Batteries Don’t Dischange Equally
My good friend Dave recently emailed me something fascinating about how he goes through batteries like crazy. He has a daughter and many of her toys are battery powered, not to mention remotes and a host of other battery powered devices and appliances. The other week he managed to mix up some “good” batteries with fully discharged ones and, rather than recycle the entire bunch, he opted to test them… and discovered something very surprising:
I was thinking of you recently when I discovered a super easy way to be frugal… I have discovered that batteries (AA, AAA, C, D) in devices don’t all discharge at the same rate – I bought a battery tester a couple of weeks ago because I had accidentally mixed a whole bunch of batteries that were both good and “bad”. I thought that I had about 10 bad batteries out of the 20 I tested (10 were completely unused) but in reality, of the 10 that were “bad”, only 2 were fully discharged. The other 8 were still between full and half charged and as long as I removed the “dead” batteries, I could still use all the other batteries I had that I had origially planned on recycling.
