What is an inverter battery?

An inverter battery is a type of rechargeable battery specifically designed to power an inverter during power outages. It stores DC (direct current) electricity and converts it into AC (alternating current) electricity via the inverter to run household appliances.

What are the different types of inverter batteries?

The most common types are Lead-Acid batteries, which include Flat Plate and Tubular batteries. Lithium-ion batteries are also becoming increasingly popular due to their longer lifespan and faster charging capabilities.

How long does an inverter battery typically last?

The lifespan of an inverter battery depends on its type, usage, maintenance, and the depth of discharge. Tubular lead-acid batteries can last 5-10 years, while lithium-ion batteries can last 10-20 years or more.

What is the difference between a flat plate and a tubular inverter battery?

Tubular batteries generally offer a longer lifespan and better performance, especially under deep discharge cycles, making them more suitable for inverters. Flat plate batteries are typically less expensive but may have a shorter life and require more frequent maintenance.

How should I maintain my inverter battery?

Regularly check the water level (for lead-acid batteries) and top it up with distilled water. Keep the terminals clean and free from corrosion. Ensure proper ventilation to prevent overheating, and try to avoid deep discharges to prolong battery life.
