Choose the reliable Energizer Maxi battery charger to keep your essential devices running at maximum performance. Perfect for your most-used gadgets, like remotes, computer mice and gaming controllers. This handy device charges 2 or 4 AA or AAA NiMH batteries in as few as 5 hours (for 500 mAh AAA batteries). Charge times vary by NiMH battery type. The charger comes with 4x 2000 mAh NiMH 1.2V AA Energizer Recharge Power Plus Batteries. Simply load up the rechargeable battery charger and plug it in for fully-loaded power when you need it. The charger’s indicator screen will change from red to green when your batteries are fully charged, and the Delta V cut off feature prevents overcharge. If a bad or primary battery is detected in the device, the screen will pulse to notify you. Since creating the world’s original consumer battery in 1896, Energizer has led the charge in industry innovation with a proud history of firsts, including the world’s first on-battery tester. The brand brings this forward thinking to environmental initiatives too, developing the first ever rechargeable battery system in 1958 and introducing the first zero-added mercury battery in 1989. Energizer Recharge batteries were also the first rechargeable to contain recycled batteries. The company partners with organisations that encourage, inform and empower consumers to recycle non-rechargeable batteries, as well as battery packaging.
