NIMH AA Batteries

While I’m a big fan of rechargeable NiMH AA batteries, I’ve noticed something odd (and quite honestly, disappointing) in the last few months. A bunch of the NiMH AA batteries here at ranchero indebto are draining awfully quickly. This problem  cropped up with the NiMHs that are installed in our programmable thermostat … within weeks of swapping in a freshly charged set of AAs, the “replace battery” warning began flashing.

I swapped in another set and the scenario repeated itself, leading me to believe that I’ve got a bad batch of AA NiMHs. While it’s impossible to tell the state of charge without a battery tester, I’d reckon that this handful of (expensive!) batteries is discharging way faster then they should.  We haven’t gotten 100s of charge cycles out of the batch … only a few dozen.

After it happened again this week, I got off my duff and did something.

I’m not turning my back on the technology … just switching brands. After doing a bit of research, I decided it was time to pick up a dozen Sanyo eneloops AAs, but I couldn’t find a store that carried them locally.

Amazon to the rescue.

I found an Amazon merchant with a remarkably low price, but quickly found out why their price was so low … they were charging $3.99 shipping and handling for every item. When I went back to the main sales page, I noticed that the Sanyo eneloop AAs were eligible for free super saver shipping, with a minimum $25 order.

With a trio of four packs I landed three dollar savings over the lowball price and never had to leave my desk…

    Where is the rest of the article? With the article ending the way it did, it was no more than a glorified advertisement for Sanyo!

    Where’s the meat, so to speak?

    @Lou – Many thanks for your thoughts, but I’ve never gone out of my way to write glorified advertisements. :)

    The Eneloops worked as they should, right out of the packaging. They’ve been installed for a few weeks now in our programmable thermostat and in a couple of remote controls.

    I’ll update the article once they hit their first recharge cycle.

    Thanks for the info, Matt, especially about Podtrac and Blubrry. I’ve been trying to get more listeners (and advertisers) for my podcast, but on my own, I would have never known about these services.
