When to choose this battery

• Use if your device or manual specifies CR2354 (or DL2354/ECR2354).
• Good for moderate-drain electronics that benefit from more capacity than smaller cells like CR2032.
• Avoid if your device requires a different size (e.g., CR2032, CR2450); forcing a fit can damage contacts or cause malfunction.
• For long-term standby at elevated temperatures and very low drain, consider a BR2354 variant (different chemistry) if recommended by the device maker.

Common uses

• Keyless entry remotes and security fobs
• Health and fitness sensors, monitors, and wearables
• Smart home and IoT sensors (motion, temperature, door/window)
• Watches, timers, and small electronics
• Memory backup for electronics and controllers

Expected runtime (estimates)

Actual life depends on device load, temperature, and duty cycle. As simple guidance:

Device type	Typical average draw	Expected life
Key fob (intermittent use)	5–20 μA average with brief pulses	1–3 years
BLE/IoT sensor	20–100 μA	3–12 months
Simple watch/timer	1–5 μA	2–5 years

Quick estimate: runtime (hours) ≈ capacity (mAh) × 0.7 ÷ average current (mA). The 0.7 factor accounts for real-world conditions.

Compatibility and alternatives

• Exact fit: CR2354 is 23 mm × 5.4 mm. Do not substitute different sizes.
• Not equivalent: CR2032 (20 × 3.2 mm) and CR2450 (24 × 5.0 mm) will not fit properly.
• Cross-reference: Other brands may mark this size as DL2354 or ECR2354.
• Chemistry variant: BR2354 (carbon monofluoride) favors very low-drain, long-term standby and higher heat tolerance at the expense of peak current capability.

Installation tips

1. Power off the device if possible. Note the battery orientation; the “+” side typically faces up.
2. Handle by the edges; avoid touching flat surfaces. If contacts are dull, gently wipe with a dry, lint-free cloth.
3. Insert without bending springs or clips. Confirm the cell sits flat and secure.
4. Test the device. Some remotes may need re-pairing or a reset after replacement.

Storage and safety

• Store in a cool, dry place in original packaging; avoid heat and direct sun.
• Keep out of reach of children. Coin cells are a choking and ingestion hazard. If swallowed, seek immediate medical attention.
• Do not recharge, short-circuit, crush, or incinerate.
• Tape battery terminals before disposal and recycle at an approved collection point.

FAQ

What batteries are equivalent to CR2354?

CR2354 is the IEC size. Equivalent labels from other brands may include DL2354 and ECR2354. Always match the 23 mm × 5.4 mm size and 3 V lithium chemistry.

Can I use a CR2032 or CR2450 instead?

No. They are different sizes and capacities. Using the wrong size can cause poor contact, damage, or device failure.

How long will a CR2354 last in a key fob?

Typically 1–3 years depending on usage, temperature, and how often the fob transmits. Frequent use and cold weather reduce life.

Is the CR2354 rechargeable?

No. It is a primary (non-rechargeable) lithium battery. Never attempt to charge it.

When should I choose BR2354 instead of CR2354?

Choose BR2354 if the device specifies it or requires long-term, very low-drain standby at elevated temperatures. For higher pulse currents, CR2354 is usually preferred.
