Description

The Energizer CR2025 is a 3V lithium coin cell battery measuring 20mm diameter by 2.5mm thickness, supplied in a 2-pack blister. The CR2025 designation indicates the chemistry (CR = lithium manganese dioxide), diameter (20mm) and thickness (2.5mm), distinguishing it from thicker CR2032 or thinner CR2016 cells that share the same 20mm footprint.

Designed for low-drain electronics that draw power intermittently rather than continuously, the CR2025 powers car key fobs, digital watches, glucose monitors, fitness trackers, bathroom scales, remote controls, LED tea lights, and small calculators. The lithium chemistry provides a flat 3V discharge curve across most of the battery's usable life, avoiding the gradual voltage drop seen in alkaline chemistries, which means devices continue working at full function until the cell is nearly depleted.

Each CR2025 carries a shelf life of up to 10 years when stored at room temperature, making it suitable for emergency devices, backup applications, and stock rotation in commercial settings. The cell operates across a temperature range of -30°C to +60°C, maintaining voltage stability in car interiors during winter and in outdoor sensors during summer. Energizer rates these cells with leakage resistance to protect the device compartment if a cell is left installed past its usable life.

Alternative labels for the CR2025 include DL2025, ECR2025, BR2025, and KCR2025 depending on the manufacturer, but the physical and electrical specifications remain identical across these designations. The CR2025 is not rechargeable and must be disposed of according to local battery recycling regulations.

Frequently Asked

What's the difference between CR2025, CR2032 and CR2016?

All three share the same 20mm diameter and 3V voltage, but differ in thickness. The CR2016 is 1.6mm thick, the CR2025 is 2.5mm, and the CR2032 is 3.2mm. Thicker cells have higher capacity and longer runtime but will not fit in devices designed for thinner cells. Always match the exact cell size printed on the device or the old battery.

How long does a CR2025 last in a key fob?

Typical car key fobs using CR2025 cells last 2-4 years depending on how frequently the fob is used. High-use fobs with start/stop ignition functions may drain faster. If the key fob range shortens or buttons become unresponsive, replace the cell.

Can I use a CR2032 instead of a CR2025?

No. The CR2032 is 0.7mm thicker and will not fit in a battery compartment designed for a CR2025. Forcing a thicker cell into a tight compartment can damage the device or prevent the cover from closing properly.

Are these batteries rechargeable?

No. CR2025 lithium cells are single-use and must be replaced when depleted. Attempting to recharge a non-rechargeable lithium cell can cause leakage, swelling or rupture. Dispose of used cells at a battery recycling point.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund. Customers pay return shipping. Made-to-order, special-order and clearance items cannot be returned. See full returns policy.
