I used coconut battery for about a year now and it was great in 2.5 and 2.5.1. But I upadated it to 2.6.1 (didn't use 2.6) and now it's a CPU hog. When i start up coconut battery on my C2D Macbook the system% goes from 1-3% up to 75-83%. I did not notice this in 2.5 version. I checked activity monitor and there are about 12-13 ioreg processes listed. Most of these ioreg's range from 8-12% with a few at 1-2%. It cause my cpu temp to jump 10-15 degrees celsius and my fans to increase.

This should not happen with a simple battery monitor.

I'm using leopard though that should be a factor since 2.6 and on was suppose to be leopard compatible.
