Rechargeable Batteries

In honour of Earth Week, here’s some interesting information on rechargeable batteries.

Adventures in Rechargeable Batteries

I’ve started using the charger talked about (The LaCrosse BC-900), and am quite impressed with it. One thing I like is the solution to C/D batteries. Instead of having to deal with all these different batteries, the charger came with adapters. You places a AA inside an adapter sized like a C cell. If you want a D cell, then you place the C cell adapter inside a D cell adapter. Means you only have to worry about 2 kinds of batteries (or if you don’t have anything with AAA, then 1).

I don’t have any hard evidence about the batteries themselves, but the charger is great. Discovered that some old rechargeables I have around the home only hold about 250mAH these days, even thought they’re rated at 2500mAH…

Another great charger maker is Maha. They’re a little more expensive, but look to have a few more features.

A very interesting article over at Coding Horror about rechargeable batteries, and the games the manufacturers play (although they do it in all industries. Megapixels for cameras, GHz for computers, HP for cars…).

A good place to buy is Thomas Distributing. That’s where I ordered my charger, as I live in Canada, and Amazon.ca doesn’t carry electronics. I got mine on sale, so it was less expensive than Amazon anyway.

I’ve ordered the La Crosse Technology BC-900, so expect a followup post once I’m done. One nice thing is it contains adaptors for C and D batteries. You put AA batteries into the adaptors to power items that require the larger batteries. Very nice!
