A note about included batteries. They seem to be the older kind of Rayovac batteries. The newest latest and greatest Rayovac batteries are called "Hybrid" and are really really good!
The main difference: self discharge rate!
- The regular NiMH batteries (which you get with this) are great for immediate use after the charge (slip them in your camera and shoot away!), but they have poor shelf life, and tend to lose up to 1/3 of a charge over just a few weeks of storage.
- The new Hybrid NiMH batteries have slightly lower capacity, but they can be stored and used over long periods of time, with very slow self-discharge, something like 10% over 6 months, if I'm remembering the numbers correctly!
