I had to replace the battery in 14 months. The battery came with just 12 months warranty in our new Jeep Compass Petrol AT. Had to shell out Rs.9500/-.
I have used Toyota, Honda, Hyundai, Suzuki cars and never had to change battery in 4 years.
Please invest your money wisely. After spending Rs.23 lakhs you are still given a vechical of 1 year battery warranty when 5 year warranty battery is common.
