2450 mAh AA NiMH Energizer Rechargeable Batteries

How Energizer Rechargeable Batteries work.

  Like primary batteries, rechargeable batteries have four basic components—a positive electrode (cathode), a negative electrode (anode), a separator and electrolytes. But that’s where the similarities end. The chemicals inside a rechargeable battery are reversible, allowing them to be recharged again and again—the Energizer Rechargeable Nickel Metal Hydride AA battery, for example, can be recharged up to 1000 times. Energizer Rechargeable batteries offer good performance and cost less per usage than their alkaline counterparts.

  Energizer Rechargeable batteries are ideal for high drain devices that use a lot of power. But they should never be used in smoke detectors and are not recommended in other low drain devices. Here’s why: Primary batteries are—turned on— when they’re inside a device and the device is operating. But rechargeable batteries lose some of their power everyday, whether they are in a device or not—so it’s important to re-charge them often to maintain maximum capacity.
