Battery charger everActive UC-4000 for AA/AAA household batteries, 4-slot, 100–240V, black

The Everactive UC-4000 Household Battery AC charger is a multi-chemistry charging device intended for home use. It supports Lithium Iron Phosphate (LiFePO4), Lithium Polymer (LiPo), Lithium-Ion (Li-Ion) and Nickel-Metal Hydride (NiMH) battery chemistries. The charger operates at a charging voltage of 12V and provides up to 3A charging current. The unit's compact black housing fits typical household environments and accommodates standard AA and AAA cells, with capacity to hold multiple batteries simultaneously for convenient replenishment.

Advantages

The charger accepts several widely used battery technologies, allowing one device to service different types of rechargeable cells. A 12V/3A charging specification offers a balance between charging speed and thermal management suitable for everyday use. Its ability to handle AA and AAA sizes and multiple cells at once reduces the need for extra chargers and simplifies battery maintenance. The black enclosure provides a neutral appearance that integrates easily into home settings.

How to use

Place the charger on a stable, non-flammable surface and connect it to a suitable mains outlet. Insert batteries according to their size and polarity markings; ensure correct orientation before starting charging. Select the appropriate chemistry or charging mode if the charger requires manual selection, and begin the charge cycle. Observe the charger's indicators to confirm charging status and wait until the cycle completes before removing batteries.

Recommendations

Use the Everactive UC-4000 in a well-ventilated area and avoid covering the device during operation. Only charge batteries of the types and sizes specified, and do not mix damaged or leaking cells with good ones. Follow manufacturer guidelines for individual battery chemistries—for example, use appropriate charge profiles for LiFePO4, LiPo and Li-Ion cells. Disconnect the charger from mains when not in use.
