which brand inverter battery has longest lifespan?
p.s- u can suggest specific model as well.
Inverter batteries lifespan mostly depends upon the charge discharge cycles irrespective of any specific brand
In urban areas due uninterrupted power supply batteries run for almost 10-12 years due to low or no power cuts
Whereas in rural areas where powercuts are more prominent, batteries go dead in 2-3 years
Luminous Tubular
from my usage, Amaron/Exide tall tubular batteries mostly come around 4.5-5yrs max and model/capacity depends on your requirements (like backup of how many fans/devices you are going to use for how many minutes) as you have from 100 to 220ah batteries (highest price)
Amaron inverter batteries are good. I have been using Amaron batteries for the last 5 years and so far it is working well.
Eastman , last battery lasted for 8 years and still running .. 50% backup .
Exide started failing 3.5 years onward .
Consider LiFePo prismatic cell based batteries. Understand about discharge levels & cycles in regular lead acid batteries and these batteries to appreciate the price.
Livguard 84 months warranty .
60 + 24
Okaya tubular
