JCB RTU – AAA 900mAh NiMH Rechargeable Batteries, Pre-Charged, 4 Pack

JCB RTU AAA 900mAh – Pre-Charged NiMH Rechargeable Batteries, 4 Pack

Ready to use straight from the package, rechargeable and designed to retain their charge during storage. JCB Ready To Use AAA batteries combine the convenience of disposable batteries with the economy of rechargeable NiMH technology.

The JCB RTU AAA 900mAh batteries provide a practical power solution for everyday household and portable electronics, including flashlights, remote controls, toys, audio equipment and other compatible AAA-powered devices.

Thanks to Ready To Use (RTU) technology, the batteries are pre-charged during manufacturing and can be used immediately after purchase.

Their low self-discharge characteristics also allow them to retain much of their stored energy over extended periods.

Ready To Use – Pre-Charged and Ready When Needed

Unlike conventional older rechargeable batteries that may lose a significant amount of charge during storage, JCB Ready To Use cells are designed to minimise self-discharge.

The batteries leave the factory approximately 70% charged, meaning they can be used directly from the package without requiring an initial charging session.

This makes them particularly convenient for devices that need immediate power or are only used occasionally.

Low Self-Discharge – Up to 80% Capacity After One Year

One of the main advantages of these rechargeable batteries is their ability to retain stored energy.

After 12 months of storage, the batteries can retain up to 80% of their capacity.

This makes them a practical choice for spare batteries, household equipment and electronics that are not used every day.

The reduced self-discharge rate helps ensure the batteries remain useful even after extended storage.

NiMH Technology – Recharge Instead of Replace

The batteries use NiMH (Nickel-Metal Hydride) chemistry, allowing repeated charging and reuse.

Compared with disposable alkaline batteries, they offer several practical advantages:

• Rechargeable operation for repeated use.

• Lower long-term running costs in frequently used devices.

• Reduced disposable battery waste.

• Low self-discharge for improved charge retention during storage.

• Factory pre-charging for convenient first use.

Rechargeable batteries are particularly useful in equipment that requires frequent battery replacement.

900mAh Capacity and 1.2V Nominal Voltage

Each battery provides a minimum capacity of 900mAh and a nominal voltage of 1.2V.

This makes the cells suitable for a wide variety of compatible devices using standard AAA batteries.

Actual runtime depends on the device's power requirements, usage conditions and battery charge level.

Please note: NiMH rechargeable batteries have a nominal voltage of 1.2V, compared with 1.5V for standard alkaline cells. Always check that your device supports rechargeable NiMH batteries.

Standard AAA Size – Versatile Everyday Compatibility

The batteries use the familiar AAA / HR03 / R03 size.

Typical applications include:

• LED flashlights and headlamps compatible with AAA NiMH cells.

• Remote controls for televisions and household electronics.

• Wireless keyboards and computer mice.

• Children's toys.

• Portable audio equipment.

• Digital thermometers.

• Other compatible household electronics.

Their low self-discharge characteristics make them especially useful in devices that may remain unused for extended periods.

Economical and Reusable Power

Rechargeable batteries help reduce the need for repeatedly purchasing disposable cells.

With appropriate charging and care, a single set of JCB RTU batteries can be used many times, helping reduce long-term operating costs and battery waste.

Convenient Four-Battery Pack

The product is supplied in a blister pack containing four AAA rechargeable batteries.

This is a practical quantity for powering equipment that requires four AAA cells or keeping spare rechargeable batteries available.
