Connection & Operating Recommendations
Use the ER18505 only in equipment designed for a 3.6V Li-SOCl₂ primary lithium cell in the A-size format. Its voltage and chemistry differ from conventional alkaline and rechargeable batteries, even when the physical formats appear similar.
- Voltage Compatibility: Confirm that the equipment supports a 3.6V Li-SOCl₂ primary battery. Do not substitute it directly for a 1.5V alkaline or 1.2V NiMH cell.
- Current Requirements: Match the battery to the equipment’s operating and pulse-current requirements. Consider the stated maximum output-current rating when selecting the load.
- Capacity & Runtime: Actual operating time depends on load current, duty cycle, temperature and equipment operating conditions.
- Cell Size: Use the A-size format in a compatible battery holder or compartment.
- Polarity: Align the positive and negative terminals with the markings in the equipment.
- Primary Battery Use: Do not recharge the cell or connect it to a charging circuit.
- Storage & Handling: Keep the battery dry and protect its terminals from short circuits and contact with conductive objects.
- Replacement & Disposal: Follow the equipment manufacturer’s battery replacement procedure and dispose of used cells through an appropriate battery collection facility.
