❓ Frequently Asked Questions
Q
What type of battery is the ER9V, and what makes it suitable for long-term applications?
The ER9V is a Lithium Thionyl Chloride (Li-SOCl₂) battery. This chemistry is renowned for its extremely high energy density, very low self-discharge rate (≤1% per year), and wide operating temperature range, making it ideal for long-term and remote applications such as utility metering, alarms, and IoT devices.
Q
What is the operating temperature range of the ER9V battery?
The ER9V operates reliably across an ambient temperature range of -55°C to +85°C. This extreme range makes it well-suited for both harsh outdoor environments and high-temperature industrial settings.
Q
How long can the ER9V battery be stored before use?
The ER9V has a storage life of 10 years or more, with a yearly self-discharge rate of no more than 1%. This makes it an excellent choice for backup power and devices that are deployed and left unattended for extended periods.
Q
What is the maximum pulse current the ER9V can deliver?
The ER9V can deliver a maximum pulse current of 50mA. These pulses are specified at 100ms duration, drained every 2 minutes, making it capable of powering devices that require short bursts of higher current, such as wireless transmitters or sensors.
Q
What is the nominal capacity of the ER9V, and how is it measured?
The ER9V has a nominal capacity of 1200mAh. This capacity is measured by discharging the battery down to a cut-off voltage of 6.0V at a standard discharge current of 0.5mA, which reflects typical low-power application usage.
Q
What are the physical dimensions and weight of the ER9V battery?
The ER9V measures 26.5mm (Width) × 17mm (Thickness) × 48.8mm (Length) and weighs approximately 40 grams. Its compact form factor makes it a direct replacement for standard 9V battery applications that require higher voltage and extended service life.
