Battery Duracell BLM-1 (DR9630) — lithium photo/backup cell

Duracell BLM-1 (DR9630) is a lithium coin cell designed for photographic equipment and electronic memory backup. It supplies a stable 3V output and is intended for devices that require a compact lithium power source to retain settings, date/time, and low-drain backup functions over long storage periods. The chemistry and form factor make it suitable for applications where long shelf life and dependable performance in low-discharge conditions are needed.

Advantages

This lithium photo/backup cell offers consistent voltage during long-term storage and reliable operation in low-drain circuits. Its compact coin shape fits in many cameras, motherboards, and small electronic devices that specify the BLM-1/DR9630 form factor. The battery’s chemistry supports long shelf life and predictable behavior across a wide temperature range, reducing the need for frequent replacements in backup applications.

Suitable for

• Digital cameras and photographic equipment requiring a coin-type lithium backup cell
• Memory and real-time clock backup on motherboards and embedded systems
• Calculators, small medical devices, and handheld electronic instruments with low current consumption
• Any device specifying a BLM-1/DR9630-compatible coin cell for settings retention

Key specifications

• Cell type: lithium coin cell
• Nominal voltage: 3 V
• Typical capacity: suited for low-drain, backup applications (coin cell range)
• Form factor: compact coin/photographic backup size compatible with BLM-1/DR9630 devices
• Storage characteristics: long shelf life and low self-discharge typical of lithium chemistry
• Operating temperature: suitable for typical consumer electronic temperature ranges

How to use

Install the battery in the device following the manufacturer’s orientation mark, ensuring correct polarity. For devices with a battery holder or compartment, press the cell gently into place until it is secure. Replace the cell when device indicators show loss of memory, incorrect time/date, or reduced function. Store unused batteries in a cool, dry place away from metal objects and extreme heat to maintain shelf life.

Usage recommendations

Use this lithium cell only in devices that specify compatibility with the BLM-1/DR9630 form factor and lithium chemistry. Dispose of spent cells according to local regulations for battery recycling. Avoid short-circuiting the terminals and keep batteries out of reach of children.
