A battery is a vital part of an inverter. The performance and life of an inverter largely depends on its battery. There are several classifications of inverter batteries. Here are few of them:
- Lead Acid Batteries
- Maintenance Free batteries
- Tubular Batteries
Lead Acid Batteries
Lead acid batteries are the most common inverter batteries. These are rechargeable in nature and produce large amount of current. They are light in weight and most economical. They usually last for 3-4 years. But they require regular maintenance. The electrolyte level check and topping up has to be done regularly. They also release harmful gases during charging and discharging. So they must be installed at a well ventilated place in home.
Maintenance Free Batteries
Maintenance free batteries are the sealed lead acid batteries that do not require electrolyte level check and topping up. They are fit and forget type batteries are safer compared to normal lead acid batteries. But they are costly compared to normal lead acid batteries and have a shorter life.
Tubular batteries are the most popular and efficient inverter batteries. They have a complex design, great efficiency, longer operational life (8+ years) and low maintenance. Because of so many advantages they are costly.
You have to be careful about the local batteries that are available in the market. People usually go for branded inverter set and local batteries. But its not a good combo. Local batteries should not be used. They have many down sides like poor efficiency, low safety, poor operational life and high maintenance. Do not kill your inverters by using these local and less efficient batteries.
