INVERTER BATTERY IS ALSO KNOWN AS UPS BATTERY. IT IS A LEAD ACID RECHARGEABLE BATTERY USED WITH HOME INVERTER & UPS. THE MAIN COMPONENT OF AN INVERTER BATTERY IS THE LEAD INSIDE IT. HIGHER LEAD ENSURES BETTER PERFORMANCE AND QUALITY. LEAD ACID INVERTER BATTERIES USUALLY REQUIRE WATER TOP-UP ONCE IN 3-6 MONTHS. THE POWER FACTOR IS USUALLY MEASURED IN AMPERE HOUR(AH). THE FOLLOWING FACTORS ARE TO BE CONSIDERED BEFORE BUYING ANY INVERTER BATTERY.

1. HOW MUCH BACKUP TIME DO YOU NEED? IT DEPENDS ON THE AH OF THE BATTERY. MORE AH MEANS MORE BACKUP TIME. EG. - A BATTERY OF 150 AH PROVIDES A BACKUP TIME OF 3 - 4 HRS. AT FULL LOAD.
2. DEPENDING ON THE INTERNAL STRUCTURE, YOU CAN CHOOSE BETWEEN A FLAT PLATE INVERTER BATTERY AND A TUBULAR INVERTER BATTERY. MOST PEOPLE DON'T KNOW THAT A TUBULAR INVERTER BATTERY HAS A BETTER LIFESPAN WHILE A FLAT PLATE INVERTER BATTERY PROVIDES BETTER BACKUP.
3. THE WARRANTY OF THE INVERTER BATTERY IS A CRUCIAL FACTOR. REMEMBER TO READ THE WARRANTY DETAILS CAREFULLY AS THERE ARE TWO TERMS RELATED TO IT - REPLACEMENT GUARANTEE AND PRO-RATA WARRANTY. BATTERY WITH 36 MONTHS(18+18 MONTHS) MEANS THAT THE FIRST 18 MONTHS ARE FOR FREE REPLACEMENT AND THE REST 18 MONTHS ARE FOR PROVIDING A NEW BATTERY AT A DISCOUNTED PRICE.
