Tubular Batteries are becoming more popular for Home UPS systems and have several advantages compared to flat plate batteries.  A more complex design increases the manufacture cost but the high electrical efficiency and extra long life make tubular batteries suitable for both domestic and industrial applications. Good tubular batteries can last unto 2, 3 or 4 times as long as lead acid batteries. The cost of tubular batteries can be up to double that of a lead acid battery, however if you have a high efficiency inverter then go for a tubular battery, you will not regret it.
