How to use

Install the single D-size cell according to device polarity markings and enclosure instructions. This battery is intended for primary use and must not be recharged. For devices with intermittent high-current pulses, verify that the pulse current and duty cycle are within the battery's recommended limits. Store unused batteries in a cool, dry place and fit into the equipment only when ready for use. Observe device manufacturer guidance for replacing primary cells and follow local disposal regulations for lithium primary batteries.

Usage recommendations

For best long-term performance, use this LiSOCl2 D-size cell in low-drain or intermittent applications such as meters, sensors, alarms and remote monitoring equipment. Avoid charging attempts, short circuits and exposure to temperatures beyond the device and battery specifications. When designing systems, account for gradual capacity decrease over long deployment times and include appropriate low-battery indication or maintenance intervals.
