Exide industries limited is a company which engage in making rechargeable batteries and invertors. I always prefer exide batteries because they are very good and long lasting. Battery backup they provide is also up to the mark. I purchased a battery for my car 6 years back and its works fantastic between these 6 years. 2 or three days back it just discharged.
You know that the life of car batteries is 3-4 years but my exide battery works for 6 years. That is more than expected.
