This short instructable will show you how a person can get free usable batteries, possibly delivered right to them.  

Not only can free batteries be had, but the environment can be helped as well.  This is especially useful for charities and non-profits, which can go through a lot of batteries through their course of operations.

There is some time and work involved, so although the batteries are free, an investment of time and sweat can easily give them value.  

For some people, the amount of work and the time involved may not seem worth it.  Those who feel this way should go ahead and purchase batteries as they have been doing.  However, I would encourage people to purchase rechargeable batteries and a charger instead of the single use ones. Everyone should read through this short instructable, however.  Money can be saved by eliminating the tossing out of good batteries or wasting time while attempting to use dead batteries in a device.  

Everyone should recycle all household batteries instead of throwing them into the trash, where they will end up in landfill.  Most batteries contain heavy metals and other materials that can be recycled.  When thrown away, they can pose a risk to the environment and our health if allowed to break down and leak out into the ground.

Step 1: Purchase a Battery Tester

I purchased the battery tester below for about $3 from an online source.  At the time of this writing this type of battery tester was available on www.Amazon.com for about that price.  Search for SE Battery Tester in order to locate one online.

This type of battery tester is good for checking small household batteries, like AA, AAA, C, D, 9V, button, etc. Household batteries that are called heavy duty, alkaline and so forth are good for this test, but lead-acid batteries should not be tested this way.

Alternatively, if you own a multi-meter, you can use it to test most household batteries as well, but the battery tester makes it much faster and easier.

<p>I have an L.E.D. torch that uses AA batteries, awhile back after putting new batteries in my dim torch I checked the old ones with a multi-meter and they were still showing some voltage. I've since found that the batteries I thought were &quot;dead&quot; will go into a battery clock and last for quite few months longer, same goes with the &quot;dead&quot; batteries from my TV remote! Following your tip though and slowly changing them all out to rechargables.</p>
<p>Really nice idea!</p><p>You can also recharge Alkalines to a certain extent with low, about 50mA, IF they are not too low before. Just treat them like RAM.</p><p>:-)</p>
holymoses,<br><br>Thanks! I should re-write or update this Instructable. If I do, I'll include your tip!
Don&acute;t get me wrong, you cannot refresh them to new quality.<br>Just make some own tests, you can push them a little higher than they were before. It is just a myth that alkalines would explode being recharged, if they are too old or too deep discharged before then they might show some leakage, that&acute;s all.<br>:-)
<p>Don't forget to store batteries in non-metal containers. Also check to make sure the positive and negative sides are stored in such a way to avoid batteries from heating up and starting a fire. I recently saw a video on someone recycling 9 volts and how they just tossed them into a box in the laundry room. The batteries fell into a position that caused the terminals to touch and it started a fire that almost burned their whole house down.</p>
be easier to buy new ones
You can pick up free AA batteries out of disposable cameras--check out places that develop film.
That is a good tip! Thanks for sharing it here.
Great post. So simple and yet something I haven't thought of doing. I think sometimes we forget that just because a battery doesn't have enough juice for its original purpose doesn't mean it can't power something with less power needs. Green isn't any good if its not practical, this is practical and save green too! Thanks.
