Replacement Key Fob Battery

This Cameron Sino cell replaces the original battery in Land Rover Discovery 3, LR3 and Range Rover Sport key fobs. It is a 50mAh lithium-ion unit rated at 3.0 volts with a certified ISO9001, RoHS and CE build. The pack weighs 4.0g and measures 23.60 x 23.60 x 9.50mm. A fully decoded chip ensures the remote functions exactly like the factory part.

Sustained Daily Use

The cell delivers 0.15Wh capacity to support repeated lock, unlock and alarm cycles over months of ownership. Built-in overcharge, over-discharge, over-voltage and short-circuit protection maintains stable voltage during temperature swings inside the fob housing. A new battery reaches peak performance after two or three full charge and discharge cycles. Do not store the unit above 60 °C or 140 °F to preserve long-term reliability.

Critical Fit Check

Compatibility depends on matching the original battery part number and the physical dimensions of 23.60 x 23.60 x 9.50mm before purchase. The connector must seat securely in the specific fob model listed for Discovery 3, LR3 SE, HSE and Sport Supercharged variants. Install using widely available online guides and avoid low-quality third-party chargers that can shorten service life.

Questions about this item

How much heat does the 50mAh key fob battery generate when the remote is used all day?

The lithium-ion cell produces negligible heat during normal remote operation and stays well within its 60°C storage limit.

What must I already own for this 3.0V replacement to work in my Land Rover Discovery 3?

You need the original key fob housing and a small screwdriver to open it and swap the 23.60×23.60×9.50mm cell.

Will the fully decoded chip in this 50mAh battery communicate with the older LR3 immobiliser without re-pairing?

Yes, the decoded chip behaves like the factory unit so the existing immobiliser recognises it immediately.
