Duracell CR2450 3V Lithium Coin Battery – DL2450 / ECR2450
A reliable 3V lithium coin battery for devices that require the exact CR2450 designation – a practical replacement for remotes, meters, watches, security devices and other compact electronics.
The Duracell CR2450 is a non-rechargeable lithium battery in a coin-cell format with a 3V nominal voltage. Its designation also corresponds with DL2450 and ECR2450 where the device uses the same battery type.
Its 24.5 mm × 5.0 mm dimensions are essential for a correct fit in the battery holder. It is designed for devices that need dependable power in a very compact space.
Before ordering: check the marking on the existing battery and the holder dimensions. CR2450 is not interchangeable with a CR2032 or other 3V coin cells of different dimensions.
The right replacement for a device that needs CR2450
- Exact CR2450 format provides the correct fit for devices designed for a 24.5 mm diameter, 5.0 mm high coin battery.
- Stable 3V nominal voltage suits many small electronic devices specified for this power source.
- Lithium technology is well suited to compact devices where long standby availability is important.
- Up to 10 years in storage, as stated by the manufacturer, helps keep a useful replacement ready when needed.
- One battery in a blister pack is a practical option when a single quality replacement is required.
When a device becomes unreliable, check its battery first
A weak coin battery can cause reduced remote range, display failure, inaccurate operation or a device that will not switch on. Replacing it with the correct battery type is a simple first step when resolving these symptoms.
CR2450 is suitable only when it is explicitly specified by the device manufacturer. Matching voltage alone is not enough, as coin cells differ in diameter and thickness.
- Remote controls and key fobs that use a CR2450 battery.
- Meters, watches, electronic accessories and other compatible devices.
- Security and other compact devices specified for CR2450, DL2450 or ECR2450.
Before replacement, switch off the device where its instructions allow this and follow the + / − polarity markings in the battery compartment.
Designations that help you choose correctly
The most reliable reference is the marking on the existing battery or the device instructions. Compatible devices may use the CR2450, DL2450 or ECR2450 designation.
- CR2450 – the standard designation for this 3V lithium coin-cell format.
- DL2450 – a designation used for the matching Duracell format.
- ECR2450 – an alternative designation in the same size group for compatible devices.
Important: do not choose a battery by appearance or voltage alone. Compare the designation, diameter and height with the old battery before ordering.
Compact lithium power for specialist devices
The coin-cell format fits devices with very limited battery space. CR lithium batteries are designed for single use and provide the 3V power required by many specialist electronic devices.
As this is a non-rechargeable battery, replace it with a new battery of the correct type when depleted. Do not use a charger or attempt to recharge it.
Correct replacement in a few steps
- Open the battery compartment according to the device manufacturer’s instructions.
- Check that the old battery is marked CR2450, DL2450 or ECR2450, and note its orientation.
- Insert the new battery with the correct polarity and close the battery compartment securely.
Keep the battery in its original packaging until use and prevent its terminals from touching metal objects such as keys or coins.
Safe handling of coin batteries
- Keep batteries out of reach of children.
- Do not recharge, disassemble, crush or heat the battery.
- Take used batteries to a suitable battery collection point; do not dispose of them with mixed household waste.
Coin batteries are dangerous if swallowed. If ingestion is suspected, seek immediate medical attention.
