I already take three 'times service of battery in three month becouse the battery backup is not enough and suddenly down automatic and battery is repaired of three times but there is same as before". Whenever i go to the shop so the shopkeeper says go to the service centre. Service centre is not respond properly so im not satisfy with this item. I never expect the amaron service is like this. So i want replace my battery.
