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.
