Lithium Battery Akyga AKY1997 ER26500 C A Li-SOCl2 3.6V / 8500mAh

Akyga® AKY1997 is an industrial ER26500 (Li-SOCl₂) lithium battery designed for long-term power supply to devices operating in demanding environmental conditions. It has a voltage of 3.6 V, a high capacity of 8500 mAh and a wide operating temperature range up to +85°C, making it an ideal power source for professional applications.

What makes the ER26500 AKY1997 battery stand out?

Exceptionally high energy density

The Li-SOCl₂ (lithium-chloride) cell offers one of the highest capacities available among batteries of this size. With 8500 mAh, it can power devices for many years without the need for replacement.

Resistance to high temperatures – up to 85°C

The ER26500 battery from Akyga Battery maintains voltage and capacity stability even in elevated ambient temperatures, which makes it suitable for devices operating in harsh environments – including outdoor installations, control cabinets and field equipment.

Long service life and low self-discharge

Ideal for devices with low power consumption in standby mode – such as gas detectors, energy meters, GPS trackers and data loggers – where reliable operation for 10 to 20 years may be required.

Disposable (non-rechargeable) battery

The AKY1997 is a single-use battery and must not be recharged. Attempting to recharge it may result in damage or hazardous situations.

Typical applications for the ER26500 battery

Thanks to its exceptional durability, voltage stability and resistance to extreme conditions, the AKY1997 lithium battery is ideal for a wide range of professional applications where reliability over many years without servicing is important:

• GPS modules and location trackers – indispensable for long-term monitoring of vehicles, containers, shipments or field resources, where lack of access to mains power requires batteries with very low self-discharge.
• Data loggers – devices that record temperature, humidity, vibration, voltage or pressure in transport, cold stores, laboratories and warehouses – the ER26500 battery provides them with power for many months or years of continuous operation.
• Alarm systems and wireless sensors – including smoke, gas, motion and flood detectors, which must remain active even when there is no mains power supply. The AKY1997 guarantees continuous operation in standby mode and immediate readiness to respond.
• Utility meters – water, gas and electricity – especially in smart metering solutions, where data is transmitted cyclically. The ER26500 battery powers data transmission modules and internal memory without the need for frequent replacement.
• Emergency power systems and telemetry devices – used in industrial automation, SCADA systems, precision agriculture, energy and environmental infrastructure. The battery ensures continuity of data transmission even in remote and hard-to-reach locations.
• Logistics security – RFID tags, smart packaging, shipment tracking systems – AKY1997 supports Logistics 4.0 solutions, where long and trouble-free operation of identification or location devices without access to external power is essential.
