Car Battery - What all things to look for, Which is the best performing Battery

[Joe]

Hi Dears,

My AC Delco battery is not holding charge anymore just after 14 months of purchasing new, the indicator on battery is still showing green color but i had to jump start the battery last 2 times.

Before spending hard earned money on battery again, please advise what all things to check before purchasing a new battery, and which are the best reliable batteries in your experiance.

Car : Toyota Prado 2015, VXR V6 Full option.

Thanks,
Joe
