Runtime and high-current loads
Nominal energy is approximately 2,400Wh. Actual usable energy is lower and depends on discharge rate, depth of discharge, battery condition, temperature, cable losses and charging availability.
The 1,800A rating applies for five seconds only; it is not a continuous-current rating. Before using a power inverter, confirm the battery’s permitted continuous discharge current and ensure the cable, fuse, isolator and connections are correctly rated.
Installation requirements
This is a heavy battery. Confirm the installation structure can safely support approximately 42.5kg, measure the available space and secure the battery against movement. Follow the manufacturer’s orientation and ventilation requirements and use appropriate lifting practices.
Recharge promptly after use and periodically during storage. Avoid repeated excessive discharge, which can shorten AGM battery life.

Frequently asked questions
Can this battery be charged from solar?
Yes, when used with an AGM-compatible solar controller whose charge settings and current output suit the battery.
Can it support a high-power inverter?
Capacity alone cannot confirm this. Check the battery’s continuous-discharge limit, inverter DC current, appliance surge, cable size, voltage drop and fuse rating.
