Rechargeable AAA Battery Duracell BUN0043A NiMH 800 mAh 8-pack

Rechargeable AAA Battery Duracell BUN0043A NiMH 800 mAh 8-pack are Nickel‑Metal Hydride (NiMH) cells with a nominal capacity of 800 mAh supplied as an eight‑piece set. These Duracell Pre‑Charged batteries arrive ready to use straight from the pack and are designed for multiple charge cycles. They target everyday household electronics and provide a reusable alternative to single‑use alkaline cells while retaining most of their charge during storage.

Advantages

These AAA NiMH batteries offer a balance between energy capacity and compact size, suitable for low- to medium-drain devices. Pre‑charged technology reduces the need for initial charging before first use and the low self-discharge specification means up to 95% of charge is retained in the pack for up to 12 months. Duracell states the cells can be recharged thousands of times and are compatible with Duracell battery chargers, which reduces the environmental impact and long‑term cost compared with disposables.

Suitable for

• TV and AV remote controls
• Children’s toys and handheld games
• Wireless mice and keyboards
• Portable torches and LED flashlights
• Small household gadgets such as clocks and calculators

When it may not be suitable

These 800 mAh AAA NiMH cells are intended for devices with low to moderate current draws. For very high-drain devices or applications that require the longest runtime between charges (for example high-power camera flashes or some motorised tools), higher-capacity cells or specific lithium rechargeable options may perform better. They are also not suitable where single-use alkaline chemistry is explicitly required by the device manufacturer.

Key specifications

• Battery chemistry: Nickel‑Metal Hydride (NiMH)
• Cell size: AAA
• Nominal capacity: 800 mAh
• Pack quantity: 8 cells
• Pre‑charged with low self-discharge: retains up to 95% charge for up to 12 months in pack
• Rechargeable: designed for thousands of recharge cycles
• Compatibility: compatible with Duracell battery chargers and standard NiMH chargers

How to use

Install the AAA cells observing the device polarity markings (+/−). For best performance in multi‑battery devices, use cells from the same pack and with similar charge state. If a charger is required, use a charger compatible with NiMH chemistry and follow the charger manufacturer’s instructions. When charging multiple batteries, ensure the charger supports the number of cells being charged and that contacts are clean and properly aligned. Store unused batteries in their original packaging or in a cool, dry place away from direct sunlight.

What to consider before purchase

• Check device compatibility with AAA NiMH cells and whether pre‑charged NiMH is acceptable for your application
• Assess whether 800 mAh capacity meets the runtime expectations of your device
• Confirm you have a suitable NiMH-compatible charger if you plan to recharge the cells
• Consider buying spares if you need long continuous runtimes or frequent replacements

Usage recommendations

For consistent results, rotate batteries within multi‑cell devices and recharge before batteries are fully depleted when possible. Keep batteries and chargers dry and at moderate temperatures; avoid extreme heat. Dispose of cells according to local regulations for rechargeable batteries when they reach end of life.
