargeables.

I have often been the one who got the shot (photo) because everybody elses rechargeables let them down by the early afternoon. And they didnt feel like packing along three more sets. I'm not likely to put rechargeablebatteries in my laser sight on my target pistol or sniper rifle either. Performance counts.

Price is an effective rationing method. If the work isn't critical- use rechargeables.

If it is critical, why use anything but the best?

Spare me the pagan gaia worship folks. The planet won't die because milo bought a couple hundred AA cells for his camera this year. They are the ideal technical solution for providing consistent electrical power in portable devices. Rechargeable are noble but insufficient means to do the same.

Any website(or reference), where I can get authenticated data to corroborate this!

So, are you planning on starting up your own plant?

It does not make sense to evaluate another companies energy usage in their requirements to manufacture a given product. The cost to manufacture AA batteries will also include the overhead to run the facillity, the cost of the man-power to get a finished product. Including every person in the loop. Office people, engineering, maintainance people to keep the place opperating, line people to actually do the required functions of running the equipement, and all the equipement to produce such an item. This complete loop is almost off the charts for the price of a single item sold at the local store for a $1.00 to the consumer.

If you take into concieration the actual availability of all the required equipement and energy required to make single battery, the outlay of the expended monies would be well over $100 Million out of pocket expences. Your equipement would need to be able to produce X amount batteries per minute to have a proffit margine of any sizable amount to cover the overhead alone in production. To even concider the rational equation is a waste of time IMO.

Concider the break even mark in recapturing the monies spent to just get started, 10 years of producing 25 AA-batteries per minute, 24/7? That comes to ~1500per hour, 36000 per day, 13,140,000 per year. Now take all the people required to run the facility, the equipement, the warehouse after packaging, the trucks to deliver. Then add the power consumption to run the facility. Your actual profit gain would only be, maybe, this would be rough guess, less then ~8% after everything is paid for. Now this would take into account of the rejects from start to finish. Anything can go wrong with such a major opperation.

Now to be required to do a statiscal report on the actual energy spent, or the possible savings is completly a waste of your time and who ever concieved this idea or report needs to open their eyes in the reality of such a report.

Contac Duracel Corp., and get in touch with their bean counters...they would have the actual numbers your boss is asking for. They may fudge the true findings to throw you guys off as well. Good luck, and sorry for the rant, but reality is reality in the manufacturing world. Maximo

From reading this Thread I got one more nail in my coffin of batteries.

My obsession with batteries is increasing. I am in love with batteries.

The bigger & rounder and heavier, the more powerful, the better.

& Then it comes to be that the PreCharged Rechargable Battery is the greatest thing

since sliced bread.

Next, I will become as the Blood Battery and it will run my exoskeleton skin when I am at work.

With the aluminum foil from my sandwich, a nail, and some dirt and paper, I expect power to flow out of the grip of my regular sized hand.

All power to the battery!
