Maha MHC401F-S4AA25, Charger with Four "AA" Rechargeable batteries

The PowerEx MH-C401FS delivers the most complete charge for chargers in its class. Unlike other fast chargers, the PowerEx MH-C401FS allows you to recharge AA & AAA NiMH or NiCD batteries accurately and coolly, around 100 minutes (AAA charges in around 1 hour).

Unique FLEX negative pulse charging algorithm allow the battery to accept a more complete charge and significantly enhances battery life regardless of the battery’s capacity. If they can't be fully charged users would not be able to fully realize the potential of their batteries.

FLEX Pulse also makes traditional "battery conditioning & cycling" unnecessary as the pulse eliminates the memory effect just by charging the batteries. Manually switch between 100 minute fast charge and 5 hour gentle charge.

The MH-C401FS is also the first charger on the market to offer the choice between a 100-minute rapid charge and a slower, gentler 5-hour charge, both driven by a microprocessor termination control to prevent overcharge. Accomplished by simply flipping a switch, the 5 hour gentle charge achieves ultra-cool charging when charging time is not crucial.
