So you’ve got your AA-battery flashlight (maybe even TM’s #3 favorite; see 11/12/09), or your AA-battery digicam for those shop shots, or a  Minty Boost (TM 7/10/09), or any of the approximately eleventy bazillion things around the house that use AA or AAA batteries, and you’d like to use NiMH rechargeables instead of going through packs of alkalines. The Maha Energy PowerEx MH-C9000 is a charger and analyzer for NiMH and NiCd AA and AAA batteries. Its four independent slots have five modes of operation: charge (at a selected rate), discharge (at a selected rate), cycle (perform discharge/charge up to 12 times), break-in (charge at 0.1C for 16 hours, rest for one hour, discharge at 0.2C, and finally recharge at 0.1C for 16 hours; for new batteries and those stored for more than three months), and refresh & analyze (charge, rest for one hour, discharge, rest, and recharge; for batteries stored more than two weeks but less than three months, or for batteries showing poor performance; the refresh & analyze mode can also be used to select and match battery capacities). The MH-C9000’s digital display shows capacity, voltage, time, and current. The unit has many, many programming options (a bone of contention in some reviews).

The MH-C9000 costs around $50 (and some vendors, like Thomas Distributing, often have sales that include a carrying case or batteries).
