I've already written about a variety of Eneloop rechargeable batteries. I have given them all high rankings and strong recommendations. Frankly, I surprised myself by spending the extra money for colorful batteries. So I realize these aren't for everyone. For the practical-minded, the regular Eneloop batteries are wonderful. But if you want all the virtues of Sanyo's uber battery line and have them look great in your drawer or your devices, you will be very pleased with these.
