The best batteries for inverters are deep cycle batteries like Eastman's Inverter Batteries, designed for prolonged power backup with minimal maintenance.

Two main types of inverter batteries are tubular and flat plate, each offering distinct advantages. Choose based on your specific power needs and preferences.

The choice between a 150Ah and a 200Ah inverter battery depends on your power requirements. Opt for 200Ah for longer backup and higher power needs.

When buying an inverter battery, consider factors like battery type, capacity, warranty, and maintenance requirements. Ensure compatibility with your inverter for optimal performance.

Maintain inverter battery health by regular charging, avoiding deep discharges, checking water level & replinishing it and ensuring proper ventilation. Follow manufacturer guidelines for extended lifespan.

LIt's not advisable to connect batteries of different capacities, it can potentially damage the batteries. Use batteries with the same capacity and specifications for optimal performance and longevity.

Adding 2 batteries to an inverter is possible, but they should have the same capacity and type. Moreover, your inverter should be able to support two batteries and for this you need an inverter with atleas 24V rating. Follow manufacturer recommendations for a safe and efficient setup.

Running a fridge or any electrical device is primarily done by the invereter. A battery is source of power to the inverter. The battery capacity defines the duration of the backup based on the load begin run by the inverter. Ensure the inverter capacity meets both appliances' requirements for optimal performance.

Select the 200Ah inverter battery for extended backup and increased power needs. It ensures longer runtime and superior performance compared to the 150Ah option, catering to demanding applications effectively.
