It also begs the question of whether the charging system is set for flooded or AGM batteries?
If you can trust Jeep UK you have the answer to the technology the car was built for.
As I said before I would be getting the recommendations from the world's better battery makers, they unsurprisingly are pretty on the ball regarding batteries.
Note, not Halfords or any vendor or brand holder, but the makers themselves. Then a pattern should emerge that hopefully endorses Jeep UK's story.
Just that buying a quality battery, even at the good discounts available in that industry, will still be quite costly compared to many budget offerings.
