Title: Seems to do what it says
Review: The batteries that come with this set work great. I was really happy with the longevity, though the Canon S2 IS I used them with purportedly has good battery usage. The charger is a bit large, and hence when I was trying to pack efficiently for a big holiday, I opted to take my smaller 6 hour charger instead. I supppose that the charger needs to be big since there is a built in fan to help cool the batteries as they charge. It is convenient to know that I can get fresh batteries quickly. Now, I only have to charge them within the 30 minutes before I leave instead of all night. I prop the charger against the wall at an angle to get better air circulation around the batteries.
