DUSLAN ER18505 3.6V 3600mAh lithium primary battery 3-pack
Three 3.6 V lithium-thionyl-chloride cells deliver 3600 mAh each for long-life backup, metering and industrial use
- 6 V nominal voltage powers industrial sensors reliably
- 3600 mAh capacity supports long-term meter operation
- 55 °C to +85 °C range suits harsh environments
- Li-SOCl2 chemistry delivers stable output for backup circuits
- 5 mm × 50.5 mm size fits standard ER18505 holders
Primary lithium cells for long-life devices
These ER18505 batteries use lithium thionyl chloride chemistry to deliver a nominal 3.6 volts and 3600 mAh capacity. They suit equipment that must run for years without maintenance such as utility meters, medical instruments, or remote telemetry units. The three-pack provides spares for multi-cell installations or future replacements.
3600 mAh capacity with wide temperature range
At a 1 mA load the cells hold 3.6 volts from minus 55 to plus 85 degrees Celsius. Open-circuit voltage measures 3.66 volts at 20 degrees Celsius. Self-discharge stays low when stored below 30 degrees Celsius, giving years of standby life. Capacity drops sharply under heavy continuous drain or if the voltage falls below the device cut-off point.
Supplied as three loose cells with solder tabs
Each unit measures 18.5 mm diameter by 50.5 mm height and weighs 28 grams. Tabs allow direct PCB attachment but soldering must finish in seconds to avoid heat damage. The cells are primary only; recharging is unsafe. Do not mix with other models in series and discard any cell with a damaged casing.

Questions about this item
Will the 18.5 mm diameter ER18505 cells fit the same holder as my old 3.6 V lithium batteries?
Each cell measures 18.5 mm in diameter and 50.5 mm in height, so they match the standard ER18505 form factor used in many legacy boards.
How can I confirm the 3.6 V nominal output is healthy after installation?
Measure open-circuit voltage with a multimeter; a fresh cell reads about 3.66 V at 20 °C, while 3.6 V under a 1 mA load confirms normal operation.
Does the three-pack include tabs or soldering hardware, or must I buy them separately?
The pack contains only the three bare lithium thionyl chloride cells; any tabs, holders or soldering equipment must be sourced separately.
