Best Buy offers the Panasonic Eneloop Multi-Pack Battery Kit (pictured), model no. K-KJ17MCC82A, for $29.99. (Amazon charges the same for Prime members.) Opt for in-store pickup to avoid the $5.99 shipping fee. That's the lowest total price we could find by $5, although we saw it for $2 less three weeks ago. It includes a 4-position charger, eight AA batteries, two AAA batteries, two C spacers, and two D spacers.
Also available at Best Buy is the Panasonic Eneloop Pro High Capacity Power Pack, model no. K-KJ17KHC82A, for $49.99 with free shipping. (It's available at Amazon for the same price.) That's $20 off and the lowest total price we could find, although it was $15 less a year ago. It charges up to four batteries simultaneously, LED display with status indicator lights, and overload protections. Eight AA batteries and two AAA batteries are included.
