DELTACO CR1220 Lithium Button Cell Batteries, 3 V, 40 mAh, 10-Pack

The DELTACO CR1220 lithium button cell batteries, 3 V, 40 mAh, 10-pack provide single-use power for compact electronics that require a specific coin cell form factor. These lithium batteries deliver 40 mAh of capacity at a steady 3 V output, a voltage rating standard for coin cells used in low-drain hardware rather than high-draw equipment. Each unit matches the physical dimensions required by compatible device compartments and functions as a direct replacement for hardware designed around this size. The lithium chemistry offers a stable discharge curve during operation.

These cells are suitable for watches, calculators, and car key fobs that accept the standard size, and they also serve as reliable power sources for electronic memory backup systems. The design allows straightforward installation in compatible small electronic devices without specialised tools. Broad compatibility extends to hardware requiring specific equivalent part numbers for proper operation, and correct matching of the cell specification helps prevent damage to sensitive low-power circuitry. Keeping spares on hand reduces downtime when a critical remote or sensor loses charge.

• Free of mercury, lead, and cadmium for safer household disposal.
• Interchangeable with DL1220, ECR1220, BR1220, and 280-208 for devices listing these equivalent numbers.
• Also replaces DL1220B, BR1220-1W, CR1220-1W, and KCR1220 to broaden compatibility across various small electronics.
• Fits standard replacements for LM1220, 5012LC, SB-T13, and L04 to cover common coin cell designations.
• Total pack weight of 10 grams allows for lightweight storage in travel kits.
