16-Slot charger with bundled AA cells

The Tenergy TN438 is a 16-bay smart charger supplied with 16 AA NiMH cells rated at 2500mAh each. It accepts AA and AAA NiMH or NiCd batteries and is suited for households that run many remotes, controllers, keyboards, mice, clocks or toys. The worldwide AC input of 100V to 240V at 50Hz or 60Hz lets it operate on any mains supply.

Per-bay LCD status and safety features

Each of the 16 slots has its own LCD segment showing charge or discharge progress for the individual cell. Smart circuitry guards against overheating, reverse polarity and enforces an 8-hour safety timer. A refresh button initiates a full discharge before recharging to help maintain capacity. The unit measures 12 by 4.1 by 1.2 inches and weighs 14.5 ounces without batteries.

Button-top requirement and fixed charge rates

The charger only works with button-top rechargeable cells; flat-top batteries will not make contact. Normal charging current is fixed at 500mA for AA and 250mA for AAA, while discharge runs at 200 to 300mA. Users needing faster top-ups, USB output or mixed-chemistry support must look elsewhere.
