Query: good batteries, so-so charger

I got this set after reading some good reviews on the batteries and charger back in 2006. Since then, each set of 4 batteries were used together on Canon EX580 flash, charged together, and drained together.The other day, I picked up the BC9000 and put some "fully charged" powerex batteries, just off the MH charger, in to test. The BC9000 was able to put an extra 11-12% (~300mAh) into the batteries! Also, at least 1 of 4 batteries were at least 1% off in terms of mAh... Next, I'll be running some reconditioning tests to see...Bottom line - You are better off buying the BC-9000 for cheaper and buy 4 additional rechargeable AAs for comparable price, and you'll end up with 4 AAAs and some adapters on the side =)
