LONG DESCRIPTION – BOTTOM OF CATEGORY

Rechargeable batteries for electronic devices

Rechargeable batteries can be charged and reused multiple times.

They are suitable for many compatible household and electronic devices, including remote controls, toys, flashlights, computer accessories and portable equipment.

The current category contains nine products covering AA, AAA, 18650, 26650 and sealed 6 V battery formats.

AA rechargeable batteries

AA, also known as R6, is one of the most common battery sizes.

Compatible devices can include:

• remote controls;
• toys;
• flashlights;
• computer accessories;
• audio equipment;
• measuring devices.

AAA rechargeable batteries

AAA or R3 cells are smaller than AA batteries and are commonly used in compact electronics.

The range includes several AAA rechargeable options.

USB-C rechargeable AA batteries

The category includes four-piece sets of 1.5 V Li-ion AA batteries with direct USB-C charging.

One current set provides a stated capacity of 1466 mAh per cell.

USB-C rechargeable AAA batteries

Four-piece Li-ion AAA sets with direct USB-C charging are also available.

The current version provides a stated capacity of 440 mAh per cell.

USB-C charging

A built-in charging port reduces the need for a traditional multi-slot charger.

Always use a compatible power source and follow the battery instructions.

Ni-MH rechargeable batteries

Ni-MH technology is widely used in traditional AA and AAA rechargeable cells.

These batteries require a compatible Ni-MH charger.

Li-ion rechargeable batteries

Lithium-ion technology is used in both specially designed AA/AAA batteries and cylindrical cells such as 18650 and 26650.

Li-ion batteries require compatible charging equipment.

18650 batteries

The current range includes a lithium-ion 18650 cell with stated parameters of 3800 mAh and 4.2 V.

Always check exact device compatibility before use.

26650 batteries

The category also includes a 26650 Li-ion cell with a stated capacity of 5000 mAh and nominal voltage of 3.7 V.

18650 versus 26650

26650 cells are physically larger than 18650 batteries.

The two formats should not be treated as interchangeable unless the device specifically supports both.

Sealed 6 V batteries

A maintenance-free 6 V sealed battery is also available.

This type of product is different from AA, AAA and cylindrical lithium-ion cells and is intended for compatible specialised equipment.

Rechargeable versus disposable batteries

Rechargeable cells can replace disposable batteries only when they are electrically and physically compatible with the device.

Battery voltage

The current category includes products with several different voltages, including:

• 1.2 V;
• 1.5 V;
• 3.7 V;
• 4.2 V;
• 6 V.

They are not automatically interchangeable.

What does mAh mean?

Battery capacity is commonly expressed in milliamp-hours.

It provides information about stored charge but does not directly determine exact device runtime.

Is a higher mAh rating always better?

No.

Capacity must be considered together with voltage, chemistry and physical format.

Rechargeable batteries for remote controls

AA and AAA rechargeable batteries can be useful for frequently used remote controls when compatible with the device.

Rechargeable batteries for toys

Reusable cells can reduce the need for frequent disposable-battery replacement in compatible electronic toys.

Rechargeable batteries for flashlights

Flashlights may use AA, AAA, 18650, 26650 or integrated batteries.

Always follow the flashlight manufacturer's specification.

Rechargeable batteries for keyboards and mice

Wireless computer accessories frequently use AA or AAA cells.

Keeping one charged spare set can be convenient.

Four-battery packs

Several AA and AAA products are sold in sets of four.

Check how many batteries the intended device requires.

Choosing a charger

A charger must match:

• battery chemistry;
• voltage;
• format;
• supported size;
• charging requirements.

Do not assume that one charger can safely handle every rechargeable battery.

Batteries with integrated charging ports

USB-C AA and AAA batteries have their own charging connection and differ from traditional cells charged in a slot charger.

Correct polarity

Always insert batteries according to the positive and negative markings in the device.

Mixing rechargeable batteries

Avoid combining batteries with different chemistry, voltage, capacity, age or charge level in one device.

Mixing disposable and rechargeable batteries

Do not mix disposable and rechargeable batteries unless the device manufacturer specifically permits it.

Safe charging

Use compatible charging equipment and stop charging if a battery becomes excessively hot, swollen or damaged.

Damaged batteries

Do not use cells that are swollen, cracked, deformed, corroded or otherwise damaged.

Battery storage

Store rechargeable batteries in a dry location away from excessive heat.

Keep loose cells away from metal objects that could short the terminals.

Transporting batteries

Protect the battery terminals during transport, particularly with lithium-ion cells.

Caring for Li-ion cells

Protect lithium-ion batteries from short circuits, overheating, puncture and impact.

Caring for Ni-MH batteries

Use a compatible Ni-MH charger and keep batteries from the same set together where practical.

When should a battery be replaced?

Consider replacement when runtime drops significantly, charging becomes unreliable, the battery overheats or physical damage appears.

Battery recycling

Used rechargeable batteries should be taken to an appropriate battery collection point rather than disposed of with normal household waste.

How to choose the right battery

Check:

• battery format;
• voltage;
• chemistry;
• capacity;
• dimensions;
• charging method;
• terminal design.

What should you check before buying?

The most important factors are battery format, voltage, capacity, chemistry, pack size, charging method and compatibility with both the device and charger.
