Rechargeable AAA NiMH batteries everActive EVHRL03-550 1.2V 550mAh pack of 4, cylindrical R03

Set of four everActive rechargeable AAA (R03) batteries EVHRL03-550 with Nickel-Metal Hydride (NiMH) chemistry. Each cell has a nominal voltage of 1.2 V, capacity of 550 mAh, cylindrical form factor and dimensions 44.5 x 10.5 x 10.5 mm with a weight of 9.5 g. Designed for repeated charging and use in everyday portable devices.

Advantages

Rechargeable NiMH chemistry reduces the need for single-use batteries and lowers long-term operating costs. Standard AAA (R03) size and cylindrical shape ensure compatibility with a wide range of consumer electronics. Moderate 550 mAh capacity provides reliable power for low- to medium-drain devices while the 1.2 V nominal voltage matches typical AAA battery requirements.

Suitable for

• TV and audio remote controls
• Children's toys and electronic games
• Clocks and small household timers
• Portable audio players, flashlights and other small electronics

How to use

Insert the batteries into the device following the polarity markings (+/−). Charge the batteries with a charger designed for NiMH rechargeable AAA cells and follow the charger manufacturer's instructions. After charging, install the cells in compatible devices and replace all cells in multi-cell packs at the same time to maintain balanced performance.

Usage recommendations

Store batteries in a cool, dry place and avoid prolonged exposure to high temperatures. For best cycle life, use a charger with temperature or delta-V cutoff suited for NiMH cells and avoid deep discharge. Replace the entire set when individual cell capacity noticeably declines.
