❓ Frequently Asked Questions
Q What does the model number ER14505M 1S4P mean?
The model ER14505M 1S4P indicates a lithium thionyl chloride (Li-SOCl₂) battery pack configured with 1 cell in series and 4 cells in parallel. This configuration delivers a nominal voltage of 3.6V while significantly increasing the overall capacity to 8800mAh.
Q What is the nominal capacity and how is it measured?
The nominal capacity of this battery is 8800mAh, measured by discharging the battery down to a cut-off voltage of 2.0V at a very low current of 0.5mA. This represents the total usable energy the battery can deliver under standard conditions.
Q What is the maximum pulse current the ER14505M 1S4P can handle?
The battery supports a maximum pulse current of 1500mA. These pulses are rated at 100ms duration and must be spaced at least every 2 minutes to prevent excessive heat buildup and to maintain battery performance and longevity.
Q What temperature range is this battery suitable for?
The ER14505M 1S4P is designed to operate reliably across an extremely wide ambient temperature range of -55°C to +85°C. This makes it ideal for harsh industrial environments, outdoor deployments, and applications in extreme climates.
Q How long can the ER14505M 1S4P battery be stored, and what is its self-discharge rate?
This battery offers a storage life of 10 years or more, with an annual self-discharge rate of 1% or less. This makes it an excellent choice for long-term applications such as smart metering, asset tracking, and other IoT devices that require infrequent maintenance.
Q What are the typical applications for the ER14505M 1S4P battery?
Thanks to its high capacity, wide temperature tolerance, low self-discharge, and long shelf life, the ER14505M 1S4P is widely used in applications such as wireless sensor networks, smart utility meters (water, gas, electricity), GPS tracking devices, industrial data loggers, and remote monitoring systems.
