As I understand , batteries last about 2yrs. Because batteries only are used mainly during startup engine. After start up, alternator will provide electrical power. If battery dies in 6 months,

1. Battery fault. Faulty goods.
2. Wrong battery voltage for your car model. Chk ya car manual or Internet
3. Alternator not charging battery.( not likely)
